For women whose menstrual cycle is usually around 28 days, when the menstrual cycle exceeds 35 days, it is considered as a delayed menstruation. First of all, we should exclude the possibility of pregnancy. Other causes such as stressful work, mental tension and anxiety may lead to delayed menstruation. In Chinese medicine, there are four causes: Qi stagnation, blood stasis, phlegm-dampness and Qi deficiency, which should be regulated separately. If a woman is suffering from liver qi stagnation and emotional discomfort, her menstruation may be delayed due to obstruction of the flow of qi and blood, so relieving emotional discomfort is the first thing to do, and at the same time, you can take the oral Easy Yao Pill; if you also have irritability, hot flashes, chest distension and pain, it is recommended to take Dan Gardenia Easy Yao Pill. If the delayed menstruation is caused by simple blood stasis, Yimoucao cream, which activates blood circulation and resolves stasis, is preferred. Of course, phlegm and dampness may also cause delayed menstruation, women are obese, Chinese medicine believes that “fat people have more phlegm and dampness”, phlegm and dampness block the spleen spleen’s ascending and clearing transportation, spleen spleen deficiency and phlegm and dampness, the two interact with each other, modern medicine polycystic ovary syndrome is this type of evidence, weight loss is necessary, dampness and laxative at the same time with the strengthening of the spleen, and at the same time auxiliary exercise. This is the case with the Ginseng and Atractylodes Pill, which is generally effective for the phlegm-damp type. Women who have been ill for a long time are bound to deplete the spleen and Yang, and the actual evidence becomes deficient, resulting in delayed menstruation due to deficiency of Qi and blood. For this kind of deficiency, it is necessary to follow the clinician’s advice on how to regulate the condition. However, because of the long treatment time and slow efficacy, persistence is needed to achieve the final effect.
