Ginseng & Longan Formula (Gui Pi Tang), also known as “Restore the Spleen Decoction,” is a popular formula that is used when excessive or obsessive mental activity injures both the spleen and the heart causing insomnia, palpitations, inability to concentrate, memory loss, anxiety, or phobias. Injury to the spleen impairs its ability to generate and control blood. When the blood is deficient, the heart is not nourished.
This affects the heart’s ability to store the shen (spirit) and the spleen’s ability to store the yi (intelligence).
