This paper summarizes the clinical experience and medication characteristics of Professor XIAO Chengzong in treating postpartum hypogalactia. It is believed that weakness of the spleen and stomach

depletion of qi and blood

and liver constraint and qi stagnation are the main pathogenesis of postpartum hypogalactia

and "deficiency" and "constraint" are often combined. In clinical practice

spleen

stomach and liver are of major concerns; "supplementing the source of the production

unblocking and draining" is taken as the main treatment principle; Jiawei Gushen Zengru Decoction（加味谷神增乳汤） is recommended as the basic formula and can be modified based on syndrome differentiation.
