Problems solved by technology

The methods of processing rehmannia glutinosa are recorded in different documents, such as "steaming three or five times", "steaming nine times and making nine times", etc., but most of them are processed according to experience, and the optimal processing method cannot be found yet. Although the requirements can all meet the standard of "light and black as lacquer, sweet as candy", there are differences in medicinal efficacy, which directly affects the curative effect of processed rehmannia glutinosa.
The ancients discovered through clinical practice that only nine times of steaming and nine times of rehmannia can fully remove its coldness and turn it into a warm medicine, and its effect of nourishing kidney and blood can be manifested. Therefore, three or five ti

preparation example Construction

[0046]In the preparation process of processed rehmannia glutinosa, temperature, pressure, and the consumption of yellow rice wine are the three most important conditional factors. A large number of orthogonal experiments of the present invention show that temperature is the most important factor affecting the efficacy and quality of processed rehmannia glutinosa. To obtain The optimal temperature range for nine-steamed and nine-processed Rehmannia glutinosa is 130°C to 150°C, the optimum temperature is 140°C, the pressure is 0.2Mpa to 0.4Mpa, the optimum pressure is 0.3Mpa, and the ratio of raw rehmannia to rice wine is 3:1~ 2:1 is suitable, we choose 2:1 as the optimal ratio. We analyze the optimal preparation conditions. If the temperature is lower than 130°C, the rehmannia glutinosa will not be easily steamed, and the steaming time will be prolonged. In addition, the microbial control is poor. If the temperature is higher than 150°C, the rehmannia glutinosa will be easily st...

[0100] Processed medicine: raw rehmannia decoction pieces

[0101] Yellow rice wine should be old rice wine more than 5 years old, its divergent property is weakened, and its warming and tonic property is strengthened, so steaming Rehmannia glutinosa with aged rice wine is selected to make the warming and tonic effect of Rehmannia glutinosa stronger. If the rice wine is made of old rice wine more than 5 years old, this effect cannot be achieved if the rice wine is selected from the factory. The warming and tonic function of Rehmannia glutinosa is very weak.

[0102] Select 600g of raw rehmannia, implement the "Standard Operating Procedures for Clean Selection Posts", pick out impurities from the raw rehmannia, put them in a clean turnover container, weigh, slice, and the thickness is between 25 and 30mm.
