Professor LIANG Zhiqi differentiates and treats advanced menstruation by focusing on the connections between the

Zangfu

organs and the extraordinary meridians， classifying the condition into excess and deficiency syndromes. The excess syndromes are mostly caused by the invasion of external heat pathogens， which disturb the thoroughfare vessels and conception vessels and force the blood to flow downward prematurely. The deficiency syndromes are further divided into yin deficiency with internal heat disturbing the blood collaterals， and spleen-kidney deficiency with instability of the belt vessels. In response to the different etiologies and pathogeneses of advanced menstruation， Professor LIANG advocates treating both the root and the symptoms， proposing clearing heat to calm thoroughfare vessels， nourishing

yin

and blood， tonifying the spleen and kidney， and strengthening the extraordinary meridians as the main therapeutic principles. For cases of long-standing advanced menstruation or those accompanied by heavy bleeding， different charcoal-processed drugs are selected as needed to achieve hemostasis and delay the menstrual period. In Professor LIANG's approach， "nourishing blood" runs through the treatment of all syndromes， with

Siwu Decoction

as the primary formula. The selective use of various charcoal-processed drugs reflects the principle of treating both the root cause and the symptoms.
