Many Chinese “herbs” are actually animal products. The Chinese as a rule are not disposed to vegetarianism, and medicinals derived from animals are thought to be extremely potent, as they are closer to us that plants. E Jiao is one such “herb”. It is basically donkey-hide gelatin, and is used for deficiency patterns such as dizziness, weakness, and any kind of bleeding disorders such as nosebleed, blood in urine, and irregular menstruation.
