Chocolate covered Belladona and Cubeb
I genuinely laughed out loud when I saw this bottle, and knew I had to have it.
Belladona comes from a plant called "Deadly Nightshade", cuz..well, it's deadly. It's been used as both a medicine, and a poison for thousands of years. It's generally regarded as unsafe by modern medicine, on account of it being toxic, and whatnot.
I'm sure Belladona tastes a lot like death, so naturally you'd want to cover it in some chocolate to yummy it up a bit.
