If you’re an ancient Greek philosopher, then you already know exactly how deadly Hemlock can be. While it can grow up to 12 feet tall and can easily be mistaken for a type of wild carrot, you absolutely do not want to try to eat this monster. Hemlock causes muscular paralysis, which sounds absolutely horrifying, and it’s lethal in very small amounts. As poisoning can result from eating, touching, or even smelling Hemlock, it’s a wonderful scent to put on for days when you want everyone to leave you alone. After all, one sniff by an unsuspecting passerby could prove deadly. That’s a risk we just might be willing to take. Scent Notes: A rich, loamy walk through a pine forest. Oakmoss and coumarin dry down to black musk.
