As previously mentioned, alpha pinene/a-pinene is one of the most commonly found oils within nature. Rosemary, eucalyptus, mint, and dill all have rather large amounts of alpha pinene within them. Evergreen trees are especially known for having high levels of the alpha pinene terpene. In fact, it is for this reason that evergreen trees have such a strong, earthy scent that we commonly refer to as pine, or piney.
