苦地丁为常用中药,具清热解毒,凉血清肿的功能.苦地丁之名收载于《中华人民共和国药典1977年版》,以区别于他种地丁,并规定原植物为罂粟科植物紫堇Corydalis bu-ngeana Turcz.的干燥全草.历来无伪品.1991年5月笔者在安国药材市场上发现一种假 Kudidi is a commonly used traditional Chinese medicine that has the functions of detoxification, cooling and sebum swelling. The name of bitter distillate is contained in “The Pharmacopoeia of the People’s Republic of China, 1977 Edition,” in order to distinguish it from other territories and to provide the original plant as a plant of the family Papaveraceae. The dried whole plant of Corydalis bu-ngeana Turcz. has never been forged. In May 1991, the author discovered a fake on the Anguo medicine market.
