Rehmanniae, Radix - 4 oz. bulk 熟地黄

Rehmanniae, Radix (steamed) (Chinese: shu di huang) is an important herb to tonify and stabilize the blood and nourish yin. The Ming dynasty's most famous botanist, Li Shi-zhen, wrote that Rehmanniae "generates the Blood-Essence, tonifies the deficiencies of the five Yin organs, penetrates the Blood vessels, benefits the ears and eyes, and blackens the hair." It is the main ingredient in the famous Kidney yin formula Liu Wei Di Huang Wan.

Research in China has shown that it decreases blood pressure and serum cholesterol. Rehmanniae is treated first by steaming and then is pounded flat. When cooked, it swells and returns to its original shape. May be combined with herbs such as Asparagi, Epimedium, and Cuscutae.  Use 9-30 grams in four cups water.
