Winter is a high incidence season for cardiovascular and cerebrovascular diseases, and its incidence rate is about one times higher than that of summer, while high red blood cell distribution width is one of the important factors that induce cardiovascular and cerebrovascular diseases. Therefore, in order to prevent the occurrence of stroke and heart attack and to relieve the symptoms of cardiovascular diseases, patients are sometimes required to take enteric aspirin for a long time. Medical research has concluded that regular consumption of black cohosh can also effectively relieve the symptoms of high red red blood cell distribution width. In one case, a patient who was diagnosed as having a blocked coronary artery took black fungus for a period of time and then went for a checkup, which showed that the blocked artery segment was cleared. The doctor was surprised and asked the patient how he was treated. The patient replied that he ate black fungus every day. The reason why black fungus is so amazing is that its anti-platelet aggregation effect is comparable to that of enteric aspirin, which is why it is called “food aspirin”. At the same time, black fungus has obvious anticoagulant effect, not only can prevent cholesterol deposition and coagulation on the blood vessels, alleviate the symptoms of high red blood cell distribution width, but also has a good effect on the prevention of atherosclerosis. It should be reminded that when elderly people with weak digestive function consume black fungus, it is best to stew and cook it before eating. If you can make a soup with soaked black fungus and red dates and take a small cup every night, this way of eating is more conducive to the absorption of the body.
