What Is THCa? 

One rare cannabinoid that’s making waves it THCa. But what is it exactly? THCa, or tetrahydrocannabinolic acid, is a naturally occurring compound found in raw cannabis plants. It is the precursor to THC, the well-known psychoactive cannabinoid responsible for the "high" associated with cannabis use. THCa is typically found in the raw cannabis plant in higher quantities than THC. However, it isn’t psychoactive until it is decarboxylated, or heated, through processes such as smoking THCa flower, vaping, or cooking. One of the interesting aspects of THCa is its potential therapeutic benefits. Research suggests that THCa may have anti-inflammatory, neuroprotective, and antiemetic properties. It may also show promise in the treatment of conditions such as epilepsy, cancer, and neurodegenerative diseases. Learn more about THCa here.

What is THCv? 

What is THCv? Also known as tetrahydrocannabivarin, THCv is another lesser-known cannabinoid found in small quantities in certain cannabis strains. THCv is particularly interesting because of its unique characteristics. This cannabinoid provides stimulating effects and may act as a mood enhancer, promoting focus and creativity. This makes it the perfect choice for those looking for a more uplifting cannabis experience. 

Studies have also shown that THCv can act as an appetite suppressant. It may also help regulate blood sugar levels, aid with weight loss, and improve insulin sensitivity. These unique properties and effects are especially exciting for researchers and cannabis enthusiasts alike. Learn more about THCv here.

So what is PHC weed? Our Phd Chemists referred to this compound as PHC, which stands for Proprietary Hydrogenated Cannabinoid. PHC is now formally known as 4-Hydroxycannabidiol, or H4CBD for short. H4CBD is the hydrogenated form of CBD. You’ll also notice that our packaging has H4CBD in place of PHC but not to worry, we’re referring to the same compound. Learn more about PHC here

H4CBD Cannabinoid Effects

PH4CBD 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. This can be attributed to the entourage effect which you can learn more about here.
