金印草（学名：Hydrastis canadensis），又名白毛茛或北美黄莲，是多年生的毛茛科植物，原产于加拿大东南部及美国东北部。它们的根茎粗壮及呈黄色。在地上的茎略带紫色及有毛，地底下的呈黄色，连接着根茎。金印草的叶子呈手掌状及有毛，叶子上有5-7块双锯齿的小叶，并会在春末长出单支细小的花朵。在夏天会长出单一个草莓，外观像山莓，有10-30颗种子。

金印草有多种医药疗效，包括可以作为抗菌药、内服帮助消化、或是用来漱口清除口腔溃疡。

日本的白根葵以往被分类在金印草属中，现已改为分类在白根葵属。

植株

Goldenseal (Hydrastis canadensis), also called orangeroot or yellow puccoon, is a perennial herb in the buttercup family Ranunculaceae, native to southeastern Canada and the eastern United States. It may be distinguished by its thick, yellow knotted rootstock. The stem is purplish and hairy above ground and yellow below ground where it connects to the yellow rhizome. The plant bears two palmate, hairy leaves with 5–7 double-toothed lobes and single, small, inconspicuous flowers with greenish white stamens in the late spring. It bears a single berry like a large raspberry with 10–30 seeds in the summer.
