Asarum is a traditional Chinese medicinal herb, derived from the dried roots and rhizomes of plants in the Aristolochiaceae family, including Asarum heterotropoides Fr. Schmidt var. mandshuricum (Maxim.) Kitag., Asarum sieboldii Miq., or Asarum sinensis. It has a pungent and warm nature and enters the lung and kidney meridians. Its main functions and effects include dispelling wind and cold, promoting water movement, opening the orifices, relieving pain, warming the lungs, and resolving phlegm. Detailed functions are as follows:
1. Dispelling Wind and Cold: Asarum can be used to treat symptoms such as common cold, headache, and body pain caused by wind-cold invasion.
2. Promoting Water Movement: It has a diuretic effect and can be used to treat edema and phlegm-fluid retention.
3. Opening the Orifices: It helps relieve nasal congestion, nasal polyps (sinusitis), and mouth ulcers.
4. Relieving Pain: It is suitable for treating pain symptoms such as headaches, toothaches, and joint pain.
5. Warming the Lungs and Resolving Phlegm: It is effective in treating symptoms such as cough caused by cold in the lungs and excessive clear phlegm.
In daily use, Asarum is typically taken internally as a decoction and applied externally in appropriate amounts by grinding into powder for nasal insufflation, ear plugging, umbilical application, or oral rinsing with its decoction. However, Asarum has certain toxicity, so dosage should be carefully controlled. If any discomfort occurs, medical attention should be sought immediately.
