hemp oil under tongue benefits

While it varies by product, Bhatia says most CBD oil comes in 10 to 15 milligram doses per one milliliter of oil (the size of a standard dropper).

FYI: It is possible for extracted CBD oil to contain trace amounts of THC, since both compounds are present in the plant. So if your workplace has a zero tolerance policy, you might want to steer clear.

Why do people use CBD oil?

“There’s no real control, and there’s no requirement for content or dose in the generally-available dispensaries sold or distributed in the states where it’s legal,” says Welty. He notes that multiple studies have found that over half the time, the dose of CBD on the label is not what’s actually in your bottle. “Ultimately there’s no way to tell how much is in a product,” he says.

Beyond that, there are no other known chronic issues, Welty says. In fact, the World Health Organization has said that “CBD exhibits no effects indicative of any abuse or dependence potential,” and that “CBD is generally well tolerated with a good safety profile.”

The same goes for CBD’s effect on anxiety. At this point, it’s not really clear how or why CBD may help with anxiety, although the drug is well known to have a sedative effect. “It may work on what’s called the endocannabinoid system in your brain,” says Welty. That endocannabinoid system, which impacts the central nervous system, influences neurological activities like pleasure, memory, and concentration.

Long story short: You may as well try holding your CBD oil or tincture under your tongue before swallowing it—you could find that you feel it working slightly faster. Anecdotally, says Dr. Birdsall, experts recommended that you hold it there for at least 60 seconds. (A word of warning: There will be drool.) Your other option is to try a product that’s specifically created to be absorbed sublingually, like Kin Slips, which are kind of like those breath-freshening films that dissolve in your mouth.

After all, if there’s one thing that can be said about the wild west of CBD, it’s that experimentation is key—whether you’re looking for your perfect dose or your perfect delivery method.

Sublingual delivery isn’t always a better option for all substances, points out Dr. Birdsall—some B vitamins, for instance, need to be “activated” by the liver in order to do their jobs—but for certain vitamins and medications, it can be a super effective delivery method.

According to Timothy Birdsall, ND—a member of hemp education platform Prima’s medial advisory group—when you take certain substances sublingually, they can enter directly into your bloodstream, where they’re immediately shuttled to your tissues. Think of it as a shortcut to digestion, which is a longer process in which the substance needs to be ingested, broken down by the stomach, absorbed by the small intestine, and metabolized by the liver. “Not only do many compounds lose potential bioavailability during [the digestion] process, but the time to onset is delayed,” adds chemist Jessie Kater, senior vice president of manufacturing for Curaleaf and Curaleaf Hemp.

Even so, Kater says that “most of the literature supports the notion that CBD has better bioavailability when consumed sublingually versus orally. [and] MCT oil-based tinctures are thought to provide better uptake than a traditional oil.” But, again, there’s no evidence that this applies to the exact CBD oil or tincture that you, specifically, have in your cabinet. As mentioned before, every formulation is different, and those small differences matter when it comes to bioavailabilty.

To find out—because there’s been relatively little rigorous research on CBD to date and I’m a skeptic by nature—I reached out to a doctor and a scientist for the 411. As I suspected, this isn’t a topic that has been studied in depth. Yet there is some reason to believe that certain CBD products may truly be more bioavailable when absorbed under the tongue than if taken through food or drink.

How does this apply to CBD? Surprise, surprise: It’s hard to say. “There has been very little scientific research on the sublingual absorption of CBD,” says Dr. Birdsall. The research that does exist has some inconsistencies, adds Kater, since there are so many factors that affect absorption—such as the quality of the CBD or the pH and consistency of the formulation. Plus, many of these studies focus on formulas that contain both CBD and THC—a psychoactive compound found in cannabis that’s supposed to be absent from CBD-only products—so it’s unclear whether their findings would also apply to a product that contains predominantly CBD.

CBD oil comes as full-spectrum oils or in forms that contain CBD isolates. Unlike isolates, which contain CBD only, full-spectrum oils contain a variety of compounds found naturally in the cannabis plant, including proteins, flavonoids, terpenes, and chlorophyll. Alternative practitioners believe these compounds offer more substantial health benefits, although there is no clear evidence of this.

Part of this response could be explained by the way that CBD acts in the brain. In low doses, CBD may act as an agonist to several receptor sites, meaning it acts similarly to surrounding molecules that normally bind to the receptor, enhancing the signalling of those receptor sites. At higher doses, however, too much activity at the receptor site can lead to an opposite effect, negating the beneficial effects of CBD.

What to Look For

To use CBD oil, place one or more drops under the tongue and hold the dose there for 30 to 60 seconds without swallowing. Capsules and gummies are easier to dose, although they tend to be more costly. CBD sublingual sprays are available as well.

CBD oil can interact with certain medications, including some drugs used to treat epilepsy. CBD inhibits an enzyme called cytochrome P450 (CYP450), which metabolizes certain drugs. By interfering with CYP450, CBD may either increase the toxicity or decrease the effectiveness of these drugs.

Proponents claim that CBD oil can treat a wide variety of health problems, including:

In addition, the stroke volume (the amount of blood remaining in the heart after a heartbeat) was significantly reduced, meaning that the heart was pumping more efficiently.
