What is PHC? Everything To Know About H4CBD

1 comment

Gone are the days of marijuana products with just THC or CBD. As the hemp industry continues to thrive and evolve, researchers have unearthed an abundance of cannabinoids. These include Delta 8, HHC, Delta 10, THCh, THCp, THCv, THCm, and the list goes on. One of the latest compounds to hit the scene is PHC. If you want to learn more, you’ve come to the right place. We’re going to tell you everything you need to know about the PHC cannabinoid including what it is, its effects, and where to find the best PHC products on the market.

PHC / H4CBD Background

As leaders in the hemp field, we are continuously researching and making new discoveries. One day, when our PhD Chemists were hard at work in our lab, they realized they chemically stumbled upon a new compound. At the time, we called it PHC, to stand for Proprietary Hydrogenated Cannabinoid. After gaining more traction in popularity, the cannabinoid PHC is now formally known as tetrahydrocannabidiol, or H4CBD for short. We’ve been able to incorporate this new compound in some of our highly acclaimed premium blends. For the sake of clarity and continuity, we’ll call it PHC in this post. Moving forward you may notice our new packaging refers to it as H4CBD. Don’t fret, we're referring to the same cannabinoid. 

What Is The Cannabinoid PHC?

So what is PHC? PHC or H4CBD is CBD (Cannabidiol) that has had one of the hydrogens at position 4 of the pentyl chain replaced by a hydroxy group, a process called hydrogenation. In other words H4CBD is a hydrogenated form of CBD, much like how HHC is a hydrogenated form of THC. PHC / H4CBD is actually one of the main metabolites of CBD by the human liver microsomes. This is similar to how 11-Hydroxy-THC is a main metabolite of THC. Because any alteration in a natural compound is regarded as a synthetic form of the original, H4CBD is considered a synthetic cannabinoid.

What Effects Does the Cannabinoid PHC Bring?

PHC is a mildly psychoactive cannabinoid. Its effects are sativa-like, inducing uplifting, slightly euphoric feelings. Reported users have noted its prominent therapeutic effects, which we’ll get more into later. PHC, or H4CBD isn’t known to have a great amount of psychoactive effect on its own, however when combined with certain other cannabinoids, it can intensify the overall effects. We can attribute this to the entourage effect.

A great example of the entourage effect is our Euphoria blend. When our PhD Pharmacist combined H4CBD, or PHC, with the other cannabinoids of this highly appraised blend, the effects epitomize euphoria. Of course, cannabinoids’ effects may vary from person to person. But overall here are some of H4CBD’s most reported effects: 

  • Happiness
  • Relaxed
  • Mild feelings of euphoria
  • Anxiolytic properties (reduces anxiety)
  • Relief

PHC Potential Benefits

PHC (H4CBD) also has potential medicinal benefits, as it has antioxidant and anti-inflammatory properties. Many of its users often experience a distinct effect that can provide intense relaxation and relief from physical tension. This is what makes it a key component of our Recover blend, an all encompassing cannabinoid blend that can help ease body aches and muscle tension.

Where To Find Delta 8 Near Me

Another incredibly popular cannabinoid is Delta 8 THC. It’s actually one of the first hemp-derived cannabinoids to make waves in the industry after the 2018 Farm Bill was signed into law. And for good reason too, it’s known to provide relaxing, euphoric effects. In fact, one study’s participant dubbed it “Delta-9-THC's nicer younger sibling” as many report it is less likely to cause anxiety than standard THC.

We understand the struggle of finding consistent, high quality Delta 8 products like disposable vapes, vape cartridges, edibles, prerolls, and more.
