The best frost
As the environment changes, global warming becomes more and more obvious. Now even in winter, it is difficult to see frost in many places. The efficacy of many Chinese medicinal materials in traditional Chinese medicine is also closely related to the environment. For example, we often say that frost mulberry leaves are best after frost. Mulberry leaves are used as medicine, and doctors of all ages believe that it is best after frost. In ancient times, frost mulberry leaves were also known as fairy leaves. Ancient books record that after the frost in October, nine out of the leaves on the mulberry tree had fallen off, and only one leaf remained on the tree, which was called the fairy leaf.
It can be seen that the fairy leaves mentioned by the ancients also specifically refer to frost mulberry leaves, not all mulberry leaves. Frost mulberry leaves can be used directly after being harvested and dried in the sun, or used as medicine or tea, all of which have good effects. Traditional Chinese medicine believes that after the mulberry leaf has been frosted, its taste may be bitter but can turn sweet. Its medicinal effect is cold and cool, and it has good effects such as dispersing wind and heat.
