Chai Hu Bupleurum Root, Ⅲ
Chai Hu Bupleurum has shown itself to have many anti-cancer properties.
Many studies have been done, both in vitro (test tube) and in vivo (living organism) on various types of cancer demonstrating its ability to hinder cancer in multiple ways.

In the test tube, Chai Hu Bupleurum root was able to kill living cancer cells, including lung adenocarcinoma, as well as breast, colon, liver and ovarian cancer.4, 5, 6, 7

Extracts of Chai Hu Bupleurum, specifically from the variety B. scorzonerifolium, showed a dose-dependent ability to stop tumor cell growth of lung adenocarcinoma into surrounding tissues through apoptosis, which is the normal process a cell undertakes from life to death.8, 9, 10
Gastric ulcers were induced in animals. The active ingredients in Chai Hu Bupleurum were found to reduce the effect of these ulcers and increase healing rates. In fact, the effects of these active ingredients were comparable to sucralfate, which is a prescription medication used to treat peptic ulcer disease.1, 11, 12, 13
What’s also extremely interesting is that an ethanol extract of the aerial parts of Chai Hu Bupleurum root were discovered to have an anti- H. pylori action. H. pylori (Helicobacter pylori) is a stomach bacteria known to cause inflammation of the inner lining of the stomach (gastritis).14 H. pylori is also known to be a major cause of peptic ulcer disease, and also has been linked in the development of stomach cancer.
