    Dong Quai and Anemarrhena is a faithful rendition of the classical formula Tangkuei Decoction to Pry Out Stagnation (Dang Gui Nian Tong Tang), to drain Damp, vent Heat, dispel Wind and disperse constraint. It is indicated for Damp Heat, with a concurrent Wind invasion pattern, with stagnation lodged in the joints and the muscle, that is aggravated by hot, humid weather. Wind and Damp Heat can flow over into the channels, collaterals and joints, obstructing the free flow of Qi and Blood. Damp Heat can flow down to lodge in the legs and can result in Leg Qi, and can cause the Blood to stagnate in the collaterals of the muscle and skin.

    Dong Quai and Anemarrhena also has a supplementing action, which follows the concept that Damp Heat patterns usually appear with an underlying Spleen Qi deficiency, allowing Dampness to settle and accumulate. Li Dong-Yuan, the author of this formula, was the founder of the Spleen/Stomach School of the Jin-Yuan Dynasty. Dr. Li proposed that a weakening of the Qi transformation associated with the Spleen, Stomach and Triple Burner leads to an accumulation of Dampness in the Interior.


    According to Liu Wan-Su’s Theory of Similar Transformation, accumulations in the body eventually transform into Heat, so Damp accumulation will eventually lead to Damp Heat, which Capillaris herb successfully clears. Accumulations of Dampness will also aggravate Blood stasis. Dong quai root is important in this formula for its Blood nourishing and Blood regulating properties.


    Heat clearing herbs include Cimicifuga rhizome and Anemarrhena rhizome, which also drain Fire, and Kudzu root which releases the muscles and nourishes fluids. Wind is dispelled by the inclusion of herbs such as Notopterygium root and rhizome which disperses Cold and unblocks Bi Stagnation, and Siler root, which expels Wind Damp. Chinese licorice root and rhizome tonifies the Spleen, clears Heat and harmonizes the other herbs found in the formula.


    White Asian ginseng root and rhizome and two types of Atractylodes rhizome (Cang zhu and Bai zhu), are included to supplement the Spleen Qi. To address the Dampness resulting from lingering Spleen deficiency, herbs to dry Dampness are included, such as Chinese skullcap root and Shrubby sophora root. To encourage the elimination of Damp, herbs which transform Damp and support healthy urination, such as Asian water plantain rhizome and Polyporus sclerotium, are also key elements.


    If further Spleen Qi support is needed, combine with Shen Ling Spleen Support or Six Gentlemen.
