YES it is true! The patent makes certain detailed claims that we are not permitted to reprint here. According to the US Department of Health and Human Services Patent number 6,630,507, “Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism.….. Nonpsychoactive cannabinoids, such as cannabidoil, are particularly advantageous to use because they avoid toxicity that is encountered with psychoactive cannabinoids at high doses useful in the method of the present invention.”
In fact the US government has filed a series of patents on CBD going all the way back to the 1940’s, and has sparked interest among independent researchers. Hundreds of research papers published since then have been linked back to this US government patent.
