Siler root, known as Fang Feng in Traditional Chinese Medicine (TCM) and derived from the plant Saposhnikovia divaricata, has a long history of use in East Asian herbal medicine. It is typically used to "expel wind," "relieve the exterior," and treat symptoms such as headaches, body aches, and chills. In the context of dizziness, siler root may be included in multi-herb formulas targeting patterns like "wind invasion," which in TCM theory can manifest as dizziness or vertigo. However, these conceptual frameworks are rooted in traditional medical philosophy and not in modern biomedical understanding.

From a scientific perspective, there is currently insufficient evidence to directly support the use of siler root for treating dizziness. There are few, if any, clinical studies specifically investigating its efficacy for this symptom. Some laboratory research has explored the anti-inflammatory and immunomodulatory effects of siler root, but these do not establish a clear mechanism for alleviating dizziness. Overall, while siler root is traditionally included in remedies for symptoms that may include dizziness, this use is not supported by robust clinical trials or pharmacological data. As such, the rating for evidence is low, reflecting reliance on historical practice rather than scientific validation.
