Colla Corii Asini is a blood nourishing, blood replenishing and yin nourishing drug, which also has the effect of tonifying kidney yin, so it is suitable for patients with yin and blood deficiency as well as menstrual dribbling. However, Colla Corii Asini should not be used simply because it is very sticky in nature, and if it is used alone without proper preparation, it may block the flow of Qi. Particular attention should be paid to the fact that some patients, even though they have symptoms of irregular menstruation, also have the pathological mechanism of qi stagnation and blood stasis. At this time, the consumption of Colla Corii Asini should be especially careful, and must be combined with blood activating and qi regulating drugs, otherwise it will aggravate the body’s qi blockage, causing a series of meridian blockage and qi and blood stagnation, and the occurrence of the corresponding diseases.
