ISA HERRERA HEARD IT from her patients first. "I have less pain." "I'm having less anxiety." "My menstrual cramps are less intense," they told the New York City physical therapist about taking CBD oil, a product containing cannabidiol, one of many chemicals found in the cannabis plant. "I was like, 'I need to find out more about this,'" recalls Herrera, who specializes in integrative pelvic floor therapies.
Isolates are typically the CBD oil product of choice for those who get drug tested or are sensitive to other cannabinoids such as THC. Products labeled as isolates will generally be highlighted as being 99+% “pure CBD.” Usually, these products will have nothing but CBD in them because the CBD has literally been isolated from everything else. You can find pre-made isolate oils that typically consist of a carrier oil, such as MCT oil, infused with the crystalline isolate powder. You can also find the “raw” CBD crystalline powder or slabs (a form of concentrate) on its own.
Extracts of CBD—either from marijuana or hemp (a cannabis variant that is essentially free of THC)—are sold as an oil or in tinctures. You can also get CBD via a transdermal patch, capsule, sublingual spray, gel, cream, or vapor. Some contain pure CBD extract (or so they say); others—particularly if you’re in a state where recreational marijuana is not legal—will contain hemp extract, which includes CBD as part of its makeup. As of this reporting, recreational marijuana is legal in nine U.S. states and medical marijuana in 29. Don’t miss these 50 weird things that are banned in the United States.

Cutting-edge science has shown that the endocannabinoid system is dysregulated in nearly all pathological conditions. Thus, it stands to reason that “modulating endocannabinoid system activity may have therapeutic potential in almost all diseases affecting humans,” as Pal Pacher and George Kunos, scientists with the U.S. National Institutes of Health (NIH), suggested in a 2014 publication.
You can also mix this full-spectrum hemp CBD oil into your favorite beverage. Keep the Bluebird Botanicals CBD oil refrigerated, and shake well before use. While most people find their sweet spot at around 15 drops, your serving size may vary according to your metabolism. Since there are no side-effects and there is no danger of overdosing, you can safely tweak your serving size to find the perfect amount of CBD your body needs. Below you’ll find CBD concentration conversions according to Bluebird Botanicals:
CBD has become quite popular over the last couple of years but despite what you might think, it is only one of the 100+ compounds that have been identified in the Cannabis Sativa L plant. Full Spectrum CBD oil, unlike CBD isolate products, includes a wide range of cannabinoids present in the cannabis or hemp plant. Depending on the condition and what you are looking to achieve, it can provide a greater effect than CBD alone as all the cannabinoids work together in what is known as the entourage effect (more on that later).

“There’s no oversight,” says Marcel Bonn-Miller, PhD, adjunct assistant professor of Psychology in Psychiatry at the University of Pennsylvania and author of the JAMA article. Beyond the label, he adds, “There’s no consistency. You know that every Hershey’s bar you buy and every Coke you buy will be exactly the same. But that’s not the case with the majority of CBD products. It’s not unexpected to see variability within a given brand.” This means that you may notice improvements the first time you buy and try a particular product, but none the next.


Full spectrum CBD includes hundreds of active compounds, each in varying amounts and potencies, each with their own subtle action. The Entourage Effect predicts that some of these compounds can work in concert with each other to produce larger effects than they could individually, and that some compounds support the actions of others or even help render active compounds that normally wouldn’t be.
If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.

Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.

Full spectrum CBD also contains a variety of essential vitamins, minerals, fatty acids, protein, chlorophyll, terpenes, flavonoids, and fiber. When referring to CBD in the hemp plant, it’s important to understand that hemp contains a large number of cannabinoids (in trace amounts), but the main compound is cannabidiolic acid (CBDa). As CBDa is more abundant in the hemp plant, firms must decarboxylate the oil. This process heats the oil and changes CBDa into CBD.

For applications where pure CBD isn’t required, full spectrum CBD oil is the better alternative, as it provides patients the ancillary benefits associated with the many other cannabis compounds. However, important to note, is the issue of what medical conditions are best treated by either pure or full spectrum CBD oil, given the research is in its infancy.
