Wheat grass is the tender stem and leaf of Gramineae wheat, which is called "wheat seedling" in Chinese medicine. It is recorded in ancient Chinese medicine books that wheat seedlings can "eliminate alcoholism, sudden fever, alcohol jaundice and malnutrition", and have excellent effects of diminishing inflammation and reducing fever, invigorating stomach and promoting digestion, and dredging gastrointestinal tract. Modern medicine has proved that wheat seedlings are rich in chlorophyll, vitamins A, C, E and B, minerals such as calcium, magnesium, phosphorus, iron and selenium, super antioxidant SOD, fiber and beneficial enzymes. In addition, drinking wheat straw juice can also reduce blood pressure, blood lipid and cholesterol, and reduce the incidence of cardiovascular diseases. Patients with hypertension and hyperlipidemia can eat it. Wheat grass is rich in cellulose, which can reduce constipation after taking it. Colitis, gastrointestinal fever, hyperactive liver, and mild abnormal liver function indexes can be drunk frequently. Among them, super antioxidant SOD can help eliminate free radicals in the body and reduce the probability of cell damage or mutation. Because the fiber of wheat straw is very tough, freshly squeezed wheat straw juice is usually provided by a special juice shop, so it is difficult to extract it from a home juicer. Wheat grass can be harvested and juiced after seven days of germination. Wheat straw juice is cold because of its short development time, that is, people with cold hands and feet, weak stomach and diarrhea should not eat more. Otherwise, eating too cold food can easily stimulate sensitive gastrointestinal tract and cause vomiting or diarrhea. In addition, when eating, you should choose a variety of vegetables to eat together (such as tomatoes, celery, cauliflower, bitter gourd, cabbage, spinach and so on). ), so that you can not only absorb a variety of nutrients, but also reduce the coldness of wheat grass.
