TCM is a medical science of relationship. the relationship between us and the surrounding is called unity of heaven and man. The relationship between us and viscera should be explained with the five element theory. There are deficiency of kidney Yin, deficiency of kidney Yang, and deficiency of kidney Yin and Yang, which of them have a higher ratio? The deficiency of kidney Yang is higher. Besides the loss of hair, white hair, tinnitus, deafness, and soreness and weakness of waist and knees, people will have frequent micturition. Those who suffer from deficiency of kidney Yang will have frequent micturition, normally, they have water stool, also aversion to wind and cold, clear urine in large amounts. Their urine is very clear without any color, but it is in large amounts. Their body fluid never goes out through sweat and passes the kidney. They seldom sweat, but they urinate frequently. They have a large amount of urine, they are aversion to wind and cold, their tongues are always fat, maybe have many teeth prints. They maybe suffer from deficiency of kidney and spleen. 

As we all know, tonifying kidney is a hot topic, we recommend an ancient proscription to cure the deficiency of kidney Yang, this character represents a kind of herb. Fu Tu Wan, Fu represents FuLing(Poria cocos), Tu represents Tusizi(Cuscuta chinensis Lam.). Tusizi(Cuscuta chinensis Lam.) can tonify both Yin and Yang of kidney, but notifies kidney Yang more. Lianzi(Nelumbo nucifera Gaertn) is relatively peaceful. Since they have clear urine in large amounts, FuLing(Poria cocos) can tonify spleen, Lianzi(Nelumbo nucifera Gaertn) can tonify both spleen and kidney. The dose depends on specific conditions of each person. Those who will easily have excessive heat can’t drink it, they are cordial, those who have red tip of tongue, or with yellow coating, or have pimples on face from time to time, or dry stool, can not drink it. People with great dampness can not drink it too.
