CBD is the major non-euphorigenic component of Cannabis sativa. Some research is beginning to show that CBD is different than other well-studied cannabinoids. All cannabinoids function as ligands, meaning they dock onto the binding site of a protein and have the ability to modulate a receptor’s behavior. CB1 receptors are widely distributed, but are particularly abundant in areas of the brain, including those concerned with movement, coordination, sensory perception, emotion, memory, cognition, autonomic and endocrine functions.
The NCBI study does mention some potential side effects for cannabidiol, such as the inhibition of hepatic drug metabolism and decreased activity of p-glycoprotein. CBD can indeed interact with a series of pharmaceuticals, as it inhibits the activity of some liver enzymes called cytochrome P450. This family of enzymes metabolizes most of the pharmaceutical drugs used to treat humans.
Oils are hot in the beauty world. As a beauty editor, I’ve slathered everything short of butter onto my face: argan, coconut, rosehip, sandalwood, chia, neroli, calendula, mandarin, macadamia, rice bran, seabuckthorn, patchouli, grapefruit seed, sesame seed, soybean, sweet almond, pomegranate seed, lemon myrtle, sunflower seed—even extra virgin olive oil from my pantry when I was desperate. I’ve washed my face with oil-based cleansers, and dabbed expensive mixtures being sold as “face oils” onto my skin in hopes of achieving that Instagram-ready glow. Contrary to popular belief, the right oil is actually good for your face and won’t clog your pores. Your skin needs a reasonable amount of oil to do its business; as a matter of fact, if you scrub away all your natural face oil (as I was prone to do with rubbing alcohol as a frustrated and misguided pizza-faced teen), you may actually be prone to more breakouts as your skin tries to make up for the imbalance. As cannabis meets up with the mainstream beauty world, cannabidiol (CBD) oil may be the next big thing.
Putting this in perspective, eating a portion of grapefruit would have a similar effect on the aforementioned liver enzymes. So neutralizing P450 enzymes should be viewed as a minor side effect of cannabidiol. However, if you are taking pharmaceutical drugs and wish to take CBD, you should discuss any potential complications regarding reduced P450 enzyme activity with your doctor and/or pharmacist.
