The Candian government’s National Research Council Canada has been granted a patent (10364416) for cannabichromenic acid synthase, a synthase involved in decarboxylating cannabichromenic acid (CBCA) into cannabichromene (CBC) which can act on neurological receptors other than the ones THC and CBD act on. CBC has been implicated in helping grow the human brain by increasing viability of developing brain cells, among other medical applications. The patent teaches how to regulate the CBCA synthase gene for desired CBC content outcomes through genetic engineering, plant breeding, and mutagenesis.
