Regulating and harmonizing the liver and spleen, relieving pain and spasms.
Cold-damage disease damages yin, leading to the loss of nourishment in the tendons and vessels, resulting in spasms and tightness in the legs and feet, restlessness, and a slight aversion to cold; disharmony between the liver and spleen causes pain in the epigastric region and abdomen.
bubble_chart Formula Principles
This formula is indicated for various syndromes caused by damage to body fluids, deficiency of yin and blood, and loss of nourishment to the sinews. In the formula, Peony Root, which is sour and cold, nourishes the blood and astringes yin, emolliates the liver, and relieves pain; Liquorice Root, which is sweet and warm, tonifies the spleen and replenishes qi, and alleviates urgency and pain. The combination of these two herbs transforms sour and sweet into yin, regulates and harmonizes the liver and spleen, and has the effect of softening the sinews and relieving pain.

When these two herbs are used together, these effects are significantly enhanced.
