Chinese medicine discusses that blood stasis can be caused by cold, stagnant qi and deficient qi. First of all, blood is warm, but when it is cold, it clots. Women are yin and are weaker by nature than men, so they are more susceptible to cold attacks. For women, it is important to pay attention to prevent cold and keep warm, and eat less cold to avoid more blood clots during menstruation. Of course, usually do moxibustion treatment, moxibustion Shen Que, Qi Hai, Guan Yuan and other acupuncture points, can also achieve the purpose of supporting the Yang. Secondly, women with liver qi stagnation and emotional discomfort also lead to obstruction of the flow of qi and blood, manifested as menstrual blood clots, it is important to maintain a happy mood, and can be combined with the use of Prosperity Pill or Plus Flavor Prosperity Pill.
