CBD

Cannabidiol (CBD) is a non-intoxicating cannabinoid first isolated from cannabis in 1940 by chemist Roger Adams [1]. Unlike its famous cousin THC, CBD doesn't produce euphoria — instead, it acts as a negative allosteric modulator at CB1 receptors, actually dampening THC's psychoactive effects while contributing its own therapeutic properties [2].

While cannabis remains CBD's richest natural source, trace amounts occur in other plants including Echinacea purpurea, where scientists discovered the compound anandamide and began mapping what we now call the endocannabinoid system [3]. Hemp varieties (cannabis with <0.3% THC) have been selectively bred to maximize CBD content, sometimes reaching 15-20% by dry weight.

CBD belongs to the broader class of phytocannabinoids — plant compounds that interact with our body's endocannabinoid system. What makes CBD particularly interesting is its "dirty" pharmacology: unlike pharmaceutical drugs designed to hit single targets, CBD influences multiple receptor systems simultaneously, from serotonin 5-HT1A receptors to vanilloid TRPV1 channels [4].
