Cannabis is the future of human and animal medicine.
The understanding of the medical benefits of cannabis in humans is growing rapidly. Acceptance of the plant as a health product and availability of testing is also growing.
It’s vitally important that cannabis use in both humans and animals is taken very seriously. Cannabis, especially the cannabinoid CBD has the potential to become an alternative to a multitude of pharmaceutical medications. Offering few, if any, side affects, cannabis can help horses to live a healthier, more natural life.

What is the Endocannabinoid System?
Cannabis has been at the center of one of the most exciting—and underreported—developments in modern science. Research on marijuana’s effects led directly to the discovery of a previously unknown biochemical communication system in the human body, the Endocannabinoid System, which plays a crucial role in regulating our physiology, mood, and everyday experience.
The discovery of receptors in the brain that respond pharmacologically to cannabis—and the subsequent identification of endogenous cannabinoid compounds in our own bodies that bind to these receptors—has significantly advanced our understanding of human biology, health, and disease.
It is an established scientific fact that cannabinoids and other components of cannabis can modulate many physiological systems in the human brain and body. Cannabinoids are chemical compounds that trigger cannabinoid (and other) receptors. In addition to cannabinoids produced by the plant, there are endogenous cannabinoids (such as anandamide and 2AG) that occur naturally in the mammalian brain and body, as well as synthetic cannabinoids created by pharmaceutical researchers.
Extensive preclinical research—much of it sponsored by the U.S. government—indicates that CBD has potent anti-tumoral, antioxidant, anti-spasmodic, anti-psychotic, anti-convulsive, and neuroprotective properties. CBD directly activates serotonin receptors, causing an anti-anxiety effect, as well.
What is CBD?
Cannabidiol (CBD) is a naturally occurring compound found in the resinous flower of cannabis, a plant with a rich history as a medicine going back thousands of years. Today the therapeutic properties ofCBD are being tested and confirmed by scientists and doctors around the world. A safe, non-addictive substance, CBD is one of more than a hundred “phytocannabinoids,” which are unique to cannabis and endow the plant with its robust therapeutic profile.
CBD is closely related to another important medicinally active phytocannabinoid: tetrahydrocannabinol (THC), the compound that causes the high that cannabis is famous for. These are the two components of cannabis that have been most studied by scientists.
Both CBD and THC have significant therapeutic attributes. But unlike THC, CBD does not make an animal feel “stoned” or intoxicated. That’s because CBD and THC act in different ways on different receptors in the brain and body.
How Does CBD Work?
Cannabidiol (CBD), a non-intoxicating component of the cannabis plant, has generated significant interest among scientists and physicians in recent years—but how CBD exerts its therapeutic impact on a molecular level is still being sorted out. Cannabidiol is a pleiotropic drug in that it produces many effects through multiple molecular pathways.
Here are some of the ways that CBD confers its manifold therapeutic effects.
ANXIETY - MOOD - PAIN
Jose Alexandre Crippa and his colleagues at the University of San Paulo in Brazil and King’s College in London have conducted pioneering research into CBD and the neural correlates of anxiety. At high concentrations, CBD directly activates the 5-HT1A (hydroxytryptamine) serotonin receptor, thereby conferring an anti-anxiety effect. This G-coupled protein receptor is implicated in a range of biological and neurological processes, including (but not limited to) anxiety, addiction, appetite, sleep, pain perception, nausea and vomiting.
CBD directly interacts with various ion channels to confer a therapeutic effect. CBD, for example, binds to TRPV1 receptors, which also function as ion channels. TRPV1 is known to mediate pain perception, inflammation and body temperature.
CBD binds to TRPV1, which can influence pain perception.
BONE DENSITY - BLOOD PRESSURE - CANCER
Cannabidiol directly activates the 5-HT1A serotonin receptor and several TRPV ion channels, some studies indicate that CBD functions as an antagonist that blocks, or deactivates, another G protein-coupled receptor known as GPR55.
GPR55 has been dubbed an “orphan receptor” because scientists are still not sure if it belongs to a larger family of receptors. GPR55 is widely expressed in the brain, especially in the cerebellum. It is involved in modulating blood pressure and bone density, among other physiological processes.
GPR55 promotes osteoclast cell function, which facilitates bone reabsorption. Overactive GPR55 receptor signaling is associated with osteoporosis. CBD may act to decrease both bone reabsorption and cancer cell proliferation.
PPARS - NUCLEAR RECEPTORS
CBD also exerts an anti-cancer effect by activating PPARs [peroxisome proliferator activated receptors] that are situated on the surface of the cell’s nucleus. Activation of the receptor known as PPAR-gamma has an anti-proliferative effect as well as an ability to induce tumor regression in human lung cancer cell lines.
CBD AS A REUPTAKE INHIBITOR
INFLAMMATION - ANXIETY
CBD’s anti-inflammatory and anti-anxiety effects are in part attributable to its inhibition of adenosine reuptake. By delaying the reuptake of this neurotransmitter, CBD boosts adenosine levels in the brain, which regulates adenosine receptor activity. A1A and A2A adenosine receptors play significant roles in cardiovascular function, regulating myocardial oxygen consumption and coronary blood flow. These receptors have broad anti-inflammatory effects throughout the body.
