In Traditional Chinese Medicine (TCM), Golden Six Capsules can replenish Yin due to the Yin insufficiency of the kidney. The kidney is the innate foundation of all organs with respect to the Yin-Yang principles, Qi essence etc. When the kidney is diminished functionally, many other organs show malfunctions. It is thus vitally important to maintain the kidney in a good state. This explains why many symptoms seemingly unrelated to the kidney may be relieved by restoring the kidney Yin-Yang.While modern biomedical studies have yet to reveal the basis of the kidney Yin-Yang and how Golden Six Capsules works, some researches have found that Golden Six Capsules can increase the number of T lymphocytes and regulate the production of cytokines^{1, 2} and thus Golden Six Capsules may adjust the immune function of our body. Golden Six Capsules can also increase the production of sex hormones and of adrenal cortical hormones that have anti-inflammatory function in animal studies³. Moreover, Golden Six Capsules can reduce blood sugar levels and increase the activity of superoxide dismutase (SOD) in the diabetes rat model⁴. SOD is a key enzyme for eliminating free radicals in the body and its enhanced function prolongs lifespan in animal studies.

Golden Six Capsules is indicated in China Pharmacopoeia⁵ for Yin insufficiency of kidney; dizziness; tinnitus; weakness and soreness of the loins and the limbs; emission and sweating. Many published and unpublished human clinical studies have supported the use of Golden Six Capsules in numerous conditions, some of which are highlighted below.
