But scientists have found that CBD doesn’t bind well with endocannabinoid receptors. Instead, CBD influences the system indirectly. This creates many benefits, which is why you’ll hear of CBD as a treatment for so many different medical conditions. And, unlike THC, it won’t make you high. When it comes to pain, we know that CBD has multiple functions. First, it influences neurotransmitters and receptors. One receptor known to be involved with pain and inflammation is called TRPV1 — also known as a vanilloid receptor. CBD binds to the TRPV1 receptor, influencing the way you perceive pain. CBD can also affect the production of neurotransmitters like serotonin and glutamate, which are related to pain sensation.
If you haven’t been bombarded with CBD marketing or raves about it from friends, get ready. This extract—which comes from either marijuana or its industrial cousin, hemp—is popping up everywhere. There are CBD capsules, tinctures, and liquids for vaping plus CBD-infused lotions, beauty products, snacks, coffee, and even vaginal suppositories. Already some 1,000 brands of CBD products are available in stores—and online in states that don’t have lenient cannabis laws. This is a tiny fraction of what’s to come: The CBD market is poised to exceed $22 billion by 2022, per the Chicago-based research firm Brightfield Group.
Based in Los Angeles, Calm by Wellness plans to be among the largest hemp-growing and CBD extraction facilities in the world by the end of 2019. The company sources their hemp from Colorado and uses clean CO2 technology to extract their CBD and other cannabinoids (no THC though!). The company is also GMP and ISO9001 food-grade manufacturer certified.
What you gain from Full Spectrum CBD is called the “entourage effect.” Studies have suggested that CBD is most effective when it’s combined with other cannabinoids. Each cannabinoid has its own properties and confers its own benefits. Working together, a synergy is created that boosts the healing properties of CBD. Full spectrum CBD does, however, bring with it the sticky issue of THC. The government regulates concentration levels of THC at 0.3 percent, an amount which results in minimal psychoactivity.
There’s still a lot of unknown territory, but early evidence for CBD’s efficacy is more than enough to justify further large-scale clinical studies — some of which are already in the works. These studies also point to the variety of effective ways to take CBD. This is an important point to keep in mind if you find yourself shopping for CBD products and wondering if the best CBD for pain is a topical, a tincture, or a vape product.
This is the second time Moon Mother Hemp Company has placed among the top five brands on our ranking. The Colorado-based company, which was founded about a year ago, sets the bar very high for quality (including USDA-certified organic hemp) without charging the moon for its products. Their tinctures taste so good, you may be sad you don’t need more.

We’ve linked to the best, most reputable source for each one of these products (most frequently the manufacturer’s site). While you may want to shop around (and we encourage it!), we recommend that you buy from one of our preferred sites. That way you’ll know that you’re getting an authentic product at a reasonable price, from a company that actually stands behind their product.
Another major reason why CBD oil has been positively received in some parts of the medical community is its apparent effect on cancer and tumor growth.A study done by the researchers of the Institute of Toxicology and Pharmacology, University of Rostock, Germany recommends the use of CBD oil (even direct injection into tumors) to eliminate or reduce the size of the tumors. The antioxidants in CBD hemp oil also provide anti-mutagenic properties and lower users’ risk of cancer.
Studies have demonstrated that CBD has a low affinity for the CB1 receptors, but even at low concentrations, CBD decreases G-protein activity (3). CB1 receptors are expressed on many glutamatergic synapses that have been implicated in seizure threshold modulation. CBD may act at CB1 receptors to inhibit glutamate release (4). Studies have shown changes in the expression of CB1 receptors during epileptogenesis and after recurrent seizures (5). CB1 receptor expression is upregulated at GABAergic synapses and shown to be downregulated at glutamatergic synapses in epilepsy, contributing to lowering seizure thresholds.
CBD derived from marijuana is a different story, and the law varies from state to state. But as long as you’re using CBD oil that contains less than 0.3 percent THC, you have nothing to be concerned about anywhere in the United States. On the other hand, if you want to take your CBD on a trip outside the country, definitely look into local laws to avoid getting into awkward situations while you’re away.
Generalized pain, for instance, has dozens upon dozens of high profile research and clinical studies that have been carried out in universities and laboratories around the globe. One of the most well-publicized of these studies took place back in 2008, in which results determined that “cannabinoid analgesics (pain relievers) have generally been well tolerated in clinical trials … with acceptable adverse event profiles (meaning acceptable effectiveness for practical use).
And we have a long way to go before we fully understand the relationship between CBD and pain regulation. But strong anecdotal evidence, combined with multiple lab tests and even some clinical trials, have established that CBD holds a lot of promise for pain relief. Or in science-speak, CBD “represents a novel class of therapeutic agents for the treatment of chronic pain.”
We have receptors for cannabinoids in the whole body, but the first type (CB1) are very dense in the pain pathways of the brain, spine, and nerves. The second type (CB2) are more important for the immune system but is also involved in inflammation. By gently acting on both pathways, our internal cannabinoids and CBD can balance both pain and inflammation .
Pharmacology published a study in 2016 looking at medical marijuana for migraines, specifically in relation to its effects on serotonin, with very positive results. You’ll notice that neither study looked at CBD in isolation from other cannabinoids (which is an issue with a lot of research on CBD and pain). Truthfully, the research on CBD alone just isn’t sufficient to make any pronouncements about its effects on headache pain.
Other targets for CBD include transient receptor potential (TRP) channels that are involved with the modulation of intracellular calcium (1, 6). Cannabinoids are highly lipophilic, allowing access to intracellular sites of action, resulting in increases in calcium in a variety of cell types including hippocampal neurons. CBD actions on calcium homeostasis may provide a basis for CBD neuroprotective properties.
