Usually, amaranth is not contraindicated for urticaria, but amaranth itself will not have much effect on the recovery of urticaria. Urticaria in Chinese medicine belongs to the category of “addiction rash”, mostly by the internal dampness and heat, external wind and cold, and the skin; clinical manifestations for the skin appeared in varying sizes of air masses, small as a hemp grain, as big as a bean; or even into a block into a slice, itchy, and sometimes hidden. Treatment should be based on elimination of wind, and according to the specific diagnosis, accompanied by elimination of cold, clearing heat, etc.. The Chinese herbal medicine Amaranthus is a heat-clearing medicine, with the function of clearing heat and removing toxins, cooling blood to stop bleeding and stopping dysentery. It is used for symptoms such as heat-poisoned blood dysentery (dysentery caused by feeling heat-poison and seeing blood in the stool), carbuncle and furuncle. For addiction rash does not play a good therapeutic role. Amaranth is cold in nature, so it should not be taken by people with spleen deficiency, loose stools (thin and unformed stools) or diarrhea. The causes and treatments of addiction rashes are complex, and if specific symptoms occur, you should seek medical advice and treatment in a timely manner. Drugs should be used under the guidance of a physician, do not take on your own, so as not to delay the condition.
