I did an analysis of 10 diffirent CBD oils and Medterras 3000mg bottle is the most cost effective per mg. Their product also appears the safest with where they source their materials and how they conduct their business. There were no issues with the ordering process and I received my product in a timely fashion as well. There is almost no taste to the oil and I take 25 ml (25 mg) twice daily with excellent results. I finely feel calm and sleep well. I am also able to focus better and get more done each day, which was an unexpected bonus. I was very sceptical about CBD at first. I have tried everything for my anxiety, and although some of the traditional drugs work, their side effects negate any benefits. I was feeling very frustrated and hopeless and ordered the CBD out of desperation. Im glad I took the chance. Well, it wasnt really a chance; I read every research article I could get my hands on and was swayed by the emerging data. I guess it was more of a leap of faith in a product that had such high claims and no healthcare gatekeepers. I have had no side effects though. The only negative is the cost.
Cannabidiol also is found in cannabis plants, but usually at much lower levels, unless the cultivar has been bred for a high CBD content. The primary source of most CBD on the market today is from the agricultural hemp plant. Over 10,000 years ago, hemp was one of the first plants spun into fiber and it is also one of the fastest growing plants in the world.
In the USA the legal definition of “industrial hemp,” per Section 7606 of the Agricultural Appropriations Act of 2014, is “INDUSTRIAL HEMP — The term ‘‘industrial hemp’’ means the plant Cannabis sativa L. and any part of such plant, whether growing or not, with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis.”
Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner. In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity. A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.
