Hemlock Essential Oil
Hemlock Essential Oil is also known as Eastern Hemlock, Hemlock Spruce and Tsuga Essential Oil. As with all essential oils, it's important to doublecheck the botanical name of the oil that you are working with.
I adore the aroma of most conifers, and am particularly drawn to the fresh, crisp, needle aroma of Hemlock Essential Oil.
Aromatically, if you enjoy the aroma of fir and spruce oils, you should be pleased with the aroma of Hemlock Essential Oil. It's especially lovely to work with around Christmas and winter holidays, but its fresh aroma and therapeutic properties makes it wonderful to blend with throughout the year.
As a conifer, it's not surprising that Hemlock Oil is abundant in monoterpenes and also contains about 30-35% esters. Due to its monoterpene content, the oil will be more prone to oxidation. Therapeutically, Hemlock Oil is anti-microbial and is helpful as a decongestant and expectorant.
Emotionally, I personally find Hemlock Essential Oil to be energizing and stimulating when I feel lethargic, but I don't find it to be over stimulating. I find it beneficial to include in diffuser blends intended to help me remain focused, optimistic, calm and balanced.
