That sharp-smelling white block in old medicine cabinets has more science behind it than you might expect.
If you have ever rubbed a mentholated balm on a sore shoulder or breathed in a vapor rub during a cold, you already know camphor. This waxy, translucent solid comes from the Cinnamomum camphora tree and has been a staple of pain ointments for centuries. Its cooling feel and quick absorption also explain why it keeps turning up in skin and hair products.
Research suggests camphor carries anti-inflammatory, antibacterial, and antifungal activity, along with calming effects that may help with stress and sleep (2). Here is what it may do for you, and just as important, how to handle it safely.
Key Takeaways
– Camphor is a strongly scented, flammable solid extracted from the camphor tree, traditionally used in balms and ointments.
– It may soothe itchy or irritated skin, calm acne and eczema flare-ups, and ease muscle pain.
– Anecdotal evidence links camphor oil to stronger hair roots and better hair growth, though research here is thin.
– Camphor should never be swallowed, applied to broken skin, or handled by children. Over-inhaling it can cause vomiting and poisoning.
– Adults can generally use diluted camphor two to three times a day, ideally after a patch test.
What Exactly Is Camphor?
Camphor oil is distilled with steam from the stems of camphor trees, and only trees around 50 years old produce the active component. Commercially, it is often manufactured from turpentine.
Chemically, it is a terpene containing compounds such as pinene and 1,8-cineole. These give it a long list of studied properties, including antioxidant, antispasmodic, and sedative effects alongside its antimicrobial ones (2).
The Different Types of Camphor
Not all camphor is the same, and the type matters for skin use.
White camphor is the refined form made from the wood. It is the one found in most medicines and aromatherapy products, and it is generally safe when diluted in a carrier oil.
Yellow camphor comes from the leaves and bark and smells stronger. It appears in traditional medicine and some beauty products; sensitive skin calls for a patch test first.
Brown and black camphor are less refined, keep more of the tree’s raw compounds, and are more likely to irritate skin.
Red camphor, made from the bark, is the least common and is used mainly in traditional remedies.
How Camphor May Help Your Skin
SaveThis is where camphor has the most going for it. Its antibacterial and antifungal nature may relieve itching and general irritation (2), and it shows up in ointments for a range of fungal and bacterial skin infections.
An animal study found camphor to be a potent wound-healing agent, apparently by boosting collagen and elastin production in skin cells, which is also why it appears in some anti-wrinkle cosmetics (3). Human research on this is still limited, so treat it as promising rather than proven.
A few more specific uses stand out:
Acne. Compounds in camphor such as 1,8-cineole and camphene have antibacterial activity that may help with breakouts, along with the swelling around inflamed follicles (6).
Eczema. Camphor is used to control the itching and inflammation of flare-ups (7).
Burns. In a rat study, an ointment combining camphor, sesame oil, and honey shortened burn healing time (5). A small amount dissolved in water, applied daily, is a traditional approach to fading burn scars.
Nail fungus. Its antiseptic and antifungal properties make camphor paste a useful option against toenail fungus (8).
Heat rash. Camphor dissolved in water is a common home remedy for rashes from heat and sweat, thanks to its anti-inflammatory compounds (2).
Cracked heels deserve an honest caveat. Soaking your feet in camphor water, scrubbing, and moisturizing afterward is a popular routine, but the evidence here is purely anecdotal.
Can Camphor Really Help Your Hair?
SaveThe claims are enthusiastic; the research is not there yet. Anecdotally, camphor oil is said to strengthen hair roots, especially when mixed with egg or yogurt to add nutrients. Combined with certain essential oils, it is also believed to encourage hair growth. If you want to try it, a scalp treatment once or twice a week is a low-risk experiment, provided the oil is properly diluted and your scalp skin is intact.
Everyday Health Uses
Beyond skin and hair, camphor has a long resume. It may help relieve muscle pain, and a study from Hamdard University found that a spray blending camphor with menthol, eucalyptus, and clove had genuine analgesic and anti-inflammatory effects (4). It is also traditionally used for stress relief, better sleep, improved circulation, and easing colds and coughs (2). A simple homemade chest rub mixes camphor with olive oil and beeswax.
Side Effects and Safety Rules
This part is not optional. Camphor is flammable and can be toxic when misused, so a few rules apply:
Never swallow it, and never apply it to broken skin. It can be absorbed into the body and cause poisoning.
Keep it away from your eyes, and out of reach of children entirely. Only adults should handle it.
Breathing in too much can trigger vomiting and poisoning.
Do a patch test before using it on skin, and stop if a condition worsens rather than improves.
Used sensibly, diluted camphor two to three times daily is generally considered fine for adults.
Frequently Asked Questions
How often can I use camphor?
Adults can typically use diluted camphor on skin or hair two to three times per day. Start with a patch test, and back off if you notice redness or stinging.
Is it safe to eat camphor?
No. Camphor should never be ingested in any form or amount. Swallowing it can cause serious poisoning.
Which type of camphor is best for skin?
White camphor is the most refined and the most common in skincare, but even this type should be mixed with a carrier oil rather than applied directly, especially on sensitive skin.
The Bottom Line
Camphor earns its place in the medicine cabinet. The strongest evidence supports it for pain relief and for skin complaints like itching, acne, and minor infections, while the hair-growth and cracked-heel claims lean mostly on tradition. Respect the safety rules, dilute it properly, keep it off broken skin, and never ingest it, and this old-school remedy can still be a useful one.
