① Effect on experimental arthritis in rats: The volatile sake and total alkaloids of Aristolochia have obvious preventive effect on albumin arthritis in rats, but the non-alkaloid part is ineffective. The cold soaking agent is precipitated with ethanol 1 time, which is effective for albumin arthritis and formaldehyde arthritis, but it will lose its effect if it is precipitated twice and autoclaved.

② Detumescence and analgesic effects The whole grass powder mixed in the feed has obvious inhibitory effect on Ehrlich ascites carcinoma and the total cell number of ascites, and also has obvious effect on the subcutaneous tumor of Ehrlich ascites carcinoma. The decoction is also effective by oral administration.

After preliminary analysis, it seems that the effective components are soluble in water and ethanol, insoluble in chloroform, and will not be destroyed by heating.
