Hemp seed oil is extracted from hemp seeds. It contains fatty acids and other nutrients and is commonly used in food and skincare. CBD oil, on the other hand, is made from cannabinoid-containing parts of the plant or extracted compounds and is a different preparation.
Hemp seed oil is not a substitute for CBD oil, and ordinary hemp seed oil should not be assumed to have the same effects as cannabinoid products.
Research into hemp seed oil for pain is still developing. A 2024 clinical trial involving 90 people with knee osteoarthritis reported improvements in some pain and symptom measures after topical application. However, a single trial is not enough to establish effectiveness for other types of pain or for everyone.
How to Use Hemp Oil for Pain Relief
If you have a topical hemp seed oil product, follow its label and use it only as directed. The following steps can help you use a skincare oil carefully, without assuming it will treat the underlying cause of pain.
1. Check the product ingredients.
Read the label to identify whether the product contains hemp seed oil, CBD, or other active ingredients.
Look for:
-
A complete ingredient list.
-
Directions for topical use.
-
Manufacturer and batch information.
-
Expiry date and storage instructions.
-
Independent testing information, if available.
Avoid assuming that a product marketed as hemp oil contains CBD or has clinically established pain-relieving properties.
2. Perform a patch test.
Before applying a new oil to a larger area, test a small amount on a limited patch of skin.
-
Apply a small amount to an area of intact skin.
-
Leave it for the period recommended by the product instructions.
-
Check for redness, itching, burning, or swelling.
-
Stop using it if irritation develops.
Do not apply it to broken skin, wounds, or irritated areas unless a healthcare professional advises you to do so.
3. Apply it gently to the intended area.
If the product is labelled for topical use, apply it to clean, dry skin in the amount stated on the packaging.
You can spread the oil gently over the intended area without vigorous rubbing. Avoid contact with the eyes, mouth, and other sensitive areas.
Do not apply it under a heating pad, tight bandage, or occlusive dressing unless the manufacturer specifically permits this.
4. Follow the label rather than increasing the amount.
There is no universally established hemp seed oil dosage for pain relief. The amount and frequency used in one clinical trial should not be treated as a general recommendation.
If the label does not explain how to use the product, ask the manufacturer or a pharmacist rather than guessing.
Potential Benefits of Hemp Oil
Hemp seed oil has properties that make it useful in some skincare and nutritional contexts. Those properties should be distinguished from evidence that it relieves pain.
1. Skin moisturization
Hemp seed oil contains fatty acids, including linoleic acid and alpha-linolenic acid. These contribute to its use as an emollient in skincare formulations.
When used as a topical skincare ingredient, it may help soften skin and reduce the feeling of dryness. Moisturising the skin, however, is not the same as reducing inflammation inside a joint or treating an injury.
2. Potential relevance to joint discomfort
The 2024 trial of topical hemp seed oil in people with knee osteoarthritis found improvements in pain scores and some measures of symptoms compared with placebo.
However, the researchers did not find a corresponding advantage for every measured outcome. The 2025 living systematic review also judged the overall evidence for this particular product as insufficient because it was based on a single relatively small study with limitations.
This means topical hemp seed oil is an area of research, not an established treatment for osteoarthritis.
3. Nutritional fatty acids
Hemp seed oil is also used as a food oil. Its fatty acid composition makes it a source of dietary unsaturated fats.
Consuming a nutritious oil may have a place in a balanced diet, but there is no established evidence that eating hemp seed oil directly relieves joint pain, back pain, or muscle soreness.
Hemp Seed Oil vs. CBD Oil for Pain
Feature
Hemp seed oil
CBD oil
Main source
Hemp seeds
Cannabinoid-containing plant material or extracted CBD
Main components
Fatty acids and other seed constituents
Cannabidiol, with composition varying by product
Typical use
Food and skincare
Formulations marketed for cannabinoid use
THC/CBD
Seeds do not naturally contain these compounds, though traces can occur through processing.
May contain CBD and potentially THC, depending on formulation
Pain evidence
Limited evidence for topical hemp seed oil in knee osteoarthritis
Research varies by product and pain condition.
Key consideration
Do not assume it acts like CBD.
Check product quality, safety, and medication interactions.
The FDA notes that hemp seeds do not naturally contain THC or CBD, although trace amounts can be picked up during harvesting and processing. Its conclusions about hemp seed ingredients in food do not establish pain-relief effects.
Which Types of Pain Have Been Studied?
Different pain conditions have different causes, so results from one condition cannot automatically be applied to another.
-
Knee osteoarthritis: One trial has investigated topical hemp seed oil, but the evidence remains insufficient for a general treatment recommendation.
-
Muscle soreness: There is not enough clinical evidence to recommend hemp seed oil as a treatment for muscle soreness.
-
Back pain: Evidence specific to hemp seed oil for back pain is lacking.
-
Nerve pain: Studies of cannabinoid medicines are not equivalent to studies of hemp seed oil. Results depend on the cannabinoid formulation and condition.
For persistent pain, diagnosis matters. A topical oil should not delay assessment of an injury, inflammatory condition, or other underlying cause.
Tips for Using Hemp Oil Safely
Before incorporating a hemp oil product into your routine, consider these practical precautions.
-
Choose the correct product. Check whether you are buying food-grade hemp seed oil, a topical skincare oil, or a CBD-containing product.
-
Check for skin sensitivity. Fragrances, essential oils, and other ingredients may cause irritation even if hemp seed oil itself is tolerated.
-
Avoid unverified medical claims. Be cautious of products promising to cure arthritis, eliminate inflammation, or provide immediate pain relief.
-
Do not replace prescribed treatment. Speak with a healthcare professional before changing medication or an existing pain-management plan.
-
Seek advice about CBD products. CBD can interact with medicines and has been associated with liver injury and other adverse effects.
Who should be particularly careful?
People who are pregnant or breastfeeding, those taking regular medicines, and people with chronic medical conditions should seek professional advice before using medicinal hemp or CBD products.
If pain is severe, follows a significant injury, comes with fever or swelling, or is accompanied by weakness or numbness, seek appropriate medical assessment rather than relying on an oil.
Common Mistakes to Avoid
Confusing hemp seed oil with CBD oil: The names are sometimes used interchangeably in marketing, but the products have different compositions and evidence.
Assuming "natural" means "risk-free": plant-derived products can still cause skin reactions, interact with other substances, or have quality-control problems.
Using more than directed: Applying larger amounts does not establish better results and may increase irritation or exposure to other ingredients.
Expecting immediate results: There is no established time frame for hemp seed oil to relieve pain. Do not interpret a lack of immediate improvement as a reason to increase the amount.
Ignoring persistent symptoms: Pain that continues, worsens, or interferes with everyday activities deserves an assessment of its cause.
What Does the Research Say?
The current evidence needs to be interpreted carefully.
A 2024 randomized controlled trial compared topical hemp seed oil, diclofenac gel, and placebo in 90 people with knee osteoarthritis over two months. Some pain and symptom measures improved more in the hemp seed oil group than in the placebo group, but not every outcome differed.
A 2025 systematic review considered this study alongside the wider research on cannabis-related treatments for chronic pain. It concluded that evidence for topical hemp seed oil remained insufficient, given the limited number of studies and their methodological limitations.

The practical takeaway is that hemp seed oil has a possible research role in topical care, but more high-quality trials are needed before its effectiveness, optimal application, and long-term safety for pain can be established.
6. FAQs
1. Can hemp oil relieve pain?
There is limited research suggesting topical hemp seed oil may improve some knee osteoarthritis symptoms. There is not enough evidence to establish it as a reliable treatment for pain generally.
2. How often should I apply hemp oil for pain?
There is no universally established application frequency for pain relief. Follow the directions on your specific topical product and ask a healthcare professional if the instructions are unclear.
3. Is hemp seed oil the same as CBD oil?
No. Hemp seed oil is extracted from the seeds and is mainly used as a food or skincare oil. CBD oil contains cannabidiol, a cannabinoid with a different composition and safety profile.
4. Can I consume hemp seed oil for joint pain?
Hemp seed oil can be used as a food ingredient, but there is no established evidence that consuming it treats joint pain. Dietary use should not be confused with a clinical pain treatment.
5. Can hemp oil be applied directly to the skin?
A product specifically labelled for topical use can generally be applied according to its directions. Perform a patch test first and avoid damaged or irritated skin.
6. Does hemp oil contain THC?
Hemp seeds do not naturally contain THC, although traces can be introduced during processing. Products made from other parts of the plant may have different cannabinoid profiles. Check the specific product's composition.
7. Is hemp oil safe for everyone?
No product is guaranteed to be suitable for everyone. Skin irritation and product-quality issues are possible, and CBD products have additional risks, including potential drug interactions and liver injury.
8. Can hemp oil replace pain medication?
Hemp oil should not replace prescribed medication or professional treatment. Discuss persistent pain and any proposed changes to your treatment with a healthcare professional.
