Preparation method of granules for treating nephrolith

Abstract

The invention discloses a preparation method of granules for treating nephrolith, which comprises the following steps of: putting climbing fern spore and fried cowherb seed into a cloth bag; then, putting the cloth bag together with lysimachia, polygonum aviculare, baked gizzard pepsin, achyranthes, fringed pink, red sage root, vinegar prepared corydalis tuber and costus root into an extracting tank; adding water for decocting twice; mixing the decoctions; filtering; concentrating the filtered solution to obtain extract for treating nephrolith; mixing sucrose and dextrin in a trough type mixing machine; adding the extract for treating nephrolith; mixing for 15-20 minutes to obtain soft materials; then granulating; drying; and controlling the moisture within 2.0% to obtain the granules fortreating nephrolith. By adopting the invention, the extract yield can be increased by 20% under the condition that the same amount of raw medicines are used, thus the production cost can be greatly lowered; by adopting a double-effect concentrator for concentrating, the production time can be shortened; and moreover, no pollution is caused, the medicinal odor is thick, the cleaning operation is convenient, and the energy sources are saved.

Description

Technical field [0001] The invention relates to a preparation method of a traditional Chinese medicine preparation, in particular to a preparation method of Shenshitong granules for treating kidney stones. Background technique [0002] Kidney stones refer to stones that occur in the renal calyx, renal pelvis, and the junction between the renal pelvis and the ureter. Most are located in the renal pelvis and calyces, and renal parenchymal stones are rare. Plain film shows that there are single or multiple round, oval or blunt triangular dense shadows in the kidney area, with high and uniform density. The edges are smooth, but some are not smooth and mulberry-like. The kidney is the main part of the urinary tract that forms stones. Stones in any other part can originate in the kidney. Almost all ureteral stones come from the kidney, and kidney stones are more likely to directly damage the kidneys than stones in any other part. Therefore, early diagnosis and treatment are very impo...

Problems solved by technology

[0003] The dosage forms of medicines for treating kidney stones are basically tablets or capsules, and its functions are to clear away heat and dampness, promote blood circulation and relieve pain, fossilize and expel stones; but there is no report of granules at present

In the process of preparing tablets or capsules, the yield of the extract is low, generally around 60%. If the yield of the extract is increased, the consumption of raw materials will inevitably be increased, thereby increasing the production cost
