Currently, the only CBD product approved by the Food and Drug Administration is a prescription oil called Epidiolex. It's approved to treat two types of epilepsy. Aside from Epidiolex, state laws on the use of CBD vary. While CBD is being studied as a treatment for a wide range of conditions, including Parkinson's disease, schizophrenia, diabetes, multiple sclerosis and anxiety, research supporting the drug's benefits is still limited.
Due to the anti-inflammatory properties of cannabidiol, insulin resistance (the chief metabolic problem for patients with type 2 diabetes) is reduced, leading to a better prognosis thanks also to the lower incidence of dead tissue. Ever since the discovery of CBD in the 1990’s, speculation existed to its effect on other types of receptors (not just cannabinoid receptors) which could be manipulated and included in the treatment of some cardiovascular diseases like atherosclerosis. In light of these speculations, researchers at the University of Tel Aviv (walking in the footsteps of the “father” of cannabinoid research, Dr. Raphael Mechoulam) demonstrated a 30 percent blood flow increase in rodents with areas of dead tissue in the heart muscle.[22]
Using rigorous review methodology, Gloss and Vickery conclude that based on the low quality of the reports available, there is insufficient data available to draw any conclusions regarding the efficacy and or long-term safety of CBD in treating epilepsy (11). From the data available, it does appear that daily doses of 200 to 300 mg were safe in this small group of patients for a short period of time (14).
The list of cannabinoids currently comprises 113 entries, with more and more additions each year. Of these 113, by far the best documented are tetrahydrocannabinol and cannabidiol (in this order), with the two also being the most abundant constituents of the cannabis plant. In a typical chemical isolation process, cannabidiol makes up a little under half of the entire extract.
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
But it also requires careful research before making a purchase. Because the cannabis plant readily absorbs pesticides, heavy metals and other chemicals that are in the soil and water, it’s so important that cannabis plants are frequently tested while they are growing. And it’s up to manufactures to test CBD products, too. When you are shopping for CBD oil, look for products that have been tested for contaminants and for CBD vs. THC levels.

Tinctures – Typically tinctures are small glass or plastic “dropper” bottles that have cannabidiol oil mixed with a preserving solution such as alcohol. Tinctures were very a very common way to ingest botanical oils prior to the industrial revolution and are experiencing a resurgence in popularity as more people are looking for natural remedies. Tinctures with droppers allow you to put a few drops in your tea, under your tongue, or to bake the oil directly into your food.
