Abstract

The invention discloses dried figwort and a preparation method thereof. The method comprises the steps of figwort digging, cleaning, airing, slicing, microwave vacuum drying, forced air drying and packaging; different drying processes are adopted according to different types of Nanchuan figwort. A microwave vacuum drying technology is applied to the preparation of dried Nanchuan figwort, so that the prepared dried figwort has the advantages of high quality, high efficiency, low consumption and low emission, and the process parameters can be directly used in large-scale production. In the prepared dried figwort, major medicinal compositions of figwort are kept, so that the defects of the conventional medicinal material processing are overcome, and the market benefit can be achieved directly. Moreover, the dried figwort can be taken as high-quality figwort decoction pieces, and is a high-quality medicinal material for development of figwort health-care products.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine processing, in particular to a dried scrophulariaceae and a preparation method thereof. Background technique [0002] Scrophulariaceae is the dried root of Scrophulariaceae Scrophulariaceae, also known as Yuanshen, Black Ginseng, Zhejiang Scrophulariae, Wuyuanshen, etc. It is listed in the 40 commonly used bulk medicinal materials in my country, and has the functions of clearing away heat and detoxification, cooling blood and nourishing yin.
