Capillary Artemisia (Artemisia capillaris), also known as Yin Chen Hao in traditional Chinese medicine (TCM), has a long history of use primarily for liver and gallbladder ailments, such as jaundice and hepatitis. The use of Capillary Artemisia for backache is not widely documented in scientific literature, nor is it a common indication in major ethnobotanical references. However, some traditional Chinese medicine formulas that target systemic inflammation or promote "qi" circulation may include Capillary Artemisia and, by extension, might be used for musculoskeletal complaints like backache in certain folk practices.

Scientific studies on Artemisia capillaris focus on its hepatoprotective, anti-inflammatory, and antioxidant properties, but there is a lack of direct clinical research supporting its effectiveness for backache specifically. The only support for its use in backache comes from traditional practices where herbs are used in complex formulas to address underlying imbalances believed to cause pain, rather than the symptom of backache itself. Consequently, the evidence for Capillary Artemisia’s use in backache is weak and primarily based on tradition rather than robust clinical validation.
