This is a well designed formula that addresses Liver Qi constraint when it occurs in the context of a deficiency syndrome, specifically Spleen Qi and Liver Blood deficiency. This condition is marked by failure of the Liver to maintain the smooth and even flow of the Qi throughout the body. The Liver Qi becomes inhibited leading to what is essentially a deficiency type of syndrome. In addition, disruption of the middle Jiao is usually also present. This is because the Liver fails to regulate and promote the normal movements of Qi in the middle Jiao. Because the Qi and the Blood form a complementary pair, Liver Qi constraint is essentially a disharmony between the Liver Qi and the Liver Blood. Thus the later may readily become deficient.
