Extraction: The method by which CBD oil is processed from hemp plants can be very telling. Some manufacturers extract and process the oil using toxic materials like propane or butane; in most cases, these oils are cheaply priced. Safer extraction and processing agents include ethanol, which cleans the hemp plant of unwanted toxins; and supercritical carbon dioxide extraction, which strips harmful materials from the plant by changing the carbon dioxide’s temperature and pressure settings.
Customer Service: It’s difficult to find contact information on Calm by Wellness’s website, and their email address is listed incorrectly in two places (we tried sending them an email but it was not delivered). We were, however, able to get a response through Facebook, and the company does offer free shipping and a generous 30-day return policy on all orders.
A major theme when reviewing the research on the best CBD for pain is the need for more large-scale clinical trials on CBD in isolation from other cannabinoids like THC. That’s not to say that THC is bad. It’s developed a stigma because it makes you high, which makes people think of hippies and the sixties and maybe your perennially stoned neighbor who clearly doesn’t have his stuff together. But THC also comes with a pretty respectable list of benefits. These range from antiemetic (anti-nausea) and anti-inflammatory effects to appetite stimulation.
In addition to all the benefits we’ve already discussed, CBD has been proven to have antioxidant and neuroprotective effects. This means that it helps repair the damage from oxidative stress, which is believed to be a primary cause of diseases like Alzheimer’s, Parkinson’s, ALS — even heart disorders and some forms of cancer. This is a hugely beneficial effect of CBD.
The tincture is available in three strengths: 500mg, 1,000mg, and 3,000mg. Prices range from $0.04 to $0.07 per mg, depending on the concentration, which makes the tincture very low-priced compared to oils from most competing brands. Medterra also offers a 30-day satisfaction guarantee and will issue full refunds for all returns. In addition to the tincture, Medterra also offers CBD capsules in 25mg and 50mg concentrations.
