Adverse effects of cannabinoids on immune function have been observed in experimental animals at doses 50–100 times the psychoactive level (Cabral 2001). In four patients using herbal cannabis therapeutically for over 20 years, no abnormalities were observed in leukocyte, CD4 or CD8 cell counts (Russo et al 2002). Investigation of MS patients on Cannador revealed no major immune changes (Katona et al 2005), and similarly, none occurred with smoked cannabis in a short-term study of HIV patients (Abrams et al 2003). Hematological measures have been normal in all Sativex RCTs without clinical signs of immune dysfunction.
CBD oil is also used by some people who have cancer. A few studies in mice have shown a reduction of cancerous tumors. But most human studies have involved research into the role of CBD oil in managing pain related to cancer and cancer treatment. The National Cancer Institute (NCI) has pointed to CBD as a possible option for relieving symptoms caused by chemotherapy.
Cannabidiol, a non-euphoriant phytocannabinoid common in certain strains, shares neuroprotective effects with THC, inhibits glutamate neurotoxicity, and displays antioxidant activity greater than ascorbic acid (vitamin C) or tocopherol (vitamin E) (Hampson et al 1998). While THC has no activity at vanilloid receptors, CBD, like AEA, is a TRPV1 agonist that inhibits fatty acid amidohydrolase (FAAH), AEA’s hydrolytic enzyme, and also weakly inhibits AEA reuptake (Bisogno et al 2001). These activities reinforce the conception of CBD as an endocannabinoid modulator, the first clinically available (Russo and Guy 2006). CBD additionally affects THC function by inhibiting first pass hepatic metabolism to the possibly more psychoactive 11-hydroxy-THC, prolonging its half-life, and reducing associated intoxication, panic, anxiety and tachycardia (Russo and Guy 2006). Additionally, CBD is able to inhibit tumor necrosis factor-alpha (TNF-α) in its own right in a rodent model of rheumatoid arthritis (Malfait et al 2000). At a time when great concern is accruing in relation to NSAIDs in relation to COX-1 inhibition (gastrointestinal ulcers and bleeding) and COX-2 inhibition (myocardial infarction and cerebrovascular accidents), CBD, like THC, inhibits neither enzyme at pharmacologically relevant doses (Stott et al 2005a). A new explanation of inflammatory and analgesic effects of CBD has recently come to light with the discovery that it is able to promote signaling of the adenosine receptor A2A by inhibiting the adenosine transporter (Carrier et al 2006).
I really like this company. They had all the criteria that I was looking for after hours and hours of research trying to understand the CBD world. I tried the 1,000 strength for joint pain and inflammation. I noticed great relief within a day or two. I tried a full spectrum next, because I had read that the entourage effect would work better. To be honest, it was about the same. But I returned to Medterra because of the purity of their product and the confidence I have in the company. Medterra is doing everything right, from the carrier oil, to the lab results, and the USA non gmo grown plant. :)
Preliminary research indicates that cannabidiol may reduce adverse effects of THC, particularly those causing intoxication and sedation, but only at high doses. Safety studies of cannabidiol showed it is well-tolerated, but may cause tiredness, diarrhea, or changes in appetite as common adverse effects. Epidiolex documentation lists sleepiness, insomnia and poor quality sleep, decreased appetite, diarrhea, and fatigue.
This is good news for the best CBD oil companies because the Farm Bill allows for the legal cultivation of industrial hemp, under certain circumstances, which can be a source of CBD. But CBD can also come from non-industrial hemp, namely the marijuana plant that most are more familiar with. Therefore, whether or not CBD oil for pain is legal can be a question of which “version” of the cannabis plant it was sourced from. If it was sourced from industrial hemp, (which contains less than 0.3% THC by volume), and it was cultivated under the Farm Bill, then it is legal.
Online retailers: Most CBD oils are sold through online retailers. These establishments tend to have the widest product range, and many offer free doorstep delivery. Online retailers also frequently post product reviews, allowing buyers to compare different oils based on customer experiences to determine which is best for them. These reviews can also be used to evaluate the retailer based on customer service, delivery, and product quality.
Hemp Bombs is based in Tampa, Florida, and in addition to focusing on the purity and therapeutic effectiveness of their products, are dedicated to establishing themselves as a top brand in the industry with a specific target audience. One of our personal favorite products of theirs is the flavored CBD vape liquids, which are some of the best-tasting CBD vape juices we’ve ever had.
Hemp oil is also rich in "super" polyunsaturated fatty acids, most notably gamma-linolenic acid and stearidonic acid. Although these are not essential fatty acids, they may help reduce the symptoms of atopic dermatitis and other skin conditions. However, the amount of these non-essential fatty acids varies according to the quality of the hemp plant the acids were derived from.
Cannabis terpenoids also display numerous attributes that may be germane to pain treatment (McPartland and Russo 2001). Myrcene is analgesic, and such activity, in contrast to cannabinoids, is blocked by naloxone (Rao et al 1990), suggesting an opioid-like mechanism. It also blocks inflammation via PGE-2 (Lorenzetti et al 1991). The cannabis sesquiterpenoid β-caryophyllene shows increasing promise in this regard. It is anti-inflammatory comparable to phenylbutazone via PGE-1 (Basile et al 1988), but simultaneously acts as a gastric cytoprotective (Tambe et al 1996). The analgesic attributes of β-caryophyllene are increasingly credible with the discovery that it is a selective CB2 agonist (Gertsch et al 2007), with possibly broad clinical applications. α-Pinene also inhibits PGE-1 (Gil et al 1989), while linalool displays local anesthetic effects (Re et al 2000).
Hemp oil can be found in many different delivery forms. Hemp oil can be consumed orally, applied topically or sublingually, or smoked via vaporization. Vaporization and sublingual application of hemp oil allows for a fast onset-of-action of the CBD, whereas pills and edible products can take 30 to 90 minutes on average to take effect. Topical hemp oil can be applied directly to areas of pain or inflammation, though it can also be absorbed into the systemic circulation.
The extract known as CBD oil sold in the U.S. falls into one of two categories. Crystalline isolate exclusively contains CBD, as other cannabinoids have been removed; full spectrum oil, on the other hand, retains THC and other cannabinoids, and is only sold in states where marijuana use has been legalized. CBD oil can be consumed several different ways, including ingested capsules and food products, vaporizing, tinctures, and topical creams. The soporific effects of CBD oil are linked to its concentration; low-concentration oils will produce minimal effects, while high-concentration oils will produce strong effects.
Our Editor’s Pick is the tincture from CBDistillery. This tincture is available in five strengths ranging from 250mg to 5,000mg, which accommodates a wide range of THC preferences, as well as 15 and 30 milliliter containers. The tincture has a price-point that is slightly below average, making it a good option for value seekers. The tincture, which is non-flavored, routinely undergoes third-party testing to ensure safety and high quality; the testing results are available on CBDistillery’s product pages.
Unless you've been tuned out to the beauty world these last few months, odds are you've heard of an ingredient called CBD (short for cannabidiol). The buzzy ingredient (which, no, won't get you high, even if ingested as an oral tincture or supplement) has now evolved into a bonafide skin-care trend, with brands offering a luxe spin on what used to be a highly niche category. "With an impressive and evergrowing number of studies finding CBD to be a powerful antioxidant and anti-inflammatory among many other properties, it is now being used to treat pain, anxiety, spasms, and much more," New York City-based aesthetician Jeannel Astarita tells Allure. However, when compared to skin-care pillar ingredients like retinols and vitamin C, the research behind CBD's efficacy in skin care (especially beyond the realms of being a temporary topical pain reliever) is still relatively in its infancy. "There is limited data to suggest that CBD may decrease oil production when applied topically," says Joshua Zeichner, director of cosmetic and clinical research at Mount Sinai Hospital, who explains that unlike marijuana, which contains THC (which does have psychoactive side effects), hemp seed oil is a common source of naturally anti-inflammatory cannabinoids — which is what ends up in all of those CBD lotions and potions. "Hemp seed oil also acts as an emollient to smooth rough cells on the skin's surface and offers moisturizing benefits," he adds. So whether you love to slather your skin in serums or treat yourself to a 20-minute mask session, CBD has found its way into virtually every step of our beauty regimens. Here, we present 14 CBD-infused skin-care products to add a hit of calm to your daily routine.
A: We offer two different hemp products. First we have our Virgin Cannabis Sativa Hemp Oil. Our Virgin hemp oil comes from the seeds of the hemp plant. The seeds of the hemp plant contain only trace amounts of cannabinoids. Our Virgin hemp oil is a nutritional oil rich in vegan omegas. Our 3rd party lab test do not show any levels of cannabinoids.

The ECS is responsible for setting the baseline activity levels of our immune system and nervous system, which then work to maintain our health. When the ECS falls out of whack, the systems that are regulated by it can begin to malfunction. CBD promotes the normal health and function of the endocannabinoid system, so it’s possible that CBD can help to alleviate the symptoms of conditions that are caused by dysfunction of the endocannabinoid system.
Taste can be a sign of value, too. Poor quality oils will have a very unpleasant chemical taste, and they can cause significant burning to mouth tissues. A good quality product should be smooth and not cause significant burning. Interestingly, the best quality products are associated with a distinct cannabis taste, indicating that the full spectrum of chemical components (with trace levels of THC) are present.
Yes, there's a new type of topical ointment on the market, and it's infused with the cannabidiol (CBD) from marijuana. Manufacturers claim it can help alleviate acute pain and muscle soreness. CBD is similar to THC, except it's non-psychoactive, meaning some researchers view it as the golden child of medicinal use.

Cohen has found that chronic conditions including autoimmune diseases and pain syndromes can be helped with a 6-mg under-the-tongue tincture (the fastest delivery system) or a 25-mg capsule taken twice a day. Dosages for topical products like lotions are especially hard to determine—there’s no clarity on how much CBD gets into the system through the skin.
As more and more states legalize the use of marijuana, a product known as CBD oil has surged in popularity. A chemical compound found in the cannabis plant, CBD, or cannabidiol, is non-intoxicating and does not cause the noticeable euphoric effects associated with tetrahydrocannabinol (or THC, another marijuana compound). Products marketed as CBD oil may contain THC.
There have been no reports of anyone overdosing on cannabis. One of the unique properties of the chemical components of cannabis, including both hemp and marijuana, is that they don’t cause respiratory or cardiac depression. This sets even recreational use of cannabis widely apart from narcotics and alcohol, both of which can cause severe respiratory depression and death at excessive doses. Excessive doses of hemp, and more especially, marijuana, may make you very agitated and feel terrible, but there are no known deaths from cannabis overdose.
Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
