白茅根的本草考证

目的:对白茅根进行全面的本草考证,为白茅根研究提供文献依据。方法:查阅历代本草著作,对白茅根的名称、基原、产地、采收加工与炮制进行考证与整理。结果:白茅根历代有茅根、茹根、白茅等别名;为禾本科植物白茅Imperata cylindrica(Linnaeus)Raeuschel与大白茅Imperata cylindricavar.major(Nees)C.E.Hubbard的干燥根茎;产地逐渐由湖北地区扩大到全国范围均产;历代以粗肥、色白、无须根、味甜者为佳。结论:药典记载白茅根基原为白茅Imperata cylindrica Beauv.var.major(Nees)C.E.Hubb.的干燥根茎欠妥,建议参考《中国植物志》和《Flora of China》对白茅根拉丁学名进行修订,并增加收录大白茅Imperata cylindrica var.major(Nees)C.E.Hubbard.作为白茅根的基原。
