以往的扩张末梢血管药物虽有一定疗效,但也有副作用,人们希望能提供安全性很高的药物。本发明提供两种中药制剂: 一种是从黄芪、石斛、丹参和红花的一组中,选择1种或2种以上的中药提取物的有效成分,配伍成改善末梢循环的中药制剂。另一种是从玄参、党参、当归和芍药的一组中,选择1种或2种以上的中药提取物跟上述中药提取物配伍,成为改善末梢循环的中药制剂。通过水、醇类等各种溶媒提取中药的活性成分,根据需要再通过渗析、各种色层分离法等进一步精制含有效成分的该提取物。配伍2种以上中药提取物时,可以分别提取各中药材后,再将其混合。但同时提取2种以上的中药材,而获得的中药混合提取物不仅适用于工业,而且对药效也有利。混合比例可适当选择,一般来说,以等量混合物为宜。
Although the previous drugs for dilating peripheral blood vessels have certain curative effects, they also have side effects. People hope to provide drugs with high safety. The invention provides two kinds of traditional Chinese medicine preparations: One is to select one kind or two or more kinds of active ingredients of traditional Chinese medicine extracts from the group of Radix Astragali, Dendrobium, Salvia miltiorrhiza and Carthamus tinctorius, and to compose a traditional Chinese medicine preparation for improving peripheral circulation. The other is a combination of Scrophulariae, Codonopsis, Chinese angelica, and peony. Selecting one or more herbal extracts is compatible with the above-mentioned Chinese herbal extracts and becomes a Chinese medicine preparation for improving peripheral circulation. The active ingredients of the Chinese medicine are extracted with various solvents such as water and alcohols, and if necessary, the extract containing the active ingredients is further purified by dialysis or various chromatographic methods. When more than two kinds of Chinese herbal extracts are combined, each Chinese herbal medicine can be extracted and then mixed. However, at the same time extracting more than two kinds of Chinese medicinal materials, and the obtained mixed extracts of Chinese herbs are not only suitable for the industry, but also beneficial to the efficacy. The mixing ratio can be appropriately selected. In general, an equal amount of a mixture is suitable.
