There are many causes of low menstrual flow. When low menstrual flow occurs, ultrasound and hormone level examination are needed first to rule out organic lesions before symptomatic treatment. According to Chinese medicine, there are two causes of low menstrual flow: deficiency and reality, and for each individual, there is a mixture of deficiency and reality. The main causes are blood stasis and phlegm-dampness, while deficiency is divided into qi deficiency and blood deficiency. “Some women are obese and their spleen deficiency causes water and dampness to stagnate in their bodies and prevent them from producing Qi and blood, and the low menstrual flow naturally recovers through weight loss. Blood stasis is equivalent to river blockage, women with a strong body only need to take drugs to promote blood circulation and eliminate blood stasis when they have their menstruation, and the low menstrual flow can be improved. The low menstrual flow caused by deficiency, or deficiency of endowment, or too many miscarriages, or loss of nourishment during menstruation, postpartum, weakness of the spleen and stomach, insufficient production of Qi and blood, such cases, especially avoid the abuse of the tiger and wolf medicine to promote blood circulation, will make the deficiency on the deficiency, and then cause amenorrhea, infertility, organ prolapse, etc.. The first thing to do is to supplement the qi and blood, you can use moxibustion abdominal acupuncture points, you can also usually take Wuji Baifeng Pills. It is important to note that supplementation must be carried out slowly and gradually, as Chinese medicine has the saying “deficiency is not tonic”, too much supplementation will certainly help the evil fire, sore throat, mouth ulcers, etc. In short, the real evidence of low menstrual flow is to pass and benefit, while the deficiency evidence is to nourish the blood, which must be treated with evidence, not simply activate the blood and remove blood stasis.
