Chinese Silkvine (Periploca sepium) is an herb traditionally used in Chinese medicine, known as xiānɡ jiā pí (香加皮). Its primary uses in classical Chinese herbalism are to dispel wind and dampness, strengthen tendons and bones, and reduce swelling and pain, particularly in cases of rheumatic conditions or arthritis. While it is not a major remedy for headaches in the traditional sense, it may be included in compound formulas for conditions manifesting with headache when these are believed to stem from wind-damp invasion or associated musculoskeletal pain, according to traditional Chinese medicine (TCM) theory.

There is some documentation in TCM literature that Chinese Silkvine can be used for symptoms such as headaches, especially if these are linked to musculoskeletal tension or wind-damp-related disorders. However, these uses are rooted in traditional practice rather than scientific validation. There is currently insufficient modern clinical research or pharmacological evidence to support the efficacy or mechanism of Chinese Silkvine specifically for general headache relief. Most contemporary references to its use for headache are extrapolated from its broader application for pain and musculoskeletal discomfort in TCM.

In summary, the use of Chinese Silkvine for headache is primarily justified by traditional use within the specific context of TCM diagnosis and not by robust scientific studies.
