True Terpenes Profiles are natural, organic, steam-distilled terpenes from various plant sources from around the world. Terpenes mix well with other plant extracts, concentrates and oils. You can also dilute them with coconut oil, PG, PEG and more (we do not recommend using any PG or PEG in any vaping or edible product). Terpenes will homogenise with agitation which can be sped up by applying low heat. They are not water soluble so they must be diluted with other oils unless you use an emulsifying agent such as sunflower lecithin. For most applications, a 1-3% concentration by volume is adequate but can vary depending on the terpene blend and desired effects.
