Eczema is a very common disease in dermatology, and amaranth is also a commonly used herbal medicine with the effect of clearing heat and dampness. Amaranthus is used in the treatment of eczema, mainly in the acute stage of eczema, where the clinical manifestations are more pronounced oozing and accompanied by intense itching. In this case, it can be combined with other herbs, such as bitter ginseng, raw rhubarb, and cypress, etc. After decocting, it is recommended to apply cold and wet compresses to the affected area to mention the anti-inflammatory and astringent effects of these exudations, which is still quite effective. For eczema, especially the damp-heat type of eczema, it is also possible to treat eczema with Amaranthus with other medicines, such as gentian diarrhea of the liver soup, which can be taken internally with a reduction.
