The "Full-Spectrum" Difference: Why To Look Out For This Term On A Label

Full-spectrum hemp oil (not to be confused with hemp seed oil) is an extract only derived from hemp. Hemp is the term for a cannabis plant with 0.3% tetrahydrocannabinol (THC) or less—not enough for mind-altering effects. In contrast, a CBD oil can be extracted from either hemp or marijuana. Marijuana is the term for cannabis plants with higher levels of THC.

When you take a full-spectrum supplement rather than a CBD isolate product, the hemp plant's hundreds of compounds have a way of working together to boost the product's overall benefits. Researchers call this synergy the entourage effect1: when cannabis compounds work together, they're more powerful than any one cannabinoid on its own. "I think about it in a sports metaphor, where you've got one star player, but you need the team," explains renowned integrative physician Robert Rountree, M.D. "It's the mix that's important."

So what are all those compounds, and what do they do? First, cannabinoids affect the body's endocannabinoid system, the body's "master regulatory system," which plays a role in 2maintaining the immune, digestive, and central nervous systems. 

Our bodies actually make their own endocannabinoids to help keep us in balance or homeostasis. But researchers theorize that sometimes we become deficient in endocannabinoids3, which can lead to chronic conditions such as irritable bowel syndrome or migraines. When taken as a supplement, phytocannabinoids, which come from plants, may be able to help ease some of the symptoms by helping our endocannabinoid system perform its delicate balancing act.*

One of the most talked-about and researched phytocannabinoids in hemp oil and CBD oil is, of course, CBD. But that's just the tip of the iceberg: Scientists are still studying just how many cannabinoids can be derived from hemp and what their capabilities are individually, collectively, and in various combinations.  

What's more, cannabinoids are just some of the beneficial compounds present in cannabis that end up in a full-spectrum product. "We know that phytocannabinoids are more effective and better tolerated when taken together and in concert with their co-occurring terpenes, flavonoids, and other phytochemicals than when they are taken in isolation," explains Jessica Knox, M.D., MPH, co-founder of the American Cannabinoid Clinics and a preventive medicine physician.

Terpenes4, responsible for the aroma of cannabis, enhance how we process the plant's many cannabinoids. And flavonoids5—also abundant in tea, fruits, veggies, and more—are phytonutrients known to have anti-inflammatory and anti-oxidative effects.
