The scent of the cannabis plant comes from the terpenes in the plant. All plants have them, but there are a significant amount in the cannabis plant. Some of the more common terpenes have names like Borneol, B-Caryophyllene, and a-Pinene. So many, too many to list here and we are still learning about the role they each play in the human body. Some are ideal for use as an anti-bacterial, another can be utilized as a bronchodilator. It is also the combination of specific terpenes that are responsible for why you feel either an Indicia high or a Sativa high from one plant to the next. When you hear a particular strain name, it should be indicative of the terpenes in the plant, down to its genetics.
