When you buy CBD online, stick to vendors who invest in third-party lab tests and provide only reputable, US-manufactured products. Hemp oil is expensive to produce at the highest purity and quality standards, so you should steer clear of any suspiciously cheap offer or product, as it may contain substances you don’t want to ingest. Check out our best CBD oil page to discover some of the most popular product types.
Even though high-strength CBD oils are more expensive than lower concentrates, they work out to be more cost-effective and longer-lasting because you’ll need fewer drops to obtain the same effect. For example, a single drop of Love Hemp’s 40% CBD oil contains 20mg of CBD, that is 4 times more than a 10% tincture, which provides just 5mg per drop. If you’re looking to take a high dose, stronger concentrates will also make it easier to achieve your desired dose (fewer drops to count!).
CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
Another major reason why CBD oil has been positively received in some parts of the medical community is its apparent effect on cancer and tumor growth.A study done by the researchers of the Institute of Toxicology and Pharmacology, University of Rostock, Germany recommends the use of CBD oil (even direct injection into tumors) to eliminate or reduce the size of the tumors. The antioxidants in CBD hemp oil also provide anti-mutagenic properties and lower users’ risk of cancer.
Transparency: Fab’s website features third-party lab results for most products. They only have a lab test for one of their tinctures though (which shows results for cannabinoid potency, as well as contaminants like pesticides). Customer service pointed out that the same CBD oil is used for all their products, but since potencies do vary, we appreciate companies that show potency testing for all products.
The NCBI study does mention some potential side effects for cannabidiol, such as the inhibition of hepatic drug metabolism and decreased activity of p-glycoprotein. CBD can indeed interact with a series of pharmaceuticals, as it inhibits the activity of some liver enzymes called cytochrome P450. This family of enzymes metabolizes most of the pharmaceutical drugs used to treat humans.
