A tropical South American tree with astringent bark, used traditionally in medicine and tanning.
From Tupi or another indigenous Brazilian language, 'barbatimão,' with 'barba' possibly related to beard-like root structures and 'timão' possibly meaning 'useful' or 'medicinal.' The word entered Portuguese and then English through colonial trade.
Indigenous peoples of Brazil discovered that barbatimao bark could stop bleeding and treat wounds—modern chemistry found it works because it's packed with tannins that actually cause tissue to contract and seal wounds, validating thousands of years of folk medicine!
