Rehmannia glutinosa, known as "Sheng Di Huang" in Traditional Chinese Medicine (TCM), is primarily used in traditional contexts to address skin issues such as dryness and flakiness. In TCM, Rehmannia is believed to "nourish Yin" and "cool the blood," both of which are thought to help with conditions characterized by dryness, itching, or inflammation of the skin. Historical texts describe its use in formulas like "Liu Wei Di Huang Wan," which is prescribed for symptoms associated with Yin deficiency, including dry skin. While Rehmannia is not a direct topical treatment, it is used internally to address underlying imbalances believed to manifest as skin complaints.

Scientific research into Rehmannia's effects on skin health is limited, and there are few modern clinical trials specifically examining its efficacy in treating dry or flaky skin. Some laboratory and animal studies suggest anti-inflammatory and antioxidant properties, which could theoretically benefit skin health, but direct evidence for its use in treating dryness or flakiness is lacking. Therefore, its use for this condition remains grounded in traditional practice rather than robust scientific validation. Individuals considering its use should consult healthcare professionals, especially since TCM approaches skin issues holistically and may combine Rehmannia with other herbs.
