Home » Where Does CBD Come From?

If you’ve been reading the other posts at CBD School, you know that CBD is the non-psychoactive cannabinoid found in both marijuana and hemp plants.

CBD is known to have many benefits:

  • Anti-cancer
  • Anti-epileptic
  • Anti-inflammatory
  • Anti-anxiety
  • Neuroprotective
  • Pain relieving
  • Anti-oxidant

So, where does CBD come from?

CBD and all cannabinoids are produced and concentrated in the resin on the cannabis plant. The beneficial terpenes and flavonoids are also produced and concentrated in the resisn.

When it comes to quality CBD oil, it’s all about the resin.

The resin is a thick substance found in the glandular trichomes in the flower of a cannabis plant. There are smaller amounts of resin also found on the leaves of the cannabis plant. To an even smaller extent, there is some resin found on the stalk and seeds of the cannabis plant.

The resin of a cannabis plant, whether it’s a hemp or marijuana plant, contains the highest concentration of therapeutic compounds – the cannabinoids, terpenes, and flavonoids. This is why we at CBD School recommend you only use CBD oil made from high resin cannabis plants.

The easiest way to know if you are getting a CBD oil from a high resin plant is to look for descriptions like “full plant extract” and “whole plant extract”. A whole plant/full plant extract will ensure that the CBD oil was made using the whole cannabis plant, including the parts where most of the resin is contained: the flowers.
