CBN: Cannabinol, or CBN, is a cannabinoid that is created from THC as it ages and degrades. CBN works primarily as a sedative agent, but it has also shown properties of being an anticonvulsant, an anti-inflammatory agent, and having antibiotic properties. As a topical product, CBN may help with conditions such as psoriasis and treating burns. CBN is about a ¼ as potent as its precursor THC, and the degradation of THC into CBN can be sped up by exposing cannabis to light and heat.
CBC: Cannabichromene, or CBC, is a non-intoxicating cannabinoid that acts similarly to the cannabinoid CBD. One of the most abundant cannabinoids, CBC’s effects manifest as strong inflammation reduction and stimulates THC’s analgesic pain-relieving properties. CBC has also shown promising effects on increasing the viability of neural stem cell progenitor cells. This means that CBC can help the cells that create neural stem cells stay alive, which in a cascading effect helps brain function to stay healthy and fight disease.
CBG: Cannabigerol, or CBG, is another non-intoxicating cannabinoid that works to reduce pain, inflammation, and redness in the skin. The receptors that CBG stimulate suggest that CBG may also work to relax muscles and as an anti-depressant agent. Additionally, CBG has moderate anti-fungal effects and is remarkably effective against MRSA (methicillin-resistant Staphylococcus aureus). Promising studies also show that CBG in high doses destroy cancerous cells, most effectively against breast and prostate cancers.
