Polygonatum kingianum, commonly known as King Solomon's Seal, is a traditional herb widely used in Chinese medicine. In traditional Chinese medicine (TCM), it is considered a tonic herb with purported benefits for nourishing the yin, moistening dryness, and supporting the kidneys. The kidneys, according to TCM theory, are closely associated with the health of bones and the skeletal system. Thus, Polygonatum kingianum is used in formulations intended to strengthen bones and support skeletal health, particularly in conditions associated with aging or chronic deficiency.

However, the direct scientific evidence supporting Polygonatum kingianum for bone health is limited. While some laboratory studies have investigated its bioactive compounds for antioxidant and anti-inflammatory activities, as well as general health benefits, there is insufficient robust clinical research demonstrating a clear effect on bone density or bone healing in humans. The traditional use for skeletal support is based primarily on the theoretical framework of TCM rather than modern biomedical mechanisms or clinical trials.

In summary, Polygonatum kingianum is traditionally used to support the skeletal system, but current scientific evidence validating its efficacy for this purpose remains weak.
