So, can CBD oil help dogs with allergies?
What’s the science here?
Most allergic responses are inflammatory responses. Many features of allergic inflammation resemble inflammation resulting from immune responses to infection or things like bug bites. As this 2013 paper from Nature writes, allergic disorders ‘trick’ the immune system into reacting to substances that would otherwise be inconsequential to the body.
When the body identifies an allergen, the immune system responds by inducing inflammation, which helps to increase blood flow and send immune compounds to the affected area. As a result, the site becomes hotter, redder, and swollen—which can be anything from mildly irritating to life-threatening, depending on the severity and location of the allergy.
Inflammation is something that CBD has been proven to effectively reduce. By interacting with cannabinoid receptors across the body’s endocannabinoid system, CBD is able to “down-regulate over-reactive immune cells” and enhance the body’s ability to maintain homeostasis in response to external threats and infections.
