Abstract

The application provides a drying method of Chuanxiong medicinal material and application of Chuanxiong or its extract in preparation of an external medicine for treating atopic dermatitis. The drying method of Chuanxiong medicinal material improves Chuanxiong processing efficiency, shortens processing period, obtains by-product Chuanxiong extract in addition to preparation of decoction pieces, reduces energy consumption and lowers production cost. The Chuanxiong essential oil and Chuanxiong extract are both composed of small molecule components, have good affinity to skin, are absorbed through skin quickly, can quickly relieve symptoms such as itching and skin damage caused by atopic dermatitis, and are natural, safe and free of side effects. Meanwhile, the small molecule components contained in the Chuanxiong essential oil and Chuanxiong extract have good lipophilicity, have softening effect on the thickened stratum corneum caused by atopic dermatitis, and are more conducive to drug absorption. In addition, the Chuanxiong essential oil and Chuanxiong extract are simple to prepare and low in price.
