Solomon's seal (Polygonatum spp.) has a long history of use in traditional herbal medicine, particularly in Eastern and Western herbal traditions. Historically, the rhizome of Solomon's seal has been used to support joint health, reduce inflammation, and aid in the healing of connective tissues, ligaments, and tendons. Some traditional sources describe its use for treating bruises, sprains, and musculoskeletal discomfort, suggesting that it supports the muscles and related structures indirectly through these effects.

The primary rationale for its use stems from anecdotal and empirical evidence in folk medicine rather than modern scientific validation. There are very few clinical studies directly investigating Solomon's seal for muscle health or function. Most available research focuses on its anti-inflammatory, antioxidant, and adaptogenic properties, which could theoretically benefit the musculoskeletal system, but this link is largely speculative and has not been robustly demonstrated in controlled scientific studies.

In summary, the use of Solomon's seal for supporting the muscles body system is primarily justified by traditional practice and historical usage rather than scientific validation. While it may have supportive roles in traditional healing regarding connective tissue and joint health, direct evidence for its effectiveness in muscle support specifically remains limited.
