Skin allergy is called “wind rash” in Chinese medicine. The capsule can be used to relieve itchy skin caused by blood deficiency and wind dryness, and is effective for some allergic people. The capsule contains He Shou Wu, Mulberry Leaf, Radix et Rhizoma Dioscoreae and other herbs, which can nourish blood and nourish yin, dispel wind and relieve itching (by removing the wind that invades the surface of the skin to relieve itching), and moisten the bowels and pass stools, and can be used to treat the discomforts of blood deficiency and wind-dryness, such as itchy skin, hemorrhoids and constipation. Although the capsule can relieve itching caused by blood deficiency and wind dryness, it is effective for some people with allergies. But not all allergies can be used to treat patients, if the condition is more serious, but also need to combine the physical condition, under the guidance of the doctor to use antihistamines, such as loratadine, cetirizine and so on.
