The widespread of incidence of asthma over large 20 years in South East Asian population, specially in children and aging group has caused some concerns to the government and scientific community. It may be due to over intake in artificial ingredients, polluted environment as well as intake foods triggering the inflammatory allergens.
Folate, also known as folic acid, vitamin B9, is a water soluble vitamin, found abundantly in leafy vegetables, citrus fruits, beans, whole grain, etc. The vitamin plays an important role in synthesize DNA, repair DNA, and methylate DNA as well as to act as a cofactor in certain biological reactions, production of red blood cells for anemia prevention.
1. Serum levels of folate
Scientific studies, linking serum levels of folate associated to risk of asthma have produced inconsistent results. The study by Ain Shams University showed that serum folate levels are significantly lower among atopics, and correlate inversely with the degree of atopy among asthmatics(1). Other researchers suggested that low serum folate and impaired folate metabolism may be a potential risk factors for development of asthma and atopic disease, according to The Capital Region of Denmark, in a random sample of 6784 persons from a general population aged 30-60 years participated in a health examination in 1999-2001, low levels of serum of folate were associated with self-reported doctor-diagnosed asthma and attacks of shortness of breath, but not with lung function or atopy(2). The Johns Hopkins School of Medicine study also indicated that the effects of serum levels of folate were associated inversely associated with high total IgE levels, atopy, and wheeze(3).
2. The effects of folate in maternal intake
Folic acid supplementation has an established role in early pregnancy for preventing neural tube defects, but its causes of childhood asthma and asthmatic symptoms in epidemiological studies have been inconclusive results. According to the University of Western Australia, maternal folic acid exposure may be associated to childhood asthma and wheeze(4). Other in the study of pre-natal FACSs exposure population showed a small increased risk of early wheeze, but no adverse association of respiratory or allergic outcomes(5). In the study using the data from an Australian prospective birth cohort study (n = 557) from 1998 to 2005. At 3.5 years and 5.5 years, 490 and 423 mothers and children participation, researchers at the The University of Adelaide, indicated the correlation of the supplementation with folate in pregnancy and incidence of childhood allergic asthma through epigenetic mechanisms and also associated with poorer respiratory outcomes in young children(6).
Since the search of the effect of folate intake in reduced risk and treatment of asthma have produced limitation of result, we concluded that folate deficiency or low levels of folate may be associated to increased risk of early onset of the disease, but multi centers and large sample size studies are necessary to improve its validation. Overdoses of folate may cause stomach problems, sleep problems, skin reactions, seizures, etc., please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Asthma in Vitamin K points of view
The widespread of incidence of asthma over large 20 years in South East Asian population, specially in children and aging group has caused some concerns to the government and scientific community. It may be due to over intake in artificial ingredients, polluted environment as well as intake foods triggering the inflammatory allergens.
Vitamin K(K1, phylloquinone; K2, menaquinones), is a fat soluble vitamin, found abundantly in leafy green vegetables, broccoli, and Brussels sprouts, etc. It is best known for promotion of coagulation and bone health.
Epidemiological studies focusing vitamin K in reduced risk and treatment of asthma have been inconclusive(a)(b)(c).
Menaquinone (vitamin K2), a variant of vitamin K, in a double blind study of 191 patients with bronchial asthma, showed an effective rate of 90.9% in mild patients, 86.7% in moderate patients, and 72.7% in severe patients(1). Other researchers suggested that treatment of menaquinone for long periods in patients with bronchial asthma indicated a significant inhibition of the disease(2). The data base of PubMed showed limitation in quantity of the research, we, therefore make no conclusion of the effectiveness of the vitamin in reduced risk and treatment of asthma. Overdoses can induce symptoms of Skin rash, Diarrhea, Nausea, Vomiting, Anemia, etc. Please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Asthma in Vitamin E points of view
The widespread of incidence of asthma over large 20 years in South East Asian population, specially in children and aging group has caused some concerns to the government and scientific community. It may be due to over intake in artificial ingredients, polluted environment as well as intake foods triggering the inflammatory allergens.
Vitamin E, a fat soluble vitamin, consisting eight different variants (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) with varying levels of biological activity(2), found abundantly in corn oil, soybean oil, margarine, wheat germ oil, sunflower,safflower oils, etc. plays an important role in neurological functions and inhibition of platelet aggregation, regulation of enzymatic activity, free radical scavenger, etc..
General consensus suggestion of increased dietary vitamin E intake is associated with a reduced incidence of asthma, due its antioxidant status, but epidemiological studeies, linking vitamin E inreduced risk and treatment of asthma have not been conclusive(a)(b)(c)(d)(e).
1. Serum levels of vitamin E
Serum levels of vitamin in asthmatic patients may be correlated to the occurrence of the diseases. The University of Tampere study of in five European rural settings with Children of 1133 mothers recruited during pregnancy, showed no associated of with allergies or asthma by 6 years of age regardless the concentration of vitamin E(1). and the study of the Yamaguchi University, also indicated no correlation of levels of vitamin E and asthma in the a total of Of 2796 students attending schools in Shunan, Japan, in 2006.(1a). The University of Medical Sciences study indicated other wise as treatment of fluticasone and vitamin E (50mg/day) showed an significantly increased of Serum level of Vitamin E, with improved FEV1 and FEV1/FVC ratio(2). The study of acute asthmatic attack in children, showed a high degree of reactive oxygen species formation causing considerable oxidative stress with the high level of oxidants Serum malondialdehyde (MDA) and low level of antioxidants(vitamin C, vitamin E and uric acid)(3). Researchers at the Oslo University Hospital, in the study of children of 7-12 yr with asthma (n = 50) and no asthma (controls) (n = 52)indicated that schoolchildren with asthma and rhinitis had reduced levels of the major serum antioxidant albumin, and poorly controlled asthma was associated with decreased vitamin E and transferrin levels(4).
2. The effects
The Northwestern University study indicated the opposing regulatory effects as allergic inflammation is inhibited by supplementation with the purified natural vitamin E isoform α-tocopherol but elevated by the isoform γ-tocopherol when administered at physiological tissue concentrations(5)(6). But according to University of North Carolina School of Medicine, γ-tocopherol (GT) significantly decreased (p < 0.05) internalization of attached zymosan bioparticles and macrophage expression of CD206, CD36 and CD86 in allergic asthmatics through downregulation of both innate and adaptive immune response elements, and atopic status(7). The composition containing 623 mg of gamma-tocopherol, 61.1 mg of d-alpha-tocopherol, 11.1 mg of d-beta-tocopherol (11.1 mg), and 231 mg of d-sigma-tocopherol capsule in Phase I human dosing study showed the decreased systemic oxidative stress, increased serum levels of gamma-tocopherol, and inhibited monocyte responses to LPS without any adverse health effects(8). In Ovalbumin (OVA)-sensitized Brown Norway rats, treatment of gamma-tocopherol (gammaT), inhibited the pathogenesis of both AR and asthma inflammatory pathways(9). Suggestion of oxidant stress and diminished antioxidant defenses may be a cause of asthmatic disease(10) and uncontrolled asthma and severe asthma pattern have impaired antioxidant defences and are thus most susceptible to the damaging effects of oxidative stress(11). 1500 IU of natural-source d-α-tocopheryl acetate daily for at least 16 weeks in volunteered asthmatic patient, showed to inhibited oxidant stress, through modulation of allergic inflammation and airway hyperresponsiveness in human atopic asthmatics in vivo(12).
Taking altogether, Aγ-tocopherol, a variant of vitamin E, may be effective in reduced risk and treatment of asthmatic disorder, but further large sample and in multi centers studies are necessary to validate it claims. Over doses of vitamin E supplement can cause symptoms of blurred vision, weakness, dizziness, nausea, diarrhea, etc., please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Asthma in Vitamin D points of view
The widespread of incidence of asthma over large 20 years in South East Asian population, specially in children and aging group has caused some concerns to the government and scientific community. It may be due to over intake in artificial ingredients, polluted environment as well as intake foods triggering the inflammatory allergens.
Vitamin D is a fat-soluble secosteroids found in small amount in few foods, including salmon, mackerel, sardines and tuna. The vitamin plays an important role in modulation of cellular proliferation, apoptosis induction, tumor growth suppression and promotion in absorption of minerals, including calcium, iron, magnesium, phosphate and zinc.
1. Serum of vitamin D
Epidemiological studies, linking the levels of serum 25-OH vitamin D with asthma may be inconclusive. The study of included 4,999 adults aged 30-60 years in 1999-2001. 3,032 of those included at baseline also participated at a follow-up examination 5 years later and 3,727 answered a 10 year follow-up questionnaire, showed no association of serum serum 25-OH vitamin D and the risk of asthma in Danish adults(1)(1a). Some researchers in the study of general Korean population suggested that vitamin D-insufficiency may have an increased likelihood of atopic dermatitis, but not asthma, allergic rhinitis, or IgE sensitization(2)(2a). But the study by Royal Brompton Hospital, London indicated otherwise in the study of relationships between serum vitamin D, lung function, and pathology in children with severe, therapy-resistant asthma (STRA)(3)(4) and 25 hydroxy vitamin D insufficiency is associated with bronchial asthma(4a) On the other hand, the study of iMayo Clinic indicated the correlation between serum 25(OH)D concentrations and positive pneumococcal antibody levels in all subjects regardless of asthma(5).
2. The benefits
According to the study by Universitätsmedizin Berlin, oral administration of vitamin D in vitamin D deficiency induced asthma, showed an increased expression of CD38 on B cells and a decreased T-cell-dependent proinflammatory cytokine production in doses of(6). In support to above study, Vitamin D found to decreaed inflammatory cytokine production from T-cell subsets implicated in asthma, according to Florida Atlantic University(7). In patient with in patients with steroid-resistant (SR) and steroid-sensitive (SS) asthma, oral administration of vitamin D, although exerted its anti-inflammatory and corticosteroid-enhancing effects in monocytes of patients with SR asthma and patients with SS asthma, the responses to corticosteroids in patients with SR asthma remained significantly lower than those in patients with SS asthma(8). Other in the study of the effect of vitamin D in severe therapy-resistant asthma (STRA) patients, showed an positive effect of 1α,25-dihydroxyvitamin D3, the active form of vitamin D in culture enhanced dexamethasone-induced IL-10 (Defective IL-10 expression causes a significantly diminished levels of anti-inflammatory interleukin (IL)-10))without marked effects on IL-13 or IL-17A production(9). Patients with severe asthma exhibited increased levels of TH17 cytokines.The study of King's College London, also suggested that 1,25(OH)2D3 inhibits TH17 cytokine production in all patients with moderate-to-severe asthma(10), enhances the frequency of Treg cells(11)and upregulates CD200 on peripheral human CD4+ T cells(12).
Taking altogether, without going into reviews, vitamin D used conjunction with other anti asthma medicine and its the active form 1α,25-dihydroxyvitamin D3, may be associated to reduced risk and treatment of asthmatic diseases. Over doses of vitamin D supplement may cause excessive calcium absorption, calcification, Urinary stones etc. please make sure to follow the guideline of the Institute of Medicine of the National Academies.

Vitamin D is a fat-soluble secosteroids found in small amount in few foods, including salmon, mackerel, sardines and tuna. The vitamin plays an important role in modulation of cellular proliferation, apoptosis induction, tumor growth suppression and promotion in absorption of minerals, including calcium, iron, magnesium, phosphate and zinc.
1. Serum of vitamin D
Epidemiological studies, linking the levels of serum 25-OH vitamin D with asthma may be inconclusive. The study of included 4,999 adults aged 30-60 years in 1999-2001. 3,032 of those included at baseline also participated at a follow-up examination 5 years later and 3,727 answered a 10 year follow-up questionnaire, showed no association of serum serum 25-OH vitamin D and the risk of asthma in Danish adults(1)(1a). Some researchers in the study of general Korean population suggested that vitamin D-insufficiency may have an increased likelihood of atopic dermatitis, but not asthma, allergic rhinitis, or IgE sensitization(2)(2a). But the study by Royal Brompton Hospital, London indicated otherwise in the study of relationships between serum vitamin D, lung function, and pathology in children with severe, therapy-resistant asthma (STRA)(3)(4) and 25 hydroxy vitamin D insufficiency is associated with bronchial asthma(4a) On the other hand, the study of iMayo Clinic indicated the correlation between serum 25(OH)D concentrations and positive pneumococcal antibody levels in all subjects regardless of asthma(5).
2. The benefits
According to the study by Universitätsmedizin Berlin, oral administration of vitamin D in vitamin D deficiency induced asthma, showed an increased expression of CD38 on B cells and a decreased T-cell-dependent proinflammatory cytokine production in doses of(6). In support to above study, Vitamin D found to decreaed inflammatory cytokine production from T-cell subsets implicated in asthma, according to Florida Atlantic University(7). In patient with in patients with steroid-resistant (SR) and steroid-sensitive (SS) asthma, oral administration of vitamin D, although exerted its anti-inflammatory and corticosteroid-enhancing effects in monocytes of patients with SR asthma and patients with SS asthma, the responses to corticosteroids in patients with SR asthma remained significantly lower than those in patients with SS asthma(8). Other in the study of the effect of vitamin D in severe therapy-resistant asthma (STRA) patients, showed an positive effect of 1α,25-dihydroxyvitamin D3, the active form of vitamin D in culture enhanced dexamethasone-induced IL-10 (Defective IL-10 expression causes a significantly diminished levels of anti-inflammatory interleukin (IL)-10))without marked effects on IL-13 or IL-17A production(9). Patients with severe asthma exhibited increased levels of TH17 cytokines.The study of King's College London, also suggested that 1,25(OH)2D3 inhibits TH17 cytokine production in all patients with moderate-to-severe asthma(10), enhances the frequency of Treg cells(11)and upregulates CD200 on peripheral human CD4+ T cells(12).
Taking altogether, without going into reviews, vitamin D used conjunction with other anti asthma medicine and its the active form 1α,25-dihydroxyvitamin D3, may be associated to reduced risk and treatment of asthmatic diseases. Over doses of vitamin D supplement may cause excessive calcium absorption, calcification, Urinary stones etc. please make sure to follow the guideline of the Institute of Medicine of the National Academies.

Asthma in Vitamin C points of view
The widespread of incidence of asthma over large 20 years in South East
Asian population, specially in children and aging group has caused some
concerns to the government and scientific community. It may be due to
over intake in artificial ingredients and polluted environment.
Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin, found in fresh fruits, berries and green vegetables. It is best known for its free radical scavengers activity and regenerating oxidized vitamin E for immune support.
Epidemiological studies, linking vitamin C in reduced risk and treatment of asthma have been inconclusive(a)(b)(c)(d).
The study of the effects of antioxidant nutritional status with allergic rhinitis (AR) in Korean schoolchildren aged 6-12 years, in a total of 4,554 children in Seoul, Korea, showed a positive effect of Vitamin C intake negatively associated with an increased risk of AR symptoms(1). Accordin got the Rabin Medical Center, vitamin C also enhanced the protective effect on the hyperreactive airways of patients with exercise-induced asthma (EIA)(2). Oxidative stress mediated by reactive oxygen species is known to contribute to the inflammatory process of bronchial asthma. According to Dr. Ruprai RK., in the study of the oxidative stress plasma malondialdehyde and ascorbic acid (Vitamin C) showed an oxidative imbalance in asthmatic patients and antioxidant supply may have a beneficial impact on the free radical induced injury and improvement of respiratory reserve in Asthmatics(3)(4). In Saudi asthmatic patients, King Saud University study showed to exhibit oxidative stress and defective antioxidant status and suggested these may be primary causative factor in the pathogenesis of asthma(5).
In mega doses, vitamin C in asthmatic patients also Vitamin C decreased airway hyperreactivity to methacholine, inflammatory cell numbers in brochoalveolar lavage fluid, and moderate reduction of perivascular and peribronchiolar inflammatory cell infiltration(6).

Asthma in Vitamin A points of view
The widespread of incidence of asthma over large 20 years in South East Asian population, specially in children and aging group has caused some concerns to the government and scientific community. It may be due to over intake in artificial ingredients and polluted environment.
Vitamin A is a general term of Vitamin A Retinol, retinal, beta-carotene, alpha-carotene, gamma-carotene, and beta-cryptoxanthin best known for its functions for vision health and antioxidant scavenger and essential for growth and differentiation of a number of cells and tissues.
Recommended intakes of vitamin A, according to the Institute of Medicine of the National Academies (formerly National Academy of Sciences) is 600 µg daily as extremely high doses (>9000 mg) can be toxicity as causes of dry, scaly skin, fatigue, nausea, loss of appetite, bone and joint pains, headaches, etc.
Epidemiological studies linking vitamin A in reduced risk and treatment of asthma have been inconclusive(a)(b)(c)(d)(e), but according to the University G. D'Annunzio, and Respiratory Pathophysiology Center, dietary supplementation or adequate intake of lycopene and vitamin A rich foods may be beneficial in asthmatic subjects(f).
1. Retinols
Serum vitamin A concentrations was found significantly lower in asthmatic subjects than healthy control subjects and administration of all-trans retinoic acid, ATRA dramatically attenuated airway inflammation through inhibiting Th2 and Th17 differentiation and/or functions. according to the Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine(1). ORMDL3 is a candidate gene of childhood onset asthma, and high-transcript of ORMDL3 is associated with the development of asthma. According to Nanjing Medical University, all-trans retinoic acid (ATRA) is an active metabolite of Vitamin A, reduced the risk od asthma through maintained airway epithelial integrity, inhibited asthma effector cells differentiation, modulates immune response, possibly via facilitates ORMDL3 production probable through PKA/CREB(2). Also in all-trans retinoic acid, ATRA, the Tehran University of Medical Sciences study suggested that ATRA diverted the human immune response in neutral conditions (without adding polarizing cytokines) by increasing FOXP3+ cells and decreasing RORγt+ cells(3). In rats with asthma, ATRA was found to alleviate airway hyperresponsiveness and airway remodeling possibly through decreasing the protein expression of MMP-9(4). The study at 1Inserm U700 and Université Paris 7, in a mouse model of ovalbumin (OVA)-induced T helper (Th) 2-type responses and airway remodeling, indicated a effectiveness of liposomally encapsulated ATRA (Lipo-ATRA) in exacerbates allergic immune and inflammatory responses, most likely through promoting Th2 development(5).
Unfortunately, according to Johns Hopkins University, even though animal models suggest that vitamin A deficiency affects lung development adversely and promotes airway hyperresponsiveness, and may predispose to an increased risk of asthma, but vitamin A supplementation early in life was not associated with a decreased risk of asthma in an area with chronic vitamin A deficiency(6).
2. Carotenoids (beta-carotene, alpha-carotene, gamma-carotene and beta-cryptoxanthin) Carotenoids, plant pigments, converted to vitamin A after intake, play an important role in prevention and treatment of some diseases through it antioxidant effects. In the study of the effect of vitamin intake among asthmatic subject, researchers at the Hung Kuang University, found that nutritional supplement therapy including beta carotene may improve dysregulated oxidant and antioxidant status, inflammation and immune responses, pulmonary function, and health-related quality of life in patients with mild to moderate allergic asthma(7). The John Hunter Hospital study of asthmatic subjects with airway hyper-responsiveness (AHR), indicated a reduced levels of beta-carotene and alpha-tocopherol compared with those without AHR, possibly due to impaired antioxidant defences and are thus most susceptible to the damaging effects of oxidative (8). Other researchers suggested that the imbalance of antioxidants found in asthmatic patients may be the possible causes od the disease(9) and modifying the dietary intake of carotenoids alters clinical asthma outcomes with improvements evident only through increased whole foods intake, not supplements(10)
But according to the study of Yamaguchi University, there was no significant association for asthma in Japanese youth(11) and the study of a total of 423 children from a rural area of Thailand, in a Health Interview for Asthma Control questionnaire, showed no correlation of dietary intake of carotenoids between asthmatic and non-asthmatic children(12).
Taking altogether, Using vitamin A in prevention and treatment of asthmatic patient remains controversial. According to the study in summarization of the important of vitamin A in treatment of asthma suggested that excessive intake of vitamin A may increase the risk or severity of asthma in industrialized countries whereas vitamin A deficiency continues to increase mortality from infectious diseases in developing countries(12).
But study summarized the important of vitamin A in treatment of asthma suggested that excessive intake of vitamin A may increase the risk or severity of asthma in industrialized countries whereas vitamin A deficiency continues to increase mortality from infectious diseases in developing countries(13). Overdoses can lead to toxic symptoms. Please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Skin Lightening (whitening) in herbs, Foods and Antioxidants Points of View
Kyle J. Norton(Draft Article)
Human skin pigmentation is the result of natural selection evolved to prevent damage to skin through regulation of ultraviolet radiated penetration depending to the production of melanin in the skin cells.
1. Hypo-pigment
a. Vitiligo is defined as a condition of destruction of cells that give your skin its color, causing white patches on your skin.
b. Albinism is a congenital disorder causes of complete or partial absence of pigment in the skin, hair and eyes duas a result of restriction of the skin cells from producing melanin
2.Hyper pigment is a result of over production of pigments of certain cells in the skin, causing skin darkening in some area, such as tan or brown patches, commonly on the facial skin
3. Skin discoloring is a result of discoloring your skin in specific spots or very widespread

C. The Antioxidants
C.1. Free radical scavengers
Suggestions of antioxidants, may be next potential agent in inhibition of tyrosinase activity and reduction of the melanin content in cells(22)(22a)
1. Vitamin C,
Vitamin C also known as L-ascorbic acid, is a water-soluble vitamin, found in fresh fruits, berries and green vegetables. It is best known for its free radical scavengers activity and regenerating oxidized vitamin E for immune support.
Ascorbic acid (AA) has been well known as a skin whitening agent, according to the Mahidol University, AA showed to inhibit UVA-mediated catalase (CAT) inactivation, glutathione (GSH) depletion, oxidant formation and NO production through suppression of eNOS and iNOS mRNA via its antioxidant defense(23). In the comparison of orchid extracts and 3% vitamin C derivative formulated, researchers at the Osaka National Hospital, National Hospital Organizationfound that the orchid-rich plant extracts possess efficacy similar to vitamin C derivative in whitening the skin as well as melasma and lentigo senilis on the face of Japanese women(24). Other study suggested that topical application of the composition of L(+) lactic acid supplemented with ascorbic acid (1%) produced a whitening effect and a modest preferential lightening of age spots which becomes apparent after three months, through demonstrated clinically by the test panelists, and trained clinicians, and with objective instrumental methods(25).
2. Vitamin E
Vitamin E, a fat soluble vitamin, consisting eight different variants (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) with varying levels of biological activity(26), found abundantly in corn oil, soybean oil, margarine, wheat germ oil, sunflower,safflower oils, etc. plays an important role in neurological functions and inhibition of platelet aggregation, regulation of enzymatic activity, free radical scavenger, etc..
The study in comparison of the effects of vitamin E analogues (d-alpha-, dl-alpha-, d-beta-, d-gamma-, and d-delta-tocopherols, d-alpha- and dl-alpha-tocopheryl acetates) and 2,2,5,7,8-pentamethyl-6-hydroxychroman (PMC) on melanogenesis in mouse B16 melanoma cells, showed a positive effects of d-beta-tocopherol and d-gamma-tocopherol, 2 variants of vitamin E, in skin whitening with lower skin toxicity, as well as improved skin pigmentation such as skin spots and freckles caused by UV exposure(27). According to Kobe University School of Medicine, alpha-Tocopheryl ferulate (alpha-TF), a compound containing alpha-T (a variant of vitamin E) and ferulic acid exhibited an efficient whitening effects, through suppressed melanogenesis and inhibited biological reactions induced by reactive oxygen species(28)(29).
C.2. The antioxidants
1. Resveratrol
Resveratrol is a phytochemical in the class of Stilbenoids, found abundantly in skins and seed of grape wine, nuts, peanuts, etc.
Piceatannol, a derivative of resveratrol exerted its antimelanogenic action through the combined effect of antioxidative property
and suppressed RS generation while increasing the GSH/GSSG ratio(30). According to 1Johnson &
Johnson Skin Research Center, resveratrol may be a potential cosmetic skin whitening agent through
reduced microphthalmia-associated transcription factor and tyrosinase promoter activities(31).
4. Glutathione
Glutathione (GSH), an antioxidants plays an important role in protecting cells against the free radicals
and ixidative stress, may be a potential agent in the management of hyperpigmentation(32). According
to the Chulalongkorn University, orally administered glutathione, 500 mg per day for 4 weeks, was found
effectively in reduced melanin indices consistently in all subjects(33) and may be used in the treatment
of pigmentary disorders.(34). Other study also indicated the effectiveness of glutathione in regulatesing
melanocytotoxicity and depigmenting potency of N-acetyl-4-S-CAP in black and yellow mice(35)
Taken altogether, although with scattered data, the herbs, foods, and antioxidants indicated above may potent in exhibition of the depigment and lightening (whitening) effects, through inhibited, and biological reactions induced by reactive oxygen species and suppressed melanogenesis and intracellular tyrosinase activity.

Other study of the effects of tea polysaccharides (TPS) and polyphenols (TPP) on skin, showed to exhibit the moisture absorption and retention, sunscreen, promoting the proliferation of fibroblast cells, and tyrosinase inhibitory effect(17).
3. Cinnamon
Cinnamon is a spice derived from the inner bark of tree, native to South East Asia, of over 300 species of the genus Cinnamomum, belonging to the family Lauraceae.. The herb has been use in herbal and traditional medicine as anti-fungal and bacteria level to improve reproductive organ, prevent flatulence and intestinal cramping, treat indigestion, diarrhea, bad breath, headache, migraine, etc.
The essential oil extracted from Cinnamomum cassia Presl (CC-EO) and its major component, cinnamaldehyde, possess potent anti-tyrosinase and anti-melanogenic activities through theirs antioxidant activities and may be a potential source of skin-whitening agents(18)
4. Red Onion((Allium cepa)
The onion is a plants in the genus Allium, belongs to the family Alliaceae, a close relation of garlic. It It is often called the "king of vegetables" because of its pungent taste and found in a large number of recipes and preparations spanning almost the totality of the world's cultures. Depending on the variety, an onion can be sharp, spicy, tangy, pungent, mild or sweet.
Quercetin 4'-O-β-D-glucopyranoside was isolated from the dried skin of A. cepa. showed tyrosinase inhibitory activity as it possesses ingredients with potential for skin-whitening cosmetics(19).
5. Ginger
Ginger (Zingiber officinale) or ginger root is the genus Zingiber, belonging to the family Zingiberaceae, native to Tamil. It has been used in traditional and Chinese medicine to treat dyspepsia, gastroparesis, constipation, edema, difficult urination, colic, etc.
[6]-Gingerol, an active component of ginger not only (25-100 µM) effectively suppressed murine tyrosinase activity and decreases the amount of melanin, but also decreased the intracellular reactive oxygen species (ROS) level in a dose-dependent manner(20). the University of Malaya, in the study of the effects of [8]-Gingerol, another active component of Zinger, found that [8]-gingerol (5-100μM) not only effectively suppressed intracellular tyrosinase activity and decreased the amount of melanin in B16F10 and B16F1 cells, but also fectively decreased intracellular reactive species (RS) and reactive oxygen species (ROS) levels at the same dose manner, probably through down-regulation of both mitogen-activated protein kinases (MAPK) and protein kinase A (PKA) signaling pathways or through its antioxidant properties(21).
6. Pomegranate
Pomegranates is a fruit-bearing small tree, genus Punica, belonging to family Lythraceae, native to Iran but has been cultivated in Asian since ancient time.
Pomegranate extract (PE) containing 90% ellagic acid administered orally, inhibited UV-induced skin pigmentation on the back of brownish guinea pigs with skin-whitening effect was similar between guinea pigs fed with PE and those fed with L-ascorbic acid(21a) and moderate effect in human skin(21b).
C. The Antioxidants
C.1. Free radical scavengers
Suggestions of antioxidants, may be next potential agent in inhibition of tyrosinase activity and reduction of the melanin content in cells(22)(22a)
1. Vitamin C,
Vitamin C also known as L-ascorbic acid, is a water-soluble vitamin, found in fresh fruits, berries and green vegetables. It is best known for its free radical scavengers activity and regenerating oxidized vitamin E for immune support.
Ascorbic acid (AA) has been well known as a skin whitening agent, according to the Mahidol University, AA showed to inhibit UVA-mediated catalase (CAT) inactivation, glutathione (GSH) depletion, oxidant formation and NO production through suppression of eNOS and iNOS mRNA via its antioxidant defense(23). In the comparison of orchid extracts and 3% vitamin C derivative formulated, researchers at the Osaka National Hospital, National Hospital Organizationfound that the orchid-rich plant extracts possess efficacy similar to vitamin C derivative in whitening the skin as well as melasma and lentigo senilis on the face of Japanese women(24). Other study suggested that topical application of the composition of L(+) lactic acid supplemented with ascorbic acid (1%) produced a whitening effect and a modest preferential lightening of age spots which becomes apparent after three months, through demonstrated clinically by the test panelists, and trained clinicians, and with objective instrumental methods(25).
2. Vitamin E
Vitamin E, a fat soluble vitamin, consisting eight different variants (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) with varying levels of biological activity(26), found abundantly in corn oil, soybean oil, margarine, wheat germ oil, sunflower,safflower oils, etc. plays an important role in neurological functions and inhibition of platelet aggregation, regulation of enzymatic activity, free radical scavenger, etc..
The study in comparison of the effects of vitamin E analogues (d-alpha-, dl-alpha-, d-beta-, d-gamma-, and d-delta-tocopherols, d-alpha- and dl-alpha-tocopheryl acetates) and 2,2,5,7,8-pentamethyl-6-hydroxychroman (PMC) on melanogenesis in mouse B16 melanoma cells, showed a positive effects of d-beta-tocopherol and d-gamma-tocopherol, 2 variants of vitamin E, in skin whitening with lower skin toxicity, as well as improved skin pigmentation such as skin spots and freckles caused by UV exposure(27). According to Kobe University School of Medicine, alpha-Tocopheryl ferulate (alpha-TF), a compound containing alpha-T (a variant of vitamin E) and ferulic acid exhibited an efficient whitening effects, through suppressed melanogenesis and inhibited biological reactions induced by reactive oxygen species(28)(29).
C.2. The antioxidants
1. Resveratrol
Resveratrol is a phytochemical in the class of Stilbenoids, found abundantly in skins and seed of grape wine, nuts, peanuts, etc.
Piceatannol, a derivative of resveratrol exerted its antimelanogenic action through the combined effect of antioxidative property
and suppressed RS generation while increasing the GSH/GSSG ratio(30). According to 1Johnson &
Johnson Skin Research Center, resveratrol may be a potential cosmetic skin whitening agent through
reduced microphthalmia-associated transcription factor and tyrosinase promoter activities(31).
4. Glutathione
Glutathione (GSH), an antioxidants plays an important role in protecting cells against the free radicals
and ixidative stress, may be a potential agent in the management of hyperpigmentation(32). According
to the Chulalongkorn University, orally administered glutathione, 500 mg per day for 4 weeks, was found
effectively in reduced melanin indices consistently in all subjects(33) and may be used in the treatment
of pigmentary disorders.(34). Other study also indicated the effectiveness of glutathione in regulatesing
melanocytotoxicity and depigmenting potency of N-acetyl-4-S-CAP in black and yellow mice(35)
Taken altogether, although with scattered data, the herbs, foods, and antioxidants indicated above may potent in exhibition of the depigment and lightening (whitening) effects, through inhibited, and biological reactions induced by reactive oxygen species and suppressed melanogenesis and intracellular tyrosinase activity.
