Is Liu Wei Di Huang Wan used to nourish kidney yin deficiency or kidney yang deficiency?
The body is experiencing excessive night sweats, and the doctor suggested using Liu Wei Di Huang Wan for regulation. I would like to ask, does Liu Wei Di Huang Wan nourish kidney yin deficiency or kidney yang deficiency?

Six-Ingredient Rehmannia Pill is a traditional Chinese medicine formula used to nourish kidney yin. It is primarily indicated for conditions related to kidney yin deficiency.
This formula consists of six herbs: prepared rehmannia root, cornus fruit, chinese yam rhizome,泽泻, tree peony bark, and poria. It has the function of nourishing yin and reducing internal heat. Kidney yin represents the nourishing and cooling aspect of kidney function. When symptoms of kidney yin deficiency appear, such as soreness and weakness of the lower back and knees, dizziness, tinnitus, tidal fever, night sweats, or frequent nocturnal urination, Six-Ingredient Rehmannia Pill can help regulate these imbalances.
However, if the symptoms are caused by kidney yang deficiency, such as cold intolerance, cold limbs, pale complexion, clear and prolonged urination, or decreased sexual function, Six-Ingredient Rehmannia Pill may not be appropriate. In such cases, formulas that tonify kidney yang, such as Jin Kui Shen Qi Pill, may be more suitable.
