cb1 & cb1 receptors

How can one herb help so many different conditions? How can it provide both palliative and curative actions? How can it be so safe while offering such powerful effects? The search to answer these questions has led scientists to the discovery of a previously unknown physiologic system, a central component of the health and healing of every human and almost every animal: The endogenous cannabinoid system, also known as the endocannabinoid system or ECS.

The ECS has three basic components: endocannabinoids, cannabinoid receptors, and hydrolytic enzymes that break down endocannabinoids. Endocannabinoids are molecules produced by cells that have activity similar to THC and the other phytocannabinoids (plant-derived cannabinoids). They are synthesized on the cell membrane from omega-6 fatty acid precursors. Both endo- and phytocannabinoids act on cannabinoid receptors, known as CB1 and CB2, found throughout the body. Stimulating the CB receptors leads to a variety of physiologic processes inside the cell. Finally, enzymes responsible for the breakdown and recycling of endocannabinoids, MAGL and FAAH, modulate the activity of the ECS.

Sea squirts, newts, rodents, and all vertebrate species share the endocannabinoid system as an essential part of life and adaptation to environmental changes. By comparing the genetics of cannabinoid receptors in different species, scientists estimate that the endocannabinoid system evolved in primitive animals over 600 million years ago, long before the cannabis plant evolved 34 million years ago.

The ECS is perhaps the most important physiologic system involved in establishing and maintaining human health.

Endocannabinoids and their receptors are found throughout the body: in the brain, organs, connective tissues, glands, and immune cells. In each tissue, the cannabinoid system performs different tasks, but the goal is always the same: homeostasis, the maintenance of a stable internal environment despite fluctuations in the external environment. Cannabinoids promote homeostasis at every level of biological life, from the sub-cellular, to the organism, and perhaps to the community and beyond.

Endocannabinoids are found at the intersection of the body’s various systems, allowing communication and coordination between different cell types. At the site of an injury, for example, cannabinoids can be found decreasing the release of activators and sensitizers from the injured tissue, stabilizing the nerve cell to prevent excessive firing, and calming nearby immune cells to prevent release of pro-inflammatory substances. Three different mechanisms of action on three different cell types for a single purpose: minimize the pain and damage caused by the injury.

The endocannabinoid system, with its complex actions in our immune system, nervous system, and all of the body’s organs, is literally a bridge between body and mind. By understanding this system we begin to see a mechanism that explains how states of consciousness can promote health or disease.

In addition to regulating our internal and cellular homeostasis, cannabinoids can influence a person’s relationship with the external environment. Socially, the administration of cannabinoids (especially THC) can alter human behavior, often promoting sharing, humor, and creativity. By mediating neurogenesis (the growth of new brain cells), neuronal plasticity (forming new connections between brain cells), and learning, cannabinoids may directly influence a person’s open-mindedness and ability to move beyond limiting patterns of thought and behavior from past situations. Reformatting these old patterns is an essential part of health in our quickly changing environment.
