Ginsenoside rh2 is one of the extracts of the Chinese herb ginseng, which has the effect of improving the body’s ability to fight diseases. Modern pharmacological analysis of ginseng shows that the main component of ginseng, a great tonic herb, is ginsenoside, of which there are more than 30 kinds of classifications, and ginsenoside rh2 is only one of them. Nowadays, ginsenoside rh2 is mostly taken directly into health products to improve the body’s immunity and inhibit the growth of tumor cells, and it has inhibitory effects on many kinds of tumors, such as melanocytoma, liver cancer, breast cancer, bone cancer, colon cancer and lung cancer. However, the role of health supplements cannot completely replace drugs, so it is recommended that the application of oral health supplements should be considered on the basis of regular hospital treatment.
