Amaranth can be used to treat skin diseases caused by heat and toxins, such as feverish sores and tansy (an acute infection in which the skin is seen to be red as if it has been coated with paint). Amaranth is a heat-clearing herb with an acidic, cold flavor that goes to the liver and large intestine meridians. It has the effects of clearing heat and removing toxins (removing heat and toxicity from the body), stopping dysentery, and cooling and stopping bleeding (cooling and moistening the blood to prevent bleeding). It is mainly used for treating dysentery caused by heat and poison, with blood in the stools, such as diarrhea and abdominal pain. This medicine can also be used for carbuncle boils (sores on the limbs or face, small in shape with deep roots, as hard as nails), eczema, erysipelas; as well as blood in the stools, hemorrhoidal bleeding, bleeding from leakage (excessive menstruation or dribbling), and so on. For the treatment of feverish sores and ulcers, amaranth can be combined with other heat-removing and detoxifying medicines and decocted, or freshly pounded and applied to the affected area. Amaranth is cold in nature and should be taken with caution by people with cold spleen and stomach (weak and cold spleen and stomach) diarrhea. If you have a skin disease, you should consult a doctor, do not blindly use medicines on your own, so as not to delay the condition.
