Until recently, federal regulation in the U.S. meant that industrial hemp could not be cultivated for commercial use. It wasn’t until the 2018 Farm Bill that farmers could grow and sell hemp plant extracts—namely, hemp oil and CBD oil. Since then, these products have hit the market quickly and with much fanfare, but with increasing popularity comes increasing confusion. If you’re wondering about hemp, CBD, and the difference between the two, here are the top-level highlights.

Hemp vs. CBD: The basics.

For starters, let’s go over the differences between hemp and marijuana. These are two different plants from the same family: Cannabis. Cannabis plants contain a variety of different compounds called cannabinoids, the two most well-known (and most studied) are THC and CBD. THC has psychoactive effects, which means it can get you high and is found in high concentrations in marijuana plants. CBD does not have psychoactive effects, and is instead taken for stress management.*

Hemp oil extract, on the other hand, is an oil that’s made from the stalk, and/or flowers of the hemp plant and is rich in beneficial cannabinoid compounds. (It should not be confused with hemp seed oil, an omega-3 rich culinary oil made from pressed hemp seeds that does not contain cannabinoids.) CBD isolate oil,on the other hand, is an isolated extraction of one particular cannabinoid, cannabidiol. So the main difference between hemp oil and CBD oil is that CBD oil contains one type of cannabinoid, while hemp oil has a variety of them.ADVERTISEMENT

More on hemp oil.

Hemp oil is safe and legal: It must contain less than 0.3% THC, it is legal in all 50 states, and it will not make you feel you high even in large doses. (Repeat: Hemp oil will not make you high!)

What it will do is give you a dose of beneficial cannabinoids, including CBD. While CBD and THC are the most well-known cannabinoids, the hemp plant contains more than 140 different cannabinoids in total. In addition to the cannabinoids, hemp is also rich in organic compounds called terpenes that give the plant its smell and taste. Each of these cannabinoids and terpenes is associated with various benefits, like supporting sleep, digestion, and immune function.*

While each cannabinoid and terpene is beneficial on its own, all of these compounds are synergistic when taken together—a phenomenon called “the entourage effect.”* That’s what makes hemp oil extract so impressive. As a rich source of cannabinoids, hemp oil extract imparts the entourage effect, meaning you benefit from all the plant compounds.

OK, what about CBD oil?

CBD is the isolated extract of the specific cannabinoid cannabidiol from either the hemp or marijuana plant. CBD oil can be purchased in the isolate form, which means all of the other cannabinoids and terpenes have been filtered out or in the broad- or full-spectrum form, which means some or all of the other cannabinoids remain.

CBD oil that comes from the marijuana plant can contain higher concentrations of THC and get you high. This type of CBD oil is only legal in certain places or under certain circumstances, like with a medical marijuana card. CBD oil extracted from marijuana is often marketed as “cannabis oil.” CBD extracted from hemp contains less than 0.3% THC and will not get you high. 

A good way to tell if the CBD oil you’re purchasing is from hemp or marijuana is its availability. Most of the CBD oil that you can buy online and over the counter is the type that comes from hemp since the sale of high-THC CBD oil isn’t legal everywhere or outside of dispensaries.

While CBD does have benefits on its own, like stress management and enhanced sleep quality, it’s missing out on the synergistic benefits of the other cannabinoids and terpenes.* For this reason, many experts recommend whole-plant extracts rather than isolated CBD products. 

So, what’s the difference? 

Although they are marketed as being essentially the same thing, hemp oil extract and CBD oil extract do have some important differences. Hemp oil is a cannabinoid-rich extract that contains over 140 beneficial cannabinoids that produce the entourage effect, while CBD oil is an isolated extract of a single cannabinoid.

Decoding the label: What do the different spectrums mean?

Both hemp oil extract and CBD oil often have additional qualifiers, like full-spectrumbroad-spectrum, or isolate to give you an idea of what’s actually in the bottle.

Full-spectrum

Full-spectrum products contain all of the cannabinoids, including CBD, and terpenes in a nice little package—the way nature intended. Hemp-derived full-spectrum extract contains a very small amount of THC (less than 0.03%) and will not get you high. If you’re looking to reap the health benefits of the entourage effect, then full-spectrum hemp oil extract is what you want.* 

However, be aware that some marijuana-derived CBD oil (or cannabis oil) can be marketed as “full-spectrum CBD oil”; in this case, the product likely contains THC as well and might get you high. 

Broad-spectrum

Broad-spectrum CBD products contain all of the cannabinoids and terpenes except THC (and the minor THC cannabinoids, like THCa and THCv). These products are marketed as “THC-free” or “contains 0.00% THC,” and while that sounds good on paper, it does diminish some of the health benefits of the plant. 

Remember: The small amount of THC (less than 0.03%) in the full-spectrum hemp products won’t get you high, but it can enhance the entourage effect, amplifying benefits like stress management.* However, if you’re concerned about THC even in small doses, broad-spectrum is a good choice.

CBD isolate

CBD isolate is pure CBD. All of the other cannabinoids and terpenes have been filtered out and you’re left with only CBD. CBD isolates are often marketed as “pure” or “99% pure CBD.” 

Remember: While you’ll get plenty of CBD from these products, you’re missing out on all the health benefits of the other cannabinoids and terpenes.*

Even armed with all of this information, the marketing of many CBD products can still be misleading. So, it’s up to you to read labels closely and ask questions. When choosing a hemp-derived product, ask the manufacturer for a certificate of analysis (or “CofA”). A CofA shows the breakdown of all the cannabinoids in the product (and in what amounts) so you can be sure you’re getting what’s advertised. It’s best if the CofA was done by an unbiased third-party lab rather than directly by the manufacturer.

The bottom line.

The difference between hemp and CBD comes down to the cannabinoid content. Cannabinoids are beneficial plant compounds, including THC, CBD, and others. Both hemp oil and hemp-derived CBD products are legal and contain less than 0.3% THC, the psychoactive cannabinoid found in marijuana.

CBD oil is the isolated extract of a single cannabinoid, cannabidiol (CBD). Hemp oil is a whole-plant extract that contains all of the cannabinoids, including, but not limited to, CBD. When taken together, cannabinoids have a synergistic effect, called the entourage effect.

If you are looking to reap the benefits of the entourage effect, you should try full-spectrum hemp oil. If you are concerned about THC, even in small amounts, you should try CBD oil or broad-spectrum hemp oil.

This is what infectious disease experts and health organizations advise.

coronavirus-calendar

If you’ve tested positive for COVID-19 or have symptoms of the virus, the advice from the Centers for Disease Control and Prevention (CDC) is clear: Don’t leave your home unless you need medical care, and wear a cloth face covering over your nose and mouth if you must be around others, even at home. But how long should you keep taking these precautions after you’ve recovered from the coronavirus? 

Infectious disease expert Amesh A. Adalja, MD, senior scholar at the Johns Hopkins Center for Health Security in Maryland, tells Health that someone who has had COVID-19 stops being contagious approximately 10 days after symptom onset and after at least three days without fever. 

This is in line with the CDC‘s recommendation that a person diagnosed with COVID-19 can be released from isolation after 10 days from symptom onset and at least three days from fever resolution and improvement in respiratory symptoms. 

“This is supported by the WHO (World Health Organization), and I should add that no secondary spread or transmission has been seen after following this guideline,” epidemiologist Supriya Narasimhan, MD, division chief of infectious diseases and medical director of infection prevention at Santa Clara Valley Medical Center, in California, tells Health

However, like so many aspects of this virus, scientists are discovering new information all the time, and that can change official advice. For example, Dr. Narasimhan mentions a paper from China that suggests sicker patients may be contagious for up to 21 days—although it should be noted that details of this study aren’t yet fully available. 

“I bring this up to show that the information on this virus is constantly evolving and we learn more each day,” explains Dr. Narasimhan. “It is fair to say that sicker people will take longer to recover from their symptoms as well and will need to stay isolated to prevent transmission to others for a longer time period, until they have shown symptom improvement as per the CDC recommendation.” 

If you’ve had the coronavirus, it’s wise to check with your doctor and your local public health guidelines to establish when you can be released from isolation. Some places may be more conservative than the CDC—for instance, Santa Clara County Public Health advises remaining in isolation for 14 days from the onset of symptoms and at least seven days from fever resolution and improvement in respiratory symptoms. 

When you do go out in public or mix with other people after fully recovering from COVID-19, it’s still important to take preventative measures to help reduce the spread of the virus. 

“Follow what the CDC recommends,” says Dr. Narasimhan. “They should maintain a distance of six feet from others when possible, practice meticulous hand hygiene, and cover their nose and mouth with a face covering or mask.”

The face covering is “probably the most important of the three,” Dr. Narasimhan adds, because it provides “source control,” in other words, it prevents infectious particles that may come out of a person’s mouth when they cough, sneeze, or talk from getting into the surrounding airspace. 

“It’s important that all of us—including those who have recovered from COVID-19—maintain these safety precautions until we stop the spread of this pandemic,” says Dr. Narasimhan.

There’s nothing quite like biting into a juicy piece of fresh fruit. And on a particularly sweltering summer day, those thirst-quenching fruits can feel especially refreshing.

Well, according to new research, there’s another reason you might want to consider picking at a fruit plate (namely, one with berries): A recent study found that eating black raspberries (note: not blackberries) can reduce itchiness and inflammation associated with skin allergies. A promising milestone in the quest for healthy, soft skin.

First, what in the world is a black raspberry?

If you routinely pick up black raspberries at your local farmers market, feel free to skip on to the research at hand. But for many of us, the notion of a black raspberry may garner a collective, Huh? 

To put it simply, the fruit is a variant of the original red raspberry, commonly grown in the U.S. Pacific Northwest. As mentioned, they’re not quite the same as blackberries—while both may look similar upon first glance, black raspberries differ in texture and taste. First, the little drupelets on black raspberries are covered in tiny hairs (like your typical raspberry), while blackberries appear smooth on the surface. Black raspberries also have a hollow center (again, like its red counterpart), while blackberries usually have a white or green core. In terms of taste, many regard black raspberries as sweeter and less tart than blackberries. 

Even if you haven’t noticed the berry lining supermarket shelves, black raspberries have been long studied for their anti-inflammatory properties; in fact, previous studies have shown the fruit can manage chronic inflammatory diseases like ulcerative colitis, even having anti-carcinogenic effects. It only makes sense the berries could benefit skin inflammation as well. ADVERTISEMENT

What they found. 

To determine whether the berry has a place in skin care, researchers put a group of mice on a black raspberry diet, one that’s equivalent to a single serving per day for humans. After three weeks, they exposed these mice to common triggers that cause contact hypersensitivity (a condition that causes redness and inflammation in the skin, similar to contact dermatitis). The result? They found the mice’s swelling actually went down, compared to the control group.

An important point to note here: It’s not that the black raspberries were neutralizing the irritant, per se; rather, the scientists found that black raspberries help temper the immune system itself. The berries seem to affect certain cells that tell the immune system the perceived allergen is not a threat—and thus, no allergic reaction. As Steve Oghumu, Ph.D., senior author of the study and an assistant professor of pathology at the Ohio State Universityputs it, “A lot of the bad effects that we see are not always due to the pathogens or allergens themselves but are due to the way our body responds to these triggers. And so one way to manage these types of diseases is controlling that response, and that is one of the things black raspberries appear to be able to do.” 

What’s next?

Of course, this is only the beginning in terms of black raspberries’ effects on skin; Oghumu says a deeper dive is needed before we should stock up on black raspberries for skin health this summer. Specifically, he and his team are curious about what properties make those berries so anti-inflammatory. 

Nonetheless, it’s exciting to see how a simple, sweet berry can have such protective benefits for the skin. Oghumu agrees: “A lot of times, treatments are directly applied to the skin. It was interesting that the mere consumption of a fruit can achieve the same effects,” he says in a news release. And just in case you needed some more good news: These skin-healthy berries are in season.
