I've been taking a tincture of Black-Walnut , artemiea absinthium (wormwood), and cloves. Been taking the recommended droppers-full (or so I thought) but on day 9 I awoke with awful vertigo (never had that before)! Stopped taking the stuff then and there, and vertigo is subsiding, but here's my worry: I've read that too much Wormwood can result in vertigo. So, now that I've stopped taking the Wormwood , will the vertigo eventually fade away?
