How to properly handle irregular menstruation?

Patient's question:

Last month
No menstruation

Doctor's answer:

In your case, it may be due to a deficiency of yang and cold closure of menstruation or delayed menstruation caused by cold deficiency. Insufficient nourishment due to blood deficiency, deficiency of Qi and blood in the Chong and Ren meridians, leads to emptiness of the blood sea after menstruation. Combined with Qi deficiency and blood stagnation, there is a lack of power to circulate, which triggers closure of menstruation. It is recommended to use Wenzheng Granules for treatment.
