Take hemp oil for example. Hemp oil is actually hemp seed oil. It has lots of benefits—but is missing one ingredient that some sellers seem to hope you don’t realize—it is missing CBD!
Hemp seed oil is a nutritious oil—it contains:
Hemp seed oil has one of the highest amounts of polyunsaturated fats (PUFAs) in any commercially available plant oil. PUFAs have been linked to decreased risks of cardiovascular disease, cancer, rheumatoid arthritis, hypertension, inflammatory, and autoimmune diseases.  The ratio of omega-3/omega-6 oils is about 1:2 – 1:3, much better than other plant oils. These fats may also reduce inflammation, cholesterol, heart disease, and benefit the growth and development of the fetus and young child., 
Antioxidants and plant polyphenols also have health benefits for heart health, healthy nervous and digestive systems and a healthy immune system.
Hemp seed oil does not have high levels of CBD. Trace amounts are sometimes found in some batches, but this is likely due to contamination with older parts of the plant. 
It is best to get cold-pressed hemp seed oil —no heat should be used in the processing, just as with olive oil. The color ranges from clear green/yellow to dark green. It should be used at room temperature because it smokes very quickly if you are trying to sauté or cook something with it on a stovetop. Instead, it can be used in dressings, smoothies, dips, pesto and sauces.
Hemp Seed oil also has benefits for the skin—it hydrates, smooths, is anti-inflammatory and doesn’t clog up pores, so it is used to benefit acne, rashes, dry skin, and may be beneficial in inflammatory skin diseases like eczema and psoriasis.
CBD oil, on the other hand, is derived from a mature hemp plant and not the seeds. CBD oil can also be made from purified CBD which is then added to a carrier oil such as coconut oil, MCT (Medium Chain Triglyceride) oil, glycerin or…hemp seed oil! It can also be contained in a mixture of these oils.
CBD oil can be safely used over a relatively wide range of doses—we at LeafReport always recommend that you start at a low dose and slowly increase that dose until your health goal is achieved. Side effects are relatively mild but can include a dry mouth, diarrhea, drowsiness and fatigue. It is important, though, to know that CBD can interact with prescription medications including SSRIs and blood thinners. Talk to your pharmacist for the best information.
CBD oil is best taken under the tongue (sublingually) because it is best absorbed through the mucus tissues under the tongue. Keep the oil under your tongue for 30-60 seconds for best results.
