Watermelon cream

When it comes to oral ulcer, people think of watermelon frost, which is used to treat oral disease. But you know how the watermelon frost is made, and we can actually make watermelon frost at home. Remember that when I was a kid, in July and August of the fall, Grandpa made some watermelon frost, and Grandpa's dad was an old Chinese doctor, so he learned medicine from childhood. At that time there would be a cellar in the countryside for food storage, and watermelon cream would be the most suitable. At this point last year, I tried to make my own watermelon frost, but it didn't succeed, and finally I found out why it failed because of the wind, which had to blow the water from the watermelon (i.e. dry) before it turned to frost. So if there's no wind, you can blow it with an electric fan. The watermelon has a long history of use and was first recorded more than 200 years ago. The Qing Dynasty of the Qing Dynasty has been published in the General Encyclopaedia, known by the ancients as “the hysteria of the throat”. The traditional solution is to cut the watermelon, place it in Chinese medicine, place it in a large vat and store it in a cooler ventilator. A few months later, there's a white crystal outside the cask, known as watermelon cream。
