A kind of preparation method of medicinal combination of benefiting liver and improving eyesight, nourishing yin and tonifying kidney

Abstract

The invention discloses a preparation method of a combination of medicines for nourishing the liver, improving eyesight and nourishing yin and tonifying the kidney, which relates to a preparation method of the medicine combination. Its formula consists of: 800g medlar, 20g astragalus, 100g Codonopsis radix, 50g Ophiopogon japonicus, 90g donkey-hide gelatin; its preparation method is: 1) remove impurities from the above medicinal materials, and process them into decoction pieces; Rinse it with purified water; 3) Add purified water in stages according to the weight of the above medicinal materials weighed, heat and extract 3 times, filter, and combine to obtain the extract; 4) Melt the donkey-hide gelatin; 5) Continue to concentrate the filtrate to Clear paste with a relative density of 1.20-1.24; 6) Add honey and sodium benzoate, boil to dissolve. It adopts vacuum filtration, which can prevent the loss of active ingredients when removing impurities; it is easy to operate and can effectively control product quality.

Description

Technical field: [0001] The invention relates to a preparation method of a drug combination, in particular to a preparation method of a drug combination for nourishing liver and improving eyesight, nourishing yin and tonifying kidney. Background technique: [0002] There are some deficiencies in the preparation process of the present medlar and astragalus composition: 1. Filtration of the decoction: the original process uses 80 mesh screens to filter, and this filtering method can only filter some larger particle impurities, and still needs to be left to settle The impurity particles that can settle are a waste of man-hours, and the impurity particles that are not easy to settle cannot be filtered out. These impurities are more difficult to remove in the subsequent production process and will remain in the finished product. Concentrate together with the liquid medicine, so donkey-hide gelatin is not easy to dissolve, and the active ingredients will be taken away when removin...

Problems solved by technology

[0002] There are some deficiencies in the preparation process of the present medlar and astragalus composition: 1. Filtration of the decoction: the original process uses 80 mesh screens to filter, and this filtering method can only filter some larger particle impurities, and still needs to be left to settle The impurity particles that can settle are a waste of man-hours, and the impurity particles that are not easy to settle cannot be filtered out. These impurities are more difficult to remove in the subsequent production process and will remain in the finished product. Concentrate together with the liquid medicine, so donkey-hide gelatin is not easy to dissolve, and the active ingredients will be taken away when removing impurities; 3. The original process uses a vacuum concentrator to concentrate the liquid medicine. The temperature of this equipment is uncontrollable during the concentration process, and it is difficult to ensure The stability and consistency of the product will lead to local high-temperature coking; 4. The original process adopts the method of normal temperature sedimentation in the final standing process. Normal temperature is not conducive to the sedimentation of impurities, and it will also affect the stability of the drug
