Onion is a common condiment and a traditional Chinese medicine. This legend was discovered by Shennong when he tasted a hundred herbs. Although it may not be reliable, it was officially used as medicine in Shennong Materia Medica in the Han Dynasty.
The medicinal part of onion refers to the bulb near the root, which is called scallion. Its taste is pungent and warm, and it has the effects of sweating, relieving exterior syndrome, dispelling cold and activating yang. Modern pharmacological research shows that scallion has the function of sweating and antipyretic. Can strengthen the stomach, diuretic and expectorant. Among them, allicin contained in green onions has a certain inhibitory effect on Shigella dysenteriae, Staphylococcus and dermatophytes.
In winter, due to the cold, it is easy to catch a cold and have a stuffy nose. Take 30 grams of scallion, decoct it in water twice, and take it warm. After taking it, eat 1 bowl of hot porridge, cover with a quilt and sweat slightly, and the symptoms will be relieved. At the same time, it can also be decocted with ginger and brown sugar to make a "ginger sugar and scallion drink" with better effect. In ancient times, there was "onion and black bean soup", that is, onion and black bean soup, which was effective for colds with mild illness. Folk also use onion root, cabbage root and radish root to make soup, which is called "three root soup" and is taken in winter to prevent colds.
In addition, for cough caused by cold, try onions: use onions 15g, pears 1g, 30g of sugar, decoct in water, eat onions, pears and drink soup. Even when you have a bad appetite and can't eat well, adding some onions to vegetables and frying them together, or simply drinking 10 gram of scallion with water, all have the effect of invigorating the stomach.
Scallion can also be used externally. Use 1 scallion and 1 single purple garlic, peel, wash, mash and apply to corns. Generally, the corns will turn black after 4 ~ 5 days, and then fall off every 1 ~ 2 days (this prescription is effective for mild corns). You can also mash scallion, add the same amount of honey, mix well and apply externally to treat suppurative infection. For the treatment of urinary tract obstruction, chopped scallion can be added with the same amount of salt, then wrapped in cloth, and the navel and lower abdomen can be scalded once, once a day 1 time. Or mash 500 grams of green onions, add 0.9 grams of musk and mix well, and scald the abdomen repeatedly, all of which have certain effects.
