Black seed oil (also known as black cumin seed oil, black onion seed oil, or kalonji) is derived from the seeds of Nigella sativa, a small flowering shrub native to eastern Europe, the Middle East, and western Asia.
Hemp seed oil (sometimes simply called hemp oil) is made, you guessed it, from hemp seeds, a superfood revered for its high concentration of plant proteins, vitamins, minerals, and more. It’s extremely rich in omega-3 and 6, and, while less studied than olive oil, has also been shown to have a unique range of health benefits.
At RQS, we use olive oil as the main carrier oil in our standard CBD oils (available in 2.5%, 5%, 10%, 15%, and 20% concentrations). While it may not be as easy to digest and break down as MCT oil, we believe its unique health benefits make olive oil one of the best carrier oils for CBD.
Black Cumin Seed Oil
First and foremost, olive oil is extremely rich in oleic acid, a monounsaturated fat that has been shown to reduce inflammation  and, in some studies, even inhibit tumour cell proliferation  . Olive oil is also rich in omega-3 and 6 fatty acids, which are important components of cell membranes and precursors to many vital compounds that help regulate inflammation and blood pressure.
Olive oil is a staple in many people’s diets. In addition to being an incredibly tasty and versatile cooking oil/condiment, olive oil has been shown to have a wide variety of beneficial properties.
After discovering these seeds in the tombs of King Tutankhamun, scientists believe that black cumin seed has long played a central role in medicine and cooking. Studies suggest, for example, that black cumin seed oil is super rich in antioxidants  and may help relieve inflammation (when ingested or applied topically to the skin).
Carrier oils play a crucial role in CBD oils; chiefly, they help deliver the CBD, terpenes, and other beneficial compounds in cannabis extract into your body. Some of the most common carrier oils used in CBD products include:
If you’ve ever used a CBD oil, you’ve gotten more from the product than just cannabidiol (CBD). For multiple reasons, manufacturers need to put CBD into carrier oils. You should always check the label of your CBD product and know what’s in it.
Carrier oils may have health benefits all on their own, which you may then benefit from. For example, olive oil has gotten a lot of attention for its heart-healthy benefits.
Benefits of CBD Carrier Oils
One key reason for using a carrier oil is that they improve the bioavailability, which means they help your body absorb the CBD oil. CBD is fat-soluble, which means that it dissolves in oil rather than water. Fat-soluble substances are better absorbed when digested along with fat, even in small amounts.
Essential oils are sometimes used topically (on the skin) after being diluted by a carrier oil. Essential oils themselves, however, should never be used as a carrier oil.
First, like several other common carrier oils, it’s rich in omega-6 fatty acids. More than 70% of the fat content of grapeseed oil is made up of heart-healthy polyunsaturated fats, resulting in a heart-friendly reputation that it very much deserves.
In a 2013 study, researchers found that sunflower oil improved the level of skin hydration when applied by volunteers directly to the skin. For this reason, it’s a common carrier oil for CBD skin balms and lotions, such as this CBD balm from CBDfx and this moisturiser from Somnio CBD.
Another popular carrier oil, pomegranate seed oil is packed with antioxidants that make it one of the best carrier oils for CBD tinctures, capsules and topical products alike.
Like many other carrier oils, olive oil offers a range of health benefits. Studies show that it may help to reduce the risk of stroke. There’s also a comprehensive range of evidence showing that an olive oil-focused diet can reduce blood pressure and protect against heart disease.
First, sunflower oil is linked to improvements in skin health. Rich in vitamin E, sunflower oil may help to promote the growth of replacement skin cells, resulting in smoother, healthier skin that’s less affected by UV damage.
Overall, grapeseed oil is a healthy, effective carrier oil for CBD. You can find it in products such as this CBD balm from CBDfx, where it’s used alongside several other oils, as well as this CBD salve from Blue Moon Hemp.
Second, MCT oil has mild appetite-suppressing and weight loss benefits. In a 2014 study, it was found that MCT oil is linked to increased production of the peptides YY and leptin, both of which are associated with improved satiety and a reduction in appetite.
