Dr Elisabeth Philipps | PhD BSc (Hons) BSc Nutr Med The Cannabis sativa plant yields many different compounds that have been shown to have a wide range of different activities in the body. Many of these compounds are cannabinoids, with CBD (cannabidiol) and THC (tetrahydrocannabinol) being the major forms used for therapeutic benefits for many decades. But as the cannabis plant progresses through its life cycle, other rare cannabinoids can be produced at different stages. Some of these rare cannabinoids, so called because they account for less than 1% of cannabinoids present in cannabis plant biomass, are now coming under research scrutiny for their standalone therapeutic properties.
