Conversely, to preserve most of the plant’s trichromes – these are the cannabinoids, terpenes, and flavonoids – look for Supercritical (or subcritical) CO2 extraction. This method uses carbon dioxide under high pressure and extremely low temperatures to isolate, preserve, and maintain the purity of the medicinal oil. While this method is more expensive and involves complex equipment and expertise, it ensures quality.
Watch Out For: Hemp grown in the European Union (EU) and China. Even in countries with agricultural regulations, the list of approved pesticides is far from safe. Thus you are really relying on the specific company’s ethical standards when it comes to hemp cultivation. The reason this is such a big deal with hemp when compared to other plants, is that hemp is a dynamic accumulator plant. Dynamic accumulator is a term used to describe plants that gather minerals – both good and bad – from the surrounding soil and store them in its tissues. So if you’re growing a hemp plant with petroleum-based pesticides in soil that contains heavy metals…you’re inevitably going to have a hemp plant containing both toxic pesticides and heavy metals. This is why many people have poor experiences when first trying CBD – you buy your vegetables organically, why not your hemp? The presence of these toxins is not regulated by any agency and they will end up in your CBD oil if you don’t purchase from the correct company. We like Ambary Gardens because they ensure that all of their CBD products are produced from organically and sustainably grown hemp without the use of pesticides.
“The need for enhanced bioavailability of the CBD phytonutrient is paramount”, adds Moriarity, “but tricky to accomplish without synthetic chemicals.” Most CBD products do not offer any bioavailability optimization, so 90 percent of the CBD is lost to first-pass effect, a phenomenon of drug metabolism whereby the concentration of a drug is greatly reduced before it reaches systemic circulation.

If you are vaporizing CBD-dominant strains of cannabis, bioavailability is through the alveoli, tiny sacs in the lungs, clarifies Kilham. If you are taking CBD strain capsules, he suggests eating some fat or oil, like a handful of nuts or some full-fat yogurt, to improve absorption and bioavailability. Cannabinoids are fat-loving molecules. They are taken up readily into the small intestine with a bit of dietary fat.
For some, having more than trace amounts of Tetrahydrocannabinol (THC) might not be a big deal, but if you’re being drug tested at work, operating heavy machinery, or fall into a number of other categories, you may want to keep the THC to a bare minimum. In order to qualify as a legal hemp product, CBD oil must contain less than 0.03% THC. Look for CBD oil certified to have low levels of, or zero, THC in them. Many reputable sellers do offer products that have absolutely no THC in them at all, so if you are concerned about keeping even trace amounts of TCH out of your body, it is best to look for those products and sellers.
