Scientists have made a lot of progress in understanding how CBD produces its calming, pain-reducing, anti-inflammatory effects in the body—and there’s still more to learn. We know that CBD interacts with many different receptors, proteins, and other chemicals in the brain. These interactions create changes in the activity of neurotransmitters, hormones, and other cells throughout the brain and body. Through these interactions, CBD appears to be able to affect many of the body’s functions, from sleep-wake cycles and emotional regulation to inflammation, pain perception, and seizures.
People suffering from other neurological disorders might also benefit from using CBD oil as part of their treatment. Several studies involving Parkinson’s disease showed that participants slept better after treatment. Furthermore, their overall quality of life increased. Amazingly, CBD also showed positive benefits in treating or preventing Alzheimer’s disease. As CBD lowers inflammation, it helps prevent nerves from degenerating. During one study, scientists used mice with the genetic predisposition for Alzheimer’s disease. They found that CBD helped by preventing the mice’s cognitive decline.
But it’s not just that coffee shops don’t have to be specific about what CBD in a latte is supposed to do, and thus don’t — legally, they can’t. “Once anyone, outside of the one FDA-approved medication, says ‘Hey, if you drink this, it’ll cure your anxiety, or your seizures, the FDA is going to come knocking at that point,’” says Carson. When shops offer CBD-infused products, then, they are relying on the customer — and perhaps the placebo effect — to fill in the blanks.
Then there’s the issue of vomiting and nausea after chemotherapy. Most people that underwent chemo know that there is proper medication for these side effects. However, these meds often don’t achieve the desired effect. It’s no wonder that people are looking for alternatives like CBD. During one study, 16 participants that had chemo treatment used a CBD-THC combination. This combo was administered through a spray. Nearly all participants agreed that this helped lower vomiting and nausea.
