Gingerol ([6]-gingerol) is a phenolic phytochemical compound found in fresh ginger that activates spice receptors on the tongue. It is normally found as a pungent yellow oil in the ginger rhizome, but can also form a low-melting crystalline solid. This chemical compound is found in all members of the Zingiberaceae family and is high in concentrations in the grains of paradise as well as an African Ginger species. Cooking ginger transforms gingerol via a reverse aldol reaction into zingerone, which is less pungent and has a spicy-sweet aroma. When ginger is dried or mildly heated, gingerol undergoes a dehydration reaction forming shogaols, which are about twice as pungent as gingerol. This explains why dried ginger is more pungent than fresh ginger. Ginger also contains [8]-gingerol, [10]-gingerol, and [12]-gingerol, collectively deemed gingerols. Physiological potential In a pre-clinical meta-analysis of gingerol compounds anticancer, anti-inflammatory, anti-fungal, antioxidant, neuroprotective and gastroprotective properties were reported, which include studies in-vitro and in-vivo. A few in-vivo studies have proposed that gingerols facilitate healthy glucose regulation for diabetics. Many studies have been around the effects of gingerols on a wide range of cancers including leukemia, prostate, breast, skin, ovarian, lung, pancreatic and colorectal. There has not been much clinical testing to observe gingerols physiological impacts in humans. While many of the chemical mechanisms associated with the effects of gingerols on cells have been thoroughly studied, few have been in a clinical setting. This is due to the high variability in natural phytochemicals and the lack of efficacy in research. Most herbal medicine, which include gingerols, are under the restrictions of the Food and Drug Administration in the United States and experimental methods have not held up to scrutiny which has decreased the value in phytochemical research. Herbal medicine is untested for quality assurance, potency and effectiveness in clinical settings due to a lack of funding in eastern medical research. Most research on [6]-Gingerol has been on either mouse subjects (in-vivo) or on cultured human tissue (in-vitro) and may be used in the future to discuss possible applications for multi-target disease control. An investigation scrutinizing gingerol's anti-fungal capabilities remarked that an African species of ginger tested higher in both gingerol and shogaol compounds than the more commonly cultivated Indonesian relative. When tested for the anti-fungal properties the African ginger combated against 13 human pathogens and was three times more effective than the commercial Indonesian counterpart. It is thought that
