hemlock

From Middle English hemlok, hemeluc, from Old English hymlīc, hymlīce (“hemlock, bryony,convulvus”, literally “hops-like”), from hymele (“hop-vine”), from Proto-Germanic *humalaz, *humalōn, of unknown origin. Perhaps from Scythian *haumala, a diminutive of *hauma (“ephedra; juice”), from Proto-Indo-Iranian *sauma from Proto-Indo-European *seue- (“to suck; juice”).
