7. The composition of claim 1 in combination with another medicament or with one or more pharmaceutical acceptable carriers for the lowering of blood lipid levels.
8. The composition of claim 7 , wherein the carrier is a food or a beverage.
9. A method of lowering the blood lipid levels in a patient in need of such lowering, comprising administering to the patient an effective amount of the composition according to claim 1 .
10. The method of claim 9 , wherein the composition is administered orally.
11. The method of claim 9 , wherein the composition is orally administered to the patient in a food or beverage.
12. The method of claim 9 , wherein the blood lipid levels that are lowered comprise triglyceride levels.
13. The method of claim 9 , wherein the blood lipid levels that are lowered comprise low-density-lipoprotein cholesterol levels.
14. The method of claim 9 , wherein the blood lipid levels that are lowered comprise total cholesterol levels.
15. The method of claim 9 , wherein the mammal is a human.
16. The composition of claim 1 , wherein the HL is from Coptis chinensis Franch.
17. The composition of claim 1 , wherein the KDC is from Ilex kudingcha C. J. Tseng ( Aquifoliaceae ).
18. The composition of claim 1 , wherein the blood lipids are triglycerides, low-density-lipoprotein cholesterol or total cholesterol.
19. The composition of claim 1 , wherein the method for obtaining the Ku Ding Cha extract comprises extraction of Ilex kudingcha with ethanol to obtain a first extract, drying the first extract to obtain a dried extract, dissolving the dried extract in water to provide a resuspended extract, extracting the resuspended extract with ethyl acetate and separating the ethyl acetate phase to provide the Ku Ding Cha extract.
20. The composition of claim 1 , wherein the method for obtaining the Ku Ding Cha extract comprises extraction of Ilex kudingcha with ethanol to obtain a first extract, drying the first extract to obtain a dried extract, dissolving the dried extract in water to provide a resuspended extract, extracting the resuspended extract with ethyl acetate and separating the aqueous phase to provide the Ku Ding Cha extract.
21. The composition of claim 1 , wherein the Huanglian extract is obtained by a method comprising extraction of Coptis chinensis with water and the Ku Ding Cha extract is obtained by a method comprising extraction of Ilex kudingcha with water.
22. The composition of claim 1 , wherein the HL extract is obtained by a method comprising extraction of Coptis chinensis with ethanol and the Ku Ding Cha extract is obtained by a method comprising extraction of Ilex kudingcha with ethanol.
23. The composition of claim 1 , wherein the Huanglian extract is obtained by a method comprising extraction of Coptis chinensis with ethanol and the Ku Ding Cha extract is obtained by a method comprising extraction of Ilex kudingcha with ethyl acetate.
24. The composition of claim 1 , wherein the Huanglian extract is obtained by a method comprising extraction of Coptis chinensis with ethanol, and wherein the Ku Ding Cha extract is obtained by a method comprising extraction of Ilex kudingcha with ethanol to obtain a first extract, drying the first extract to obtain a dried extract, dissolving the dried extract in water to provide a resuspended extract, extracting the resuspended extract with ethyl acetate and separating the ethyl acetate phase to provide the Ku Ding Cha extract.
