Humulene, which was first discovered in the hops flower, is the oil that gives beer its pungent odor. This terpene is commonly found in sativa dominant strains, as well as balsam fir trees, basil, cloves, ginger, ginseng, black pepper, oranges, sage, spearmint, sunflowers, and tobacco. Humulene has been used in Chinese medicine for centuries, and physically it is best known as the “cancer killer”. On a cerebral level, humulene soothes overstimulation, and reduces brain activity, which can help reverse states of psychological overload. Some prominent strains are: Arjan’s Haze, Bubba Kush, Girl Scout Cookies,Greenhouse Cheese, Great White Shark, Greenhouse Skunk, Headband, Jack Herer, Kings Kush, Pink Kush, Super Lemon Haze, Sour Diesel, Skywalker OG, The Church, and White Widow.
