2. Lowering blood pressure and lowering blood fat: Sweet potato contains a substance called mucin, which can lower the viscosity in the body, smooth blood circulation, dilate capillaries, and slowly lower blood pressure and blood fat, thus achieving the function of protecting blood vessels, effectively preventing arteriosclerosis and diseases, and also preventing sudden changes such as brain flushing caused by the increase of blood pressure and blood fat.
3. Detoxification and detoxification: After drinking wine, a sweet potato can effectively relieve the symptoms such as blushing, headache, brain swelling and stomach discomfort caused by alcoholism, relieve the toxicity of alcohol, and promote intestinal digestion at the same time, so that the alcohol concentration can be quickly discharged from the body after dilution and decomposition, which not only achieves the effect of hangover and detoxification, but also protects the gastric mucosa from the corrosion damage of alcohol.
4. Pesticide preparation: The fruit of sweet potato can be used as food, but its stems, leaves and seeds are absolutely inedible, because its seeds and stems contain a highly toxic substance called rotenone, which is highly toxic to people and animals. Although it can't be eaten, it can also be used to do other things, such as making pesticides to kill insects.
Extended data:
Cold potato likes high temperature, and the temperature required for seed germination is higher than that of general leguminous crops. Plants need sufficient light for vigorous photosynthesis and accumulated assimilation and nourishment, especially during the formation of fleshy roots. Only sufficient light can produce high yield.
The requirement of cold potato for soil is medium fertility and sandy loam. If planted in cohesive soil, the root tuber will be stunted, with rough skin and more fibers. In sandy loam, the root tuber is big and the meat is tender. If the soil is too fertile, it will often cause the vines to grow white, but the fleshy roots will not grow.
Because it is rich in water and carbohydrates, eating sweet potatoes can clean up toxins accumulated in the body, speed up blood circulation and promote metabolism. Moreover, sweet potato itself tastes sweet and juicy, suitable for eating in hot summer, which can not only relieve summer heat, but also clear liver, remove fire and reduce dryness.
Sweet potato is generally regarded as fruit, peeled and washed and eaten raw. Raw sweet potatoes are crisp, sweet and full of water. As a vegetable, it can be said that the sweet potato is shredded and mixed with rice vinegar, sugar, sesame oil and other cold dishes, which is not only sweet and sour and crispy, but also can stimulate appetite, clear heart and quench thirst, and has the functions of promoting appetite and helping digestion.
