1, Xueyan is not recommended to eat every day. Long-term use in large quantities may lead to excessive internal heat. Xueyan, similar to peach gum, is the secretion of plant pulp, which has the effects of nourishing yin and clearing away heat, moistening intestine and relaxing bowels, strengthening spleen and tonifying kidney. It is suitable for people with yin deficiency, constipation and qi deficiency, but it cannot be taken every day. Because Xueyan is nourishing, if it is eaten excessively for a long time, it may lead to excessive internal heat, such as dry mouth, aphtha, loss of appetite, bitter taste and bad breath.

Besides, not everyone is suitable for eating snow weir. Xueyan has strong nourishing effect and good laxative effect, which is suitable for constipation patients with spleen deficiency, but not for diarrhea patients with spleen deficiency. Diarrhea will get worse after eating it.

3. Edible snow swallow should be eaten under the guidance of traditional Chinese medicine or nutritionists in regular hospitals, especially pregnant women and children. Don't take it yourself. Because the output of Xueyan is insufficient and the demand is relatively large, there are many fake and shoddy products, and starch mixture may be used for adulteration. Although there will be no adverse reaction after eating, it can't play a role in health care. Therefore, if you want to eat the snow weir, you need to go to a regular pharmacy or manufacturer to buy it.
