Essential oil Anise may have a potential and substantial effect in reduced risk and progression and treatment of viral infectious diseases, some scientists suggested.
Anise is a flowering plant of the species of Pimpinella anisum, genus Pimpinella, belongings to the family Apiaceae native to Egypt and the Mediterranean region, used in traditional herbal medicine as a fragrance in soaps, oils, and mouth fresheners and stomachic, anti-septic, anti-spasmodic, ....
Chemical constituents
Anethole, D-pinene, I-phellandrene, Alpha-terpineol, Safrol, Methyl chavicol, Resin, Shikimic acid, etc.
In the investigation of the effects of several essential oils, including Anise in against expression of herpes simplex virus type 2 (HSV-2) in vitro on RC-37 cells, using a plaque reduction assay, researchers found that application of essential oil of concentrations (IC50) at doses of 0.016%, 0.0075%, 0.007%, 0.004%, 0.003%, and 0.0015% demonstrated significant effects linearly in ameliorate persistent infection spreading of sexually transmitted disease of the virus.
A maximum dose, essential oil of Ansie without inducing cytotoxicity to healthy cells exerted an inhibitory effect against different stages during the viral infectious cycle and plaque formation by more than 90%.
Interestingly, all essential oils displayed no inhibitory effect cells prior to infection with HSV-2 or after the adsorption period.
These results suggested that injection of Ansis essential oil can only affect HSV-2 after penetrating into the viral envelope.
In compared to the inhibitory effects of all essential oil, Anise exhibited a less selectivity activity in compared to essential oil isolated from chamomile.
Further demonstration of Anise antiviral activity, using 3 antiviral and immunostimulating substances (LC1, LC2 and LC3) isolated from a hot water extract of seeds of Pimpinella anisum by combination of anion-exchange, gel filtration, and hydrophobic interaction column chromatographies researchers at the University of Toyama suggested that the lignin and carbohydrate molecules(CLs) bonded physically or chemically with each other of LC1, LC2 and LC3 exerted a significantly antiviral activities in reduced expression of herpes simplex virus types 1 and 2 (HSV-1 and -2), human cytomegalovirus (HCMV) and measles virus.
Moreover, the application of all LCs substances inhibited the virus induced-adsorption to the host cell surface by direct inactivating the virus's penetration through enhanced nitric oxide (NO) production by inducing iNOS mRNA and protein expression in RAW 264.7 murine macrophage cells in response to viral attacks.
These result of rival inhibitory effect of Anise LCs substances not only prevented virus in alternated the healthy cells DNA in the initiated infectious cell proliferation but also inhibited production of interleukin 1 beta (IL-1β) and interleukin 10 caused by overreaction of immune response in elevated expression of pro-inflammatory cytokines in induction of healthy cell damage and cell apoptosis.
The above differentiation was supported by the study in the evaluated the effect of limonene, the major bioactive compound found in Fennel and Ansie in inhibited risk and progression and treatment of dengue, a potentially fatal mosquito-borne infection of 50 million cases per year with 2.5 billion people who are vulnerable to the disease.
According to the results, the application of essential oil using WHO procedures displayed a substantial effect against third instar larvae of Ae. aegypti for 24 h.
More specifically, the result of inhibition of over 99% of tested virus was attributed to major constituent (-)-limonene at lethal concentrations LC50, C90, and LC99.
Taken together, Anise and its major bioactive monoterpenes may be considered as a possessed potency as functional food ingredients against infectious diseases caused by viral invasion.
