1. As a medicinal plant, Asarum was first mentioned in "Shen Nong's Materia Medica". Traditional Chinese medicine believes that it is warm in nature, pungent in taste, slightly toxic, and has the functions of dispersing cold, dispelling wind, relieving pain, and warming the lungs. It has the functions of drinking and clearing the orifices, and can be clinically used to treat symptoms of wind-cold syndrome, rheumatic arthralgia, headache, toothache and other disease symptoms.

2. Sedation and analgesia. In vitro animal studies have shown that asarum has an inhibitory effect on the central nervous system of the body. At the same time, the methyl eugenol in the volatile oil also has a certain local anesthetic effect. This is one of the main reasons why asarum has analgesic effects.

3. Dispel cold and wind. Studies have shown that Asarum’s effect of dispersing cold and dispelling wind is related to the higenamine it contains. Higenamine can help improve the body’s metabolic function. It also has the effects of strengthening the heart, dilating blood vessels, and relaxing smooth muscles. This is consistent with the pharmacological basis of anti-cold medicine.
