Mullein is a common food that can supplement nutrition, but it has no medicinal value and cannot detoxify the bowels. Mullein is an important edible fungus in China, which is widely cultivated and naturally distributed in China. The water content in fungus is high, accounting for 91.8%, and the main nutrients are carbohydrates, accounting for 6%. In terms of vitamins, the carotene content in fungus is high, ranking relatively high among similar foods. In terms of minerals, the magnesium content in fungus is high at 57mg/100g. Moderate consumption of fungus can replenish some of the nutrients needed by the body, but you should not rely solely on the consumption of fungus to maintain the daily activities of the organism, and you should eat a balanced diet. There are no research results showing that fungus has medicinal properties and effects, so it can not be used for detoxification and laxative. If the patient is constipated, you can follow the doctor’s instructions to use polyethylene glycol, Kaiser Permanente, bifidobacteria and other drugs to laxative, usually more intake of fruits and vegetables, grains, drink more water and so on. It is recommended that patients who are not feeling well go to the regular hospital for consultation, and the above medication is in accordance with the doctor’s instructions.
