The invention discloses a suppository for treating haemorrhoids, and belongs to external traditional Chinese medicines for treating haemorrhoids. The suppository is prepared from golden cypress, scutellaria baicalensis, gallnuts and radix sophorae flavescentis by the following steps: 1) adding the golden cypress into ethanol 8 times by weight, carrying out reflux extraction three times, and concentrating the filtrate to obtain golden cypress concentrated liquor; 2) decocting the scutellaria baicalensis for 10 minutes by boiled water 14 times by weight of residual three medicinal materials, adding the gallnuts and the radix sophorae flavescentis and decocting for 2 hours, and filtering; 3) then, adding water 12 times by weight to decoct twice, combining the filtrates obtained by three times, and concentrating to obtain a fluid extract with relative density of 1.10-1.15; 4) adding ethanol into the fluid extract, standing for 18 hours, filtering and concentrating to obtain concentrated extracting liquor; 5) combining the concentrated extracting liquor and the golden cypress concentrated liquor, vacuum-drying and crushing to obtain medical powder; and 6) after uniformly mixing the medical powder with a matrix in a weight ratio of 4:6, carrying out injection moulding and cooling to obtain the suppository. The suppository disclosed by the invention has a good curative effect on hemorrhage, swelling, pains, constipation and the like caused by internal hemorrhoids, external hemorrhoids and mixed hemorrhoids, and is an external medicine for treating haemorrhoids.

The invention discloses a preparation method of high-purity gynostemma pentaphylla total saponin for veterinary drugs. The preparation method is characterized in that a medicinal gynostemma pentaphylla total saponin medicinal material is used as a raw material, and the high-purity target product, namely the gynostemma pentaphylla total saponin for the veterinary drug, is obtained by high-efficiency extraction and separation on the basis of combination of technologies such as continuous countercurrent supersonic wave extraction, ceramic membrane microfiltration and macroporous resin adsorption separation with a conventional solvent reflux extraction principle. The preparation method has the advantages that the product purity and the product yield are improved, the product quality and the high quality are stabilized, the production cost is reduced, the requirements on the development of the high-purity gynostemma pentaphylla total saponin for the veterinary drugs and highly-processed products of gynostemma pentaphylla total saponin are satisfied, the production process is in line with environmental protection requirements, and the difficulty in the coordination of working procedures such as extraction, solvent recovery, enrichment and purification occurring in the volume production process of the gynostemma pentaphylla total saponin for the veterinary drugs is solved through the continuous improvement of the technology and the adjustment of technological processes and technical parameters.

The invention discloses a preparation method of a composition capable of relieving physical fatigue. The method comprises the steps that 1, 1250-2250 parts of American ginseng, 300-500 parts of cordyceps sinensis and 60-100 parts of a grape seed extract are weighed by mass; 2, the American ginseng is taken and heated through an ethanol water solution for reflux extraction, filtering is performed, a filtrate is combined, decompress concentration is performed to obtain thick paste with the relative density being 1.2-1.3 at the temperature of 65-75 DEG C, the thick paste is taken for vacuum drying at the temperature of 65-75 DEG C, and dried materials are smashed into fine American ginseng extract powder; 3, the cordyceps sinensis, the grape seed extract and the fine American ginseng extract powder are mixed to be uniform. The components of the obtained composition have the synergistic effect on relieving physical fatigue, the composition can relieve people which are in the sub-health state and tired for a long time, and the method is simple and free of pollution.
