Rating (out of 5): 1

Fang-Feng (Saposhnikovia divaricata), also known as Siler root, is a well-known herb in Traditional Chinese Medicine (TCM). Its use is primarily documented for dispelling "wind," alleviating exterior syndromes such as headaches, body aches, and certain types of tremors and convulsions (often interpreted in TCM as manifestations of "wind" invasion). In classical TCM texts, Fang-Feng is rarely, if ever, referenced specifically for "nervousness" as defined in modern terms (e.g., anxiety, restlessness, or emotional agitation). However, Fang-Feng appears in some multi-herb TCM formulas that are occasionally used for symptoms overlapping with nervousness, such as restlessness or spasms, though this is secondary to its main indications. There is minimal direct historical evidence supporting its solo use for nervousness, and the rationale is rooted more in the broad TCM theory of wind affecting the mind or spirit. Scientific evidence is lacking; no clinical trials or pharmacological studies directly support Fang-Feng's efficacy for treating nervousness or anxiety in the Western biomedical sense. Overall, the connection between Fang-Feng and the treatment of nervousness is tenuous and based predominantly on traditional conceptual frameworks rather than robust historical records or scientific validation.
