I have been making Guyuan ointment for my son. Children have many symptoms such as spleen deficiency and spleen-stomach disharmony due to organ hypoplasia. Children's Guyuan ointment, it is best not to use or use less yellow wine to reduce the symptoms of getting angry. You can use mash instead of yellow rice wine. I always make my own mash. I always steam rice to make fermented grains, and then use fermented grains instead of yellow wine to make solid paste. Children's Guyuan ointment can only use a little donkey-hide gelatin, which is thick and greasy, and the child's spleen and stomach are not perfect. Eating too much Ejiao can easily lead to a child's stomach fire being too heavy, but it is weaker. I have a very detailed introduction in my blog. You can refer to the blog "Follow Me".
