Wound Healing and CBD: What the Research Shows

A child who falls and scrapes a knee, an adult who cuts a finger in the kitchen... Small wounds happen to all of us. In recent years, CBD creams and ointments have appeared on shelves with "wound care" promises, so it is only natural to wonder whether they really work. In this article, we cover how wounds heal, why CBD is being studied for this, what the studies found, possible side effects, and when you should see a doctor. The general evidence on skin problems is on the skin conditions page of the CBD Guide.

How do small wounds heal?

A scrape (abrasion) is a shallow wound caused by skin rubbing against a rough surface; it is most common on the knees, elbows, hands and feet. Cuts are made by a sharp object and can be deeper.

According to the UK's National Health Service (NHS), most small cuts and scrapes can be cared for at home and start to heal within a few days. The basic steps are:

• Wash your hands; if it is bleeding, stop it by pressing with a clean cloth.
• Clean the wound with tap water, bottled water or a sterile wipe; wipe the skin around it with soapy water.
• Pat the wound dry and cover it with an adhesive bandage or a sterile dressing; keep the dressing clean and dry.

These steps help keep the wound from getting infected. How much a cream or ointment adds to healing depends on the product and the type of wound.

Why are people curious about CBD?

CBD (cannabidiol) is a compound found in the cannabis plant that does not make you high or cloud your thinking. The body's "endocannabinoid system" is also present in the skin, and researchers are studying how this system relates to inflammation, itching and repair in the skin. Animal experiments have reported findings that CBD sped up wound closure and reduced the bacterial load in mice (Niyangoda 2024). These results are interesting, but an effect seen in animals does not mean it will work the same way in people.

What does the research say?

A 2024 review that gathered studies on cannabis products and wound healing looked at 18 studies: 11 were animal studies and 7 were human studies. The human studies had 92 participants in total and ranged in size from 1 to 69 people; most were single case reports or small case series. The products used also varied widely: along with CBD-only products, there were mixtures containing THC and other plant compounds. The authors stress that better-quality research is needed before anything definite can be said (Niyangoda 2024).

The key human studies are:

• Epidermolysis bullosa (Chelliah 2018): In this rare disease, where the skin is injured very easily, the experiences of 3 patients who applied CBD oil to their skin on their own initiative were described. The patients reported that their wounds healed faster, fewer blisters formed and their pain eased; one was able to stop the opioid medicine they used as a painkiller. This is an observation; there is no comparison group, and the authors say controlled studies are needed.
• Pyoderma gangrenosum (Maida 2017): In this rare disease that causes painful wounds, an oil made from medical cannabis was applied to the wounds. Pain decreased in all three patients and their need for opioids fell. This study looked at pain, not wound healing.
• Venous leg ulcers (Maida 2021): In 14 patients with an average age of 76 whose ulcers had not healed despite compression therapy, cannabis-derived creams were applied along with the bandages; in 11 patients the wound closed in a median of 34 days. There was no comparison group, and the patients continued their compression therapy. For details, see our article on venous insufficiency and CBD.

A broader review of skin conditions looked at 11 controlled studies and 6 other studies, most of them using cannabis products applied to the skin. It found a small reduction in itching; there was no clear difference in dryness, redness or quality of life. Most of the products studied contained other substances, not just CBD (Sermsaksasithorn 2025).

In short, there is currently no controlled human study showing that CBD applied to the skin speeds healing or prevents infection in everyday scrapes and cuts. The small studies on rare, hard-to-heal wounds are a starting point for future research.

Possible side effects and drug interactions

Products applied to the skin usually cause fewer side effects than those taken by mouth, but it is not accurate to say they have "no side effects."

• Skin reactions: The carrier oils, fragrances and other ingredients in creams can cause irritation or allergy in some people. Cases of rash have also been reported in people taking CBD by mouth (Souza 2022).
• Passing into the blood: In a study of five different CBD products applied to intact skin, CBD from three of the products passed into the blood. None of the urine tests came back positive; but unexpectedly, THC above the workplace testing cutoff was measured in the saliva of 9 participants (Zamarripa 2024). We could not find a study measuring how much passes into the blood through an open wound.
• Contents and claims: In most of the cosmetics and other CBD products sold in the US, the amount of CBD did not match the label; 40% of the products carried treatment claims such as "relieves pain" (Dowd 2025). You can find tips on reading labels on our label-reading page.

If you take CBD by mouth, you can read about drug interactions on our drug interactions page. The safety of CBD products applied to the skin has not been studied enough in children or during pregnancy and breastfeeding.

How was it used in studies?

In the wound studies, products were applied to the skin; in the venous leg ulcer study, the creams were applied to the wound and the skin around it every two days when the bandages were changed. Most studies did not report the amount of CBD or the other ingredients in the product in detail. There is no established CBD amount or application frequency for wounds; this information is not a personal recommendation.

If you are thinking about using CBD

It is only natural to want your wound to heal faster. According to the NHS, you should go to a healthcare facility without waiting if:

• There is soil, pus or dirt in the wound and it still looks dirty after cleaning,
• You were bitten by a person, or by a stray or wild animal,
• The wound is swelling, turning red, getting more and more painful or leaking pus,
• The cut is larger than about 5 cm or very deep,
• You feel generally unwell or have a fever,
• The bleeding will not stop, or there is loss of feeling around the wound.

If you have diabetes, circulation problems or a wound that has not healed for a long time, talk to your doctor before trying any cream. In Turkey, cannabis-derived products, including CBD, may be sold only in pharmacies (Law No. 7557, regulation of January 31, 2026). Those classed as medicines or health products are dispensed with a prescription; no prescription requirement is stated for supplement products with a THC content of no more than 0.3%. As of October 2026, there is no approved (licensed) CBD medicine in Turkey. For details, see our regulations page.

Conclusion

The role of CBD in wound healing is still being studied: animal experiments and a few small studies in rare wound diseases are interesting, but no controlled study shows that it works for everyday scrapes and cuts. Most small wounds heal with cleaning and a dressing; for a wound that is not healing or looks infected, the best step is to have a healthcare professional look at it.
