Hemp oil and hemp seed oil are not always the same thing, and the confusion between them is one of the most common mix-ups in the wellness market. Hemp seed oil comes exclusively from the seeds of the hemp plant and contains virtually no CBD or THC. “Hemp oil,” on the other hand, is a vague term that sometimes means hemp seed oil and sometimes means an extract from the flowers and leaves of the hemp plant, which can contain 12% to 18% CBD. The difference matters for your health, your wallet, and what you’re actually putting in your body.
Where Each Oil Comes From
Hemp seed oil is made by cold-pressing the seeds of the cannabis sativa plant. The seeds are mechanically squeezed, typically with a screw press, without chemical solvents. This process is similar to how olive oil or sunflower oil is made. The result is a nutty, greenish cooking and skincare oil with a nutritional profile closer to flaxseed oil than to any cannabis product.
What gets labeled “hemp oil” in stores and online is less straightforward. Some manufacturers use the term as a synonym for hemp seed oil. Others use it to describe an extract pulled from the stalks, leaves, and flowers of the hemp plant, which is where cannabinoids like CBD actually concentrate. These extracts use different methods entirely, often involving CO2 or ethanol to pull out the active compounds. The two oils come from different parts of the same plant, contain completely different compounds, and serve completely different purposes.
Cannabinoid Content: Nearly Zero vs. Significant
Hemp seeds contain only trace amounts of cannabinoids, picked up incidentally when the seeds contact other parts of the plant during harvesting. Lab analysis of commercial hemp seed oil products shows CBD levels typically below 0.003% (about 28 parts per million at most) and THC levels below 0.017%. Many tested products registered at the lowest detectable threshold for both compounds. In practical terms, hemp seed oil will not produce any cannabinoid effects whatsoever.
CBD-rich hemp extract is a different story. The flowers and upper leaves of hemp plants average 12% to 18% CBD, and extracts concentrate these compounds further. If you’re buying a product specifically for CBD’s reported effects on pain, anxiety, or sleep, hemp seed oil won’t deliver. If you see a product on the shelf labeled “hemp oil” priced similarly to a bottle of cooking oil, it’s almost certainly hemp seed oil, not a CBD extract.
Nutritional Profile of Hemp Seed Oil
Hemp seed oil’s real value is nutritional, not cannabinoid-related. It contains 70% to 90% polyunsaturated fatty acids, making it one of the most unsaturated plant oils available. The dominant fatty acid is linoleic acid (an omega-6) at 50% to 70%, followed by alpha-linolenic acid (an omega-3). The omega-6 to omega-3 ratio sits at roughly 3:1, which nutritionists consider favorable for heart health. Most Western diets skew that ratio closer to 15:1 or 20:1, so hemp seed oil can help rebalance your intake.
Beyond the basic fatty acids, hemp seed oil contains gamma-linolenic acid (GLA) at 0.5% to 6% and stearidonic acid at 0.3% to 2.5%. These are less common fatty acids that play roles in reducing inflammation. The oil also provides vitamin E at levels comparable to soybean and sunflower oil (76 to 92 mg per 100 grams) and has notably high plant sterol content. The seeds themselves are roughly 25% to 30% oil, 25% to 30% protein, and 30% to 40% fiber by weight.
Cooking and Skincare Uses
Hemp seed oil has a smoke point of about 330°F (165°C), which is relatively low. It’s best used as a finishing oil drizzled over salads, soups, or grain bowls rather than for frying or high-heat sautéing. Heating it too much turns it bitter and degrades the delicate polyunsaturated fats you’re eating it for in the first place. It works well in smoothies, homemade dressings, and as a substitute for other nut or seed oils in cold preparations.
For skin, hemp seed oil moisturizes without clogging pores, making it suitable for most skin types including oily and acne-prone skin. The GLA content gives it anti-inflammatory properties that can help calm irritation, redness, and conditions like psoriasis. A randomized clinical trial found that dietary hemp seed oil reduced symptoms of atopic dermatitis (eczema) after 20 weeks of use. It’s widely used as a carrier oil in skincare formulations and can be applied directly to the skin.
Why the Labeling Is So Confusing
The ambiguity between “hemp oil” and “hemp seed oil” isn’t accidental. Amazon, for example, prohibits the sale of anything labeled “CBD” on its platform but allows products labeled “hemp.” Some CBD companies have responded by relabeling their CBD oils as “hemp oil” to sell on Amazon. One company, Cornbread Hemp, publicly described listing its CBD oil under the name “Hemp Oil” with no mention of CBD on the label to comply with Amazon’s policies. This means a product called “hemp oil” on a major retail platform could be a $8 bottle of seed oil or a $40 bottle of CBD extract, and the front label alone won’t tell you which.
The FDA has added a layer of clarity on the food side. In 2018, the agency confirmed that hulled hemp seeds, hemp seed protein powder, and hemp seed oil are Generally Recognized as Safe (GRAS) for use in human food. These ingredients contain only trace cannabinoids. But the FDA has not extended this status to CBD or THC. Adding CBD to food remains prohibited under federal law. So if a food product contains “hemp oil,” it should legally be hemp seed oil, not a CBD extract.
How to Tell What You’re Actually Buying
The ingredient list is more reliable than the front label. Hemp seed oil will be listed as “cannabis sativa seed oil.” CBD extract will typically appear as “cannabidiol,” “full-spectrum hemp,” “PCR hemp extract,” or “phytocannabinoid-rich hemp extract.” If neither of those descriptors appears clearly, check for a CBD milligram count on the label. A product advertising 500mg, 1000mg, or similar dosing is a CBD product. A product listing only nutritional facts like fatty acid content is a seed oil.
Price is another reliable signal. Hemp seed oil is an affordable cooking oil, typically a few dollars per ounce. CBD extracts cost significantly more due to the specialized extraction process and the value of the cannabinoid content. If a “hemp oil” product seems surprisingly cheap for a CBD product, it’s almost certainly hemp seed oil. If it seems surprisingly expensive for a cooking oil, look more carefully at the label for cannabinoid content you might be paying for without realizing it.
