Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Ligusticum wallichii (commonly known as Chuanxiong or Szechuan lovage) is a well-known herb in Traditional Chinese Medicine (TCM). Its primary traditional uses include promoting blood circulation, alleviating pain, and dispelling wind to relieve headaches. While it is not one of the first-line herbs for treating nausea and vomiting, it appears in some classical and modern herbal formulas intended for addressing these symptoms, usually as an adjunct to harmonize the formula or address underlying causes, such as stagnation.

Historical texts and TCM practitioners sometimes recommend Ligusticum wallichii for nausea and vomiting, particularly when these symptoms are believed to stem from "blood stasis" or internal wind. However, the herb is more frequently associated with treating headaches, menstrual disorders, and cardiovascular complaints. The evidence for its effectiveness in nausea and vomiting comes primarily from traditional usage patterns and anecdotal clinical experience, rather than controlled scientific studies.

There is limited scientific research specifically investigating Ligusticum wallichii for nausea and vomiting. Most pharmacological studies focus on its anti-inflammatory, neuroprotective, and cardiovascular effects. Therefore, while its use for nausea and vomiting can be justified on traditional grounds, scientific validation is lacking, resulting in a moderate evidence rating based mainly on historical usage rather than clinical research.
