Processing method for prepared rehmannia roots

Abstract

The invention provides a processing method for prepared rehmannia roots. The problem that the medicine effect is affected due to the fact that the prepared rehmannia root processing quality is not stable can be effectively solved. The method comprises the following steps of cleaning, wherein by weight, 100 parts of fresh rehmannia roots with the diameter being 3 cm or larger and 10-30 parts of fresh rehmannia roots with the diameter being 1 cm or smaller are cleaned thoroughly with clean water; drying, wherein the cleaned fresh rehmannia roots with the diameter being 3 cm or larger are placed into a microwave vacuum drying device to be dried; slicing, wherein the dried fresh rehmannia roots are cut into slices with the thickness being 4-6 mm; smashing and juicing, wherein the cleaned fresh rehmannia roots with the diameter being 1 cm or smaller is smashed and juiced, the fresh rehmannia root juice is added into the rehmannia root slices and placed into a steamer to be steamed for 1-2 h; the steamed rehmannia root slices are dried, and the rehmannia roots are ripen. The method is simple and easy to implement, losses of the content of the effective component verbascoside are small, the medicine effect is reserved, the clinic requirement for prepared rehmannia root tablets can be effectively met, and the clinical medicine effect is improved.

Description

technical field [0001] The invention relates to a traditional Chinese medicine, in particular to a method for processing Rehmannia glutinosa. Background technique [0002] Rehmannia glutinosa can be divided into fresh rehmannia, raw rehmannia and cooked rehmannia. Those who use it freshly call it "Fresh Rehmannia", which is cold in nature, sweet and bitter in taste, can clear away heat and promote body fluid, cool blood and stop bleeding. It is used for febrile diseases, crimson tongue, polydipsia, spotting due to warm poison, hematemesis, epistaxis, sore throat; fresh rehmannia glutinosa is slowly baked until it is "shengdihuang", which is cold in nature and sweet in taste, and can clear away heat and cool blood. Nourishing yin and promoting body fluid. It is used for blood entering the camp due to heat, warm toxins and spotting, vomiting blood and epistaxis, febrile disease hurting yin, red tongue and polydipsia, fluid hurting constipation, yin deficiency fever, bone ste...

Problems solved by technology

The Chinese Pharmacopoeia and the processing regulations of various provinces and cities in the past dynasties stipulate that the processing method of Rehmannia glutinosa is to take the medicinal materials of Rehmannia glutinosa and add wine to stew for 48 hours or steam for 24 hours for a long time, and there is also a method of repeated heating, that is, nine steams and nine suns. The rehmannia glutinosa must be cut into thick slices, and the sticky knife is not easy to cut evenly

The current method not only takes a long time to process, but also due to the processing of dried rehmannia glutinosa, the method is backward, the storage time is long, the ingredients are easy to change, and the quality is unstable, which often leads to unstable quality and curative effect of rehmannia glutinosa prepared by it.

In modern times, due to the increase in clinical dosage and the limitation of storage and storage conditions, fresh rehmannia glutinosa is extremely perishable, and dried rehmannia glutinosa is gradually used to process rehmannia glutinosa. Rehmannia glutinosa contains quality standards, but the content of verbascoside, an index component of rehmannia glutinosa, is low and gradually decreases during processing, making it difficult to control the degree of processing, which affects the quality of processing and the effect of use. Therefore, it is imperative to innovate and rationalize the processing method of rehmannia glutinosa
