This invention is to provide multiple specific inhibitors of cytochrome P450 isozyme CYP2C9. These inhibitors can be derived from any combinations with the following compounds including: Tamarixetin, Formononetin, isoliquritigenin, Phloretin, luteolin, Quercitrin, quercetin, myricetin, Wongonin, Puerarin, Genistein, Nordihydroguaiaretic acid, Narigenin, Capillarisin, Chrysin, Fisefin, eriodictyol, 6-Gingerol, Isorhamneti, isoquercitrin, Morin, (+)-Taxifolin, isovitexin, 3-Phenylpropyl Acetate, Oleanolic acid, ursolic acid, β-Myrcene, cinnamic acid, Luteolin-7-Glucoside, Liquiritin, (+) Limonene, Homoorientin, Swertiamarin, Embelin, Daidzein, Poncirin, (−)-Epicatechin, ergosterol. These natural products can be used to enhance the bioavailability of therapeutic agents (drugs). 1. A method for enhancing the bioavailability of a therapeutic agent in a patient comprising:administering a pharmaceutically effect amount of CYP2C9 inhibitor and a pharmaceutically viable drug extensively metabolized by CYP2C9 to said patient in need thereof,wherein said CYP2C9 inhibitor which is selected at least one compound of the following group consisting of Tamarixetin, Formononetin, luteolin, Quercitrin, myricetin, Wongonin, Puerarin, Genistein, Narigenin, Capillarisin, Chrysin, Fisefin, eriodictyol, Isorhamnetin, isoquercitrin, Morin, (+)-Taxifolin, isovitexin, Luteolin-7-Glucoside, Daidzein, and Poncirin; andwherein said pharmaceutically viable drug which is one selected from the group consisting of tolbutamide, diclofenac, warfarin, phenytoin, torsemide, fluvastatin, losartan, celecoxib, meloxicam, isoniazide, valproic acid, ibuprofen, carvedilol, naproxen, and ondansetron.2. A method for enhancing the bioavailability of a therapeutic agent in a patient comprising:administering a CYP2C9 inhibitor and a pharmaceutically viable drug extensively metabolized by CYP2C9 to said patient in need thereof,wherein said CYP2C9 inhibitor is Phloretin; andwherein said pharmaceutically viable drug ...
