Can CBD help reduce Anxiety?

Anxiety is a condition that affects about 18% of the US adult population and 25% of children ages 13 to…



CBDa (Cannabidiolic Acid) is the raw, non-intoxicating “parent” to CBD. CBDa is made by hemp plants as they mature and is the primary cannabinoid in most raw hemp flower. Since there is no heating involved during our CBDa manufacturing process, our solutions contain naturally occurring terpenes which contribute to an enhanced entourage effect.

Preclinical trials have shown CBDa has strong inhibitory effects on enzymes that are responsible for inflammation (COX-2), and stimulatory effects on a key mood regulating center in the brain (5HT-1a). 

CBD (Cannabidiol) is the neutral “child” of CBDa. When we heat the raw hemp flower to just the right temperature, for just the right amount of time, we are able to convert the acidic CBDa into the neutral CBD. 

In preclinical trials, CBD has demonstrated far reaching effects on the endogenous cannabinoid system (ECS). 

The ECS is in charge of balancing and maintaining the body’s homeostasis through systems that regulate sleep cycles, appetite, memory, pain sensation, inflammation, immune function and much more.

Most people have found that CBD works best for balancing their sleep cycles but we do have a few customers that prefer CBDa because they felt it alleviated their pain caused by inflammation.

Most of our customers have had the best subjective success using CBDa for calming their minds. 

Our CBDa as an anti-inflammatory and pain and tension balm as a muscle or joint rub are what most of our customers have reported to have the most benefit with these issues.

There are very small amounts of THCa and THC in our products (not enough to be intoxicating). This is highly beneficial in most situations, but in rare instances it can lead to false positives for marijuana use. It does depend how sensitive the testing equipment is and how your body processes cannabinoids whether or not the THC will show up. In dealing with thousands of customers this has not been an issue, but it is best to check what kind of drug test will be required.

When stored consistently in a cool, dark place, you can expect our oils to stay good for at least 12 months after purchase. The CBDa will slowly convert to CBD over time. If stored in a cool dark place, after 16 months your Circle Labs CBDa will be roughly 66% CBDa and 33% CBD.  We make small batches and do not keep a large inventory so you can be assured that when you purchase a bottle of Circle Labs Whole Flower CBD or CBDa Oil from us or any of our suppliers, it has been freshly made

We selected organic, extra virgin olive oil as our carrier for its superior shelf stability and flavor, and also out of admiration for its long standing traditional use. Extra virgin olive oil contains a wide range of beneficial phytonutrients and fatty acids of its own. This diversity provides powerful nutritive benefit, and shelf stability that some of the most healthy cultures in history have relied on for at least 4,000 years (probably more like 6,000).
