Thymol. Thymol (also known as 2-isopropyl-5-methylphenol, IPMP) is a natural monoterpene phenol derivative of cymene, C10H14O, isomeric with carvacrol, found in oil of thyme, and extracted from Thymus vulgaris (common thyme) and various other kinds of plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties.
Thymol also provides the distinctive, strong flavor of the culinary herb thyme, also produced from T. vulgaris. Biological activity[edit] Thymol has been shown to act as a positive allosteric modulator of GABAA in vitro.[8] Thymol is chemically related to the anesthetic propofol.

Quercetin has been used in Chinese folk medicine for centuries to treat type 2 diabetes, a fact that is leading contemporary researchers to study its effects in preventing metabolic syndrome and obesity. Quercetin is included in a group of plant pigments known as flavonoids that are powerful antioxidants, substances that target harmful particles in your body called free radicals, according to the University of Maryland Health Center. Quercetin is found in high concentrations in apples, onions, citrus fruits, parsley, tea and red wine, and in moderately high levels in olive oil, grapes, dark cherries, dark berries such as blueberries, blackberries, and bilberries, and in other fruits and vegetables.
