Tsuga Essential Oil
The Canadian Hemlock Tree produces a therapeutic grade essential oil that has been used by the North American Indian tribes for hundreds of years commonly referred to as Tsuga Essential Oil. They made a tea from the twigs.
By the way, there is some confusion over the Canadian Hemlock Tree and Tsuga essential oil. This is NOT the poison hemlock which is Conium maculatum.
The famous hemlock poison you hear about is from the Conium species, not Tsuga; so make sure you educate your friends! You don’t want to miss out on such wonderful oil!
