Polygonatum species, commonly known as Solomon's Seal, have a long history of use in traditional Chinese medicine (TCM). In TCM, Polygonatum (especially Polygonatum sibiricum and Polygonatum odoratum) is considered a tonic herb that nourishes yin, moistens dryness, and is used in formulas intended to address symptoms such as dizziness, fatigue, and weakness. The rationale is often based on the concept of “yin deficiency,” which is thought to lead to symptoms like dizziness and lightheadedness. Classical texts, such as the “Shennong Bencao Jing,” mention Polygonatum as a restorative herb, and it is commonly found in multi-herb formulas that target age-related complaints, weakness, and vertigo-like symptoms.

However, there is little to no modern scientific research specifically validating the efficacy of Polygonatum for treating dizziness. Most available studies focus on its potential effects on blood sugar, immunity, or anti-aging, rather than its impact on vertigo or balance disorders. Thus, the evidence supporting its use for dizziness is primarily based on traditional medical systems and not on contemporary clinical trials or pharmacological studies. As such, while Polygonatum is traditionally used for dizziness, this use remains supported mainly by historical practice rather than modern scientific validation.
