Problems solved by technology

[0003] There are certain deficiencies in the above-mentioned preparation method, such as the main components of rhubarb, a Chinese medicinal material, in hemorrhoid tablets, which are emodin and chrysophanol, and their content is an important index for drug measurement; If the heating time is too long, the content will be reduced, and if the heating time is too short, the extraction will not be complete. The extraction method of rhubarb in the Chinese Pharmacopoeia is: add water to decoct twice, the first time 10 times the amount of water, the second 9 times the amount of water for the second time, due to the large amount of water added and the long heating time, the extraction rate of emodin and chrysophanol in the crude drug rhubarb is usually only about 30%

[0004] In addition, in the preparation method of Pharmacopoeia, Angelica dahurica powder and thick paste are mixed and granulated and dried. Due to the large amount of thick paste, the drying time is long, and the granule properties are unstable, resulting in hard tablets and uneven colors. Clothes Bring Difficulty
