oak

(ōk)
A deciduous tree (Quercus spp.) that provides material in its leaves and bark to produce many forms of herbal nostrums. Used as an astringent, a therapeutic remedy for skin disorders (approved for use for this purpose in Germany), and countless other unconfirmed purposes. Because of high levels of tannic acid, it has caused death, respiratory failure, and hepatotoxicity.
