(Jingyue) This is a formula for treating the deficiency of Kidney Water and the excess of Fire, hence named "Yi Yin Jian" (One Yin Decoction). It is indicated for conditions where the True Yin of the Kidney is damaged, presenting with pulse and symptoms predominantly Yang in nature, such as deficiency-fire fever, and bleeding due to Yin deficiency. It is also suitable for cases following malaria or cold damage where repeated sweating therapies have led to excessive perspiration, resulting in a deficient pulse and weak Qi, yet persistent thirst and irritability, and unremitting tidal fever. These conditions arise from Yin injury due to excessive sweating and the subsequent deficiency of Water; all such cases should be treated with this formula, modified according to the specific presentation.

If Fire is flourishing causing restlessness, add Dang Gui (Angelicae Sinensis Radix) 1-2 qian each to astringe.
(Jingyue) This is a formula for treating Heat in the Heart Meridian and the failure of Water to control Fire, hence named "Er Yin Jian" (Two Yins Decoction).

This is a formula for treating Liver and Spleen deficiency and damage, insufficiency of Essence and Blood, and hemorrhage due to Ying (Nutritive) Blood deficiency, hence named "San Yin Jian" (Three Yins Decoction). It is indicated for conditions such as wind-stroke where Blood fails to nourish the sinews, or after the pathogenic factor of malaria has dispersed but chills and fever persist. These are all diseases of deficiency of Yin and Blood involving the Shaoyang and Jueyin meridians. If there is slight Fire, Yi Yin Jian is appropriate; if there is no Fire, this formula is the primary treatment.

If there is vomiting and nausea, add Wei Jiang (Baked Ginger) 3-5 slices. If there is excessive sweating with irritability, add Wu Wei Zi (Schisandrae Fructus) 14 grains. If there is excessive sweating with Qi deficiency, add Huang Qi (Astragali Radix) 1-2 qian. If there is dull pain in the lower abdomen, add Gou Qi Zi (Lycii Fructus) 1-2 qian.
