CBD and Animals

CBD et Animaux

CBD as a treatment for humans or in veterinary medicine is the subject of increasing numbers of studies.

Positive effects seem to be confirmed over time on various symptoms, diseases and behavioral disorders.

CBD binds to different receptors, particularly those of the endocanabinoid system.

The mechanisms of action have been demonstrated in the central and peripheral nervous system (1,2).

CBD also acts on CB2 receptors, mainly expressed on cells of the immune system.

The multiple locations of these receptors explain the relatively broad spectrum in terms of therapeutic potential to be explored.

Regarding veterinary medicine, publications are increasing (4).

Studies highlight a possible anxiolytic effect with an improvement in stress management (2,5,9) and pain (10).

Studies on possible toxicity of CBD have also been carried out, with very reassuring and favorable results, even at high doses (6).

Note that THC is toxic in animals, due to a particularly high number of CB1 receptors.

The benefit of CBD against canine epilepsy in one study demonstrates a significant reduction in the frequency of seizures (7,8).

Use to combat osteoarthritis and associated pain does not show any notable side effects (10).

In cancerous animals, a study showed the benefit of combining CBD with radiotherapy with a view to increasing survival time and improving quality of life (11).

Research on the effects of CBD, both in humans and animals, must obviously continue, to be able to consolidate the results on the hoped-for benefits.

The scope of action seems quite substantial and will perhaps improve well-being and the therapeutic arsenal available.
