Polygonatum (commonly known as Solomon's Seal or Huang Jing in Traditional Chinese Medicine) has been historically used in various Asian medical systems. In Traditional Chinese Medicine (TCM), Polygonatum species are considered to nourish the yin, moisten dryness, and tonify the spleen and lungs. Dizziness is often interpreted in TCM theory as a manifestation of deficiencies in the spleen, kidney, or liver, or as a result of "yin" deficiency and "internal wind." Polygonatum is sometimes included in herbal formulas aimed at replenishing qi and yin, which, according to TCM, may help address symptoms like dizziness, fatigue, and weakness.

However, there is limited clinical or pharmacological research directly investigating Polygonatum for the treatment of dizziness in the biomedical sense. Most of the available scientific literature focuses on its possible anti-diabetic, immunomodulatory, and antioxidant effects, rather than any direct impact on vertigo or vestibular disorders. The use for dizziness, therefore, is primarily justified by traditional theory and historical use rather than rigorous scientific validation.

In summary, Polygonatum is traditionally used within the framework of TCM for conditions that may include dizziness, but scientific evidence directly supporting its efficacy for this specific symptom is minimal.
