^ Lydia is extremely intelligent and wolfsbane is a known poisonous plant that contains dangerous alkaloids (the poisonous part) that can effect people as well and werewolves. It grows naturally in windy mountainous regions of North America. Gardeners will sometimes use it to keep undesirable critters out of their garden.

While I agree that the show hasn't stated exactly HOW Lydia knows or WHY she would've retained this information, is it really a stretch to imagine or ACCEPT that she is aware of this plant and its' effects? This just seems to be nitpicking and looking for more to it than we've been shown.
