Rating (out of 5): 1

Cornus, typically referring to Cornus officinalis or the Japanese cornel dogwood, is used in traditional Chinese medicine (TCM) and other East Asian herbal systems. In TCM, Cornus (commonly called "Shan Zhu Yu") is thought to "tonify the liver and kidney," and is frequently included in herbal formulas for symptoms associated with lower back pain, especially when categorized as "kidney deficiency." The traditional rationale links the health of the kidneys with the strength of the lower back, a concept central to TCM theory but not directly supported by modern biomedical science.

However, there is little high-quality scientific evidence to support the efficacy of Cornus for treating backache specifically. The available clinical and pharmacological studies focus more on its potential antioxidant, anti-inflammatory, and neuroprotective properties, which are not directly tied to backache in controlled trials. Most references to its use for back pain are found in classical herbal texts and ethnobotanical reports, rather than contemporary clinical research.

In summary, the use of Cornus for backache is justified by traditional practice rather than robust scientific validation, and the evidence supporting its effectiveness for this indication is limited.
