I boiled it like hell and drank it almost daily for something like 3 months when Jennifer was in Antarctica. I question its toxicity, and suspect that if it’s a problem, it may be when it’s highly concentrated, as in a tincture. I do remember reading about it having some toxic compounds somewhere, and also recall Ray Mears talking about only drinking it in small quantities.
My preparation was to boil the leaves for an hour or so, making a fairly strong tea. Sometimes I would pour that over a black tea bag for a double-strength tea. Sometimes I would drink it straight.
Maybe that explains why I am the way I am? Oops.
Oddly, the scent reminds me of baseball. My dad played in an adult league when I was about 8, and my brother and I would go play hide-and-seek with other kids on the game trails adjacent to the fields. Those trails were packed with it.
