Summary
[edit]DescriptionPhellodendron amurense,キハダ,黄檗(オウバク)P5026690丹波市立薬草薬樹公園.JPG |
English: Phellodendron amurense,キハダ,黄檗(オウバク)
日本語:Phellodendron amurense,キハダ,黄檗(オウバク)丹波市立薬草薬樹公園 キハダ(黄檗、黄膚、黄柏。学名 Phellodendron amurense)はミカン科キハダ属の落葉高木。アジア東北部の山地に自生しており、日本全土でもみることができる。 樹皮の薬用名は黄檗(オウバク)であり、樹皮をコルク質から剥ぎ取り、コルク質・外樹皮を取り除いて乾燥させると生薬の黄柏となる。黄柏にはベルベリンを始めとする薬用成分が含まれ、強い抗菌作用を持つといわれる。主に健胃整腸剤として用いられ、陀羅尼助、百草などの薬に配合されている。また強い苦味のため、眠気覚ましとしても用いられたといわれている、また黄連解毒湯、加味解毒湯などの漢方方剤に含まれる。日本薬局方においては、本種と同属植物を黄柏の基原植物としている。 |
