Pharmacological Action

1. Anti-tumor effect in vitro (equivalent to 6 g/ml of crude drug) on ​​acute lymphocytic, granulocytic,

It has a strong inhibitory effect on monocytic and chronic myeloid tumor cells (methylene blue test tube method); measured by Warburg respirator, the inhibitory effect on the former two is also strong. The extract was used in experimental treatment of S-180 and Ehrlich ascites carcinoma in mice, and Yoshida sarcoma in rats, but had no obvious anti-cancer effect. 0.5-1 gram of crude drug/ml had inhibitory effects on Yoshida sarcoma and Ehrlich ascites carcinoma in vitro (methylene blue test tube method), but the authors believe that this is non-specific.

2. Antibacterial and anti-inflammatory effects: The antibacterial effect in vitro is not significant , and it only has a weak effect on Staphylococcus aureus and Shigella dysenteriae. The effects of the decoction on the phagocytic function of the reticuloendothelial system and the phagocytic activity of leukocytes in vivo and in vitro in normal and artificial appendicitis rabbits were observed. It was believed that its anti-inflammatory effect was due to factors such as stimulating the proliferation of the reticuloendothelial system and enhancing the activity of phagocytes.
