Finally, in general, we almost always recommend full spectrum tinctures over supplements made from isolates (extracts of CBD alone). Full-spectrum or whole plant tinctures take advantage of the ‘entourage effect’ that comes from combining all the naturally occurring chemicals found in the hemp plant. Isolates are great for cooking with CBD or consumers that are especially sensitive to the taste of hemp extract, but some research suggests they may be less effective for certain uses than full spectrum extracts. All but two of the brands below are made from full spectrum hemp, and the exceptions are clearly noted.
Watch Out For: Companies who won’t disclose their extraction method or utilize hydrocarbons like butane and propane. These substances are toxic in high amounts and even with proper purging, most hydrocarbon extracts contain residual solvent. Other extraction methods do not result in a full spectrum extract – meaning they were not able to extract all of the beneficial compounds from the hemp plant (i.e. you don’t get the full range of benefits).
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.
