CBD, or cannabidiol, has become a household name in recent years. But where did it come from? Cannabinoids have been known to mankind for thousands of years. The earliest archeological evidence of human interaction with the cannabis plant was found in China approximately 10,000 years ago. The ancient Chinese were utilizing hemp fiber around 5,000 B.C., and the Chinese pharmacopeia listed cannabis as herbal medicine by 1 A.D.
