What does it do?
In Traditional Chinese Medicine (TCM), Liu Wei Di Huang Wan 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 Liu Wei Di Huang Wan works, some researches have found that Liu Wei Di Huang Wan can increase the number of T lymphocytes and regulate the production of cytokines1, 2 and thus Liu Wei Di Huang Wan may adjust the immune function of our body. Liu Wei Di Huang Wan can also increase the production of sex hormones and of adrenal cortical hormones that have anti-inflammatory function in animal studies3. Moreover, Liu Wei Di Huang Wan 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.

Liu Wei Di Huang Wan 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 Many published and unpublished human clinical studies have supported the use of Liu Wei Di Huang Wan in numerous conditions, some of which are highlighted below.

? Back pain due to the kidney Yin insufficency. Typically, you feel weakness and then soreness of the waist and legs. You may also feel dizziness, faint vision, tinnitus, tiredness, sweat or low fever. You start to forget things and do not sleep well. You feel you are sick but doctors cannot find any underlying cause. You are not alone and these are common problems for people especially professionals who spend hours daily in front of computers and who are getting older (e.g., over 40).

? Sexual performance. You feel you are not as hard as before and do not last as long as before. You feel sore waist the next day and it takes longer time for you to reinvigorate.

? Type II diabetes disease4. In recent years, Chinese doctors have found that Liu Wei Di Huang Wan is very effective in treating diabetes type II disease. In multiple controlled human clinical trials, Liu Wei Di Huang Wan is reported consistently effective in over 90% patients, of which most have their blood sugar levels returned to the normal. The treatment is at least as good as the standard treatment with western medicines. When Liu Wei Di Huang Wan is used together with western medicines, it further enhances the efficacy of the western medicines.

? Menopausal syndrome. In a human clinical trial, 23 women were treated with Liu Wei Di Huang Wan for 3 months, the symptoms of hectic fever, hot flash, sweating, palpitation, and insomnia were significantly improved in 39.1% patients. Additional 60.9% showed some improvement.
