Whereas marijuana contains both THC and CBD, hemp contains almost exclusively CBD — THC occurs only in very trace amounts. Remember, though, that there are many varieties of marijuana and hemp plants, and their concentrations of THC and CBD vary. Those with high THC are used primarily for recreational use; plants with low or no THC and high CBD are best for medicinal use. Only cannabis with less than 0.3% THC can be legally classified as hemp.
Unrefined hemp oil does not have a very long shelf life. The oil quickly goes rancid, unless it is stored in dark containers in a refrigerated environment. People who use unrefined hemp oil generally purchase it in small amounts so that it will not become rancid. The oil is also not suitable for cooking, because it has a very low smoking point. Refined hemp oil is much more shelf stable, although many of the benefits of it are not present after refining.
Medterra is the only CBD brand I order from. I was a little skeptical about CBD at first but tried it on the advice of my doctor. I suffer from chronic pain and the only thing that helps the pain is this oil. It really helps with my back pain and I use the tincture and the new Cooling Cream. And the best part is that there are no side effects I dont feel drowsy or unfocused and it doesnt interact with other medications. And Medterra is a fantastic company. One time the shipping of my oil was delayed for some reason and they sent it using express shipping without an added cost Their service is great.
