Though CBD is a new term to you, and a recent addition to the American vocabulary, it is not new to medicine.
Like many other natural remedies, the use of CBD and medical marijuana has been a part of ancient society. The first recorded use of CBDs occurred around 2727 BC in the time of Emperor Sheng Neng of China. He used cannabis-based tea to help with a variety of health issues like poor memory, malaria, and even gout.
CBD has been used in animal experiments for anti-inflammatory properties and to reduce pain by acting on the endocannabinoid and pain-sensing systems. Only a few human trials have examined the efficacy of CBD as a single agent to treat pain, with the majority of researches combining CBD and THC to reduce pain. Notably, Health Canada
has approved a combination of medicine containing both THC and CBD in a 1:1 ratio for the treatments of central nerve-related pain in multiple sclerosis, as well as cancer pain that has not responded to optimal opioid therapy.
