Key Takeaways
You might remember that as a child, our grandmothers had a solution to all of our problems. Besides chemical medication, they trusted organic remedies. Camphor is one of those substances grandmothers always used and modern science is proving they were right.
The camphor benefits had also been documented in traditional Ayurvedic medicine, traditional Chinese medicine and European folk medicine. And for more than 3,000 years, it has been tested pharmacologically. Today, the WHO reports that almost 80% of the world's population is still using traditional medicine. Camphor is one of the few traditional medicines that is mentioned in Ayurveda, TCM, Unani medicine and European folk medicine at the same time.
In this guide, I will tell you the chemistry behind camphor's action and effects. 7 scientifically proven benefits of using camphor. How to safely use camphor on feet and the Imperial Feet containing camphor in foot products.
What Is Camphor? Origin, Chemistry and How It Works on Skin
The Camphor Laurel Cinnamomum camphora (Linn.) J.Presl. is a tree of East Asia (China, Japan, Taiwan), which can grow up to 30 meters tall and can survive for centuries. The INCI name used in cosmetics is simply Camphor.
It is a waxy, white or clear solid at room temperature with a powerful aromatic odour. Very volatile and absorbs quickly through the skin when touched. Camphor is naturally extracted through steam-distillation of its wood, bark and leaves. Only the most refined fraction of camphor, which is white (the most refined), is used in therapeutic products.
Understanding how it works on skin is based on receptor chemistry. Camphor is an agonist for both warm and cold receptors, the TRPV1 and TRPM8 receptors. In simple words, it plays a trick on your nervous system so it feels both cold and hot and turns off pain signals. Here is the counter-irritant effect that everyone is familiar with, the warming then cooling effect.
The rubefacient action is the next. Camphor dilates superficial capillaries and increases the blood flow in the area, which causes the skin to warm up. The metabolic activity increases in the tissues below it.
Camphor side effects are also important to keep in mind that before using its products, they should be used topically and with diluted concentrations (less than 11%) according to the EU Cosmetics Regulation. Never ingest it. Do not use cuts or abrasions. Do not use on or near infants.
For recurring fungal or odour problems, treat both the feet and the shoe environment to help reduce the risk of reinfection.Pro tip
7 Science-Backed Camphor Benefits for Foot Care and Skin Health
Camphor has been used in traditional as well as modern medicines for a long time. It is because it has proven its worth in multiple areas. Imperial Feet has also been using camphor for athlete’s foot treatment and other foot issues since 2001.
Benefit 1: Camphor Antifungal Properties Against Toenail and Foot Fungus
Camphor disrupts fungal cell membrane integrity and inhibits ergosterol biosynthesis just like pharmaceutical antifungals. It also inhibits the growth of fungus spores.
According to one study published in the Separations Journal in 2023, the methanolic extract of C. camphora was found to inhibit Fusarium oxysporum by 60% at a concentration of 4000µg/mL. Previous studies have been carried out to confirm the antifungal effect of camphor oil against a variety of fungal species. Learn more about different types of foot fungus and treatment.
A 2011 clinical trial showed improvement in nail fungus in 15 of 18 people after 48 weeks using a nail fungus formula that contains camphor as well as menthol and eucalyptus. First randomized controlled trial (RCT) of camphor oil for toenail fungus.
Most antifungal shoe spray with camphor kills Trichophyton rubrum spores inside shoes. It is the source of reinfection that undermines most antifungal nail treatments; that's what Imperial Feet products accomplish.
Benefit 2: Natural Pain Relief and Muscle Cramp Reduction
Camphor pain relief action is known to have two pathways.
-
First: Counter-irritation, which is the activation of TRPV1 and/or TRPM8 receptors which create a warming/cooling sensation that overrides deeper pain signals at the neural level.
-
Second: The anti-inflammatory and anti-pain action of camphor is due to blocking the cyclooxygenase-2 pathway, the same mechanism that is responsible for the anti-inflammatory and anti-pain properties of NSAIDs.
As per research done by Nikura (2016) camphor oil reduced the swelling of the lymph nodes and helped to alleviate back pain. It is effective against foot pain, including muscle cramps, aching feet after extended periods of standing, pain of plantar fasciitis and stiffness in the toe joints due to arthritis.
This is no placebo effect. Camphor topical application, at safe concentrations, has a well-established mechanism of action with neurological effects that are effective in reducing pain as compared to over-the-counter analgesics without systemic absorption.
Benefit 3: Camphor Antibacterial Properties for Foot Skin Infections
In 2025, PMC conducted a study on C. camphora borneol chemotype, which found that it has antibacterial properties against S. aureus, E. coli, and other pathogenic bacteria. The mechanism is that the terpene compounds present in camphor like eucalyptol and limonene. They interfere with the bacterial cell membrane and inhibit the activity of bacterial enzymes.
About foot odour. The main bacteria involved in converting sweat into volatile, smelly compounds are Brevibacterium and Staphylococcus epidermidis. The antibacterial properties of camphor against these species are the reason why it is used in antibacterial shoe spray for foot odour.
The term secondary bacterial infection is used in the context of an athlete's foot. It refers to the frequent secondary bacterial infections that often occur following fungal infections, especially in cases of ulceration or severe maceration. The antibacterial and antifungal properties are effective at treating both types of infections. A single ingredient, two solutions.
Benefit 4: Anti-Inflammatory Relief for Swollen and Tired Feet
Camphor also inhibits NF-κB pathway, which is a master regulator of pro-inflammatory gene expression. It includes cytokines such as tumor necrosis factor (TNF-α), interleukin (IL-1β), and IL-6. A 2020 PMC study of C. camphora essential oil has been proven to have significant anti-inflammatory activity. In 2019, an NCBI study showed that C. camphora leaf extract reduced IgE levels, inflammation of the lymph nodes and swelling of the skin in allergic inflammatory models.
The anti-inflammatory effects of camphor help with swollen ankles. It happens after long-standing, inflamed tissue in the bunions, tired toes after exercise and inflammation of the joints of the toes caused by arthritis. The mechanical circulatory effect and the reduction of cytokines responsible for inflammation are obtained by the simultaneous application of camphor.
Benefit 5: Camphor Oil Benefits for Skin-Strengthening and Wound-Healing
Camphor stimulates the proliferation of the cells of the skin (keratinocytes) and stimulates the production of collagen. It contains antioxidant terpenes, linalool and borneol, which help to prevent oxidation damage to skin cells, reduce visible skin aging.
Mild keratolytic activity stimulates new, healthy skin under hyperkeratotic skin (calluses, thickened areas on the heels). Camphor has been shown to promote wound healing in several animals due to its pro-angiogenic and pro-fibroblast effects.
Caution: Camphor is able to cause systemic toxicity and easily passes through damaged skin barriers; never apply this directly to open wounds or broken skin. It is really a wound-healing adjunct and not a wound itself.
Benefit 6: Deodorising and Odour-Neutralising Effects on Feet
Molecular binding allows camphor's potent volatile aromatic chemicals to directly neutralize the molecules of odor and kill the germs responsible for it. It is a double-action solution.
Imperial Feet's Shoe & Sock Spray contains two odor-trapping compounds, camphor and Zinc Ricinoleate, which provide chemically-bound neutralisation. Camphor is highly volatile and penetrates the fibre of the fabric as well as the skin of the foot, creating an immediate and lasting effect for 12 hours.
Benefit 7: Improving Local Circulation and Warming Cold Feet
Camphor is a rubefacient that directly causes histamine release and activates TRPV1 receptors to cause local vasodilatation of superficial capillaries. This warming effect can be measured, and it improves the tissue oxygenation of the area without causing any systemic reactions that oral vasodilators do.
It is especially useful for,
-
Elderly patients who have weak peripheral circulation
-
Diabetics with mild circulation problems (topical only, avoid broken skin)
-
In the workplace people are exposed to cold conditions whose feet become stiff and sore from extended periods of cold.
Massage made with upward strokes and camphor action enhances the vasodilation effect.
How to Use Camphor Specifically for Foot Care: Step-by-Step
Use Case 1 — Shoe Disinfection (Re-infection Prevention):
-
After use, remove your shoes.
-
Inside each shoe (especially toe box) apply 2-3 sprays of Imperial feet anti-fungal shoe disinfectant spray.
-
Socks can be sprayed either before or after washing.
-
If shoes are damp, let them dry thoroughly before next use: the camphor vapour will penetrate fibres and neutralise spores.
-
Repeat 2-3 times per week for maintenance and repeat after each wear during an active infection.
Use Case 2 — Pain Relief and Muscle Soreness:
-
Apply a balm or cream containing camphor, at a safe concentration (NEVER apply undiluted camphor oil).
-
Apply a small amount on the painful calf, heel or arch.
-
Rubefacient effect will intensify as you do circular motions, massage for 60-90 seconds.
-
Cover with a cotton sock to help keep warm and penetrate further.
-
Repeat 3-4 times a day. Do not use it on damaged skin or in the eyes.
Use Case 3 — Foot Odour (Daily Deodorising):
-
Wash and dry your feet thoroughly, then apply a foot deodorant containing camphor to the soles and between your toes.
-
Allow to dry completely before putting on socks.
-
Use internally in shoes also; the camphor vapour stops bacteria regrowing during the day.
Use with the athlete's foot solution for the skin infection when there are both odour and fungal problems.

Camphor in Imperial Feet Products: Science Formulated for Your Feet
Camphor was not included as a folk element for the sake of tradition. It has been scientifically tested, having a certain pharmacological profile and has been used in Imperial Feet compositions.
Never apply undiluted camphor oil directly to your feet; use a professionally formulated product at a safe concentration instead.Important
The Anti-Fungal Shoe Disinfectant Spray has an antifungal action (anti-dermatophyte action, destroying dermatophyte spores in shoe environment) and deodorising action (anti-odour bacteria action, binding the volatile odour compounds). Two additional mechanisms of action that target both fungal and bacterial infections at the same time.
This is important because approximately 80% of fungal infections are recurring as a result of contaminated shoes. The shoe's importance to treatment is due to the fact that Shoe Spray contains camphor. For the full antifungal foot treatment products, explore the whole treatment plan.
Use the Camphor Shoe Spray with Nail Mycosis Solution especially for nail fungus. Both the Nail Mycosis Solution and camphor are for treating the shoe environment. It has been entrusted by podiatrists and pedicurists in 20+ countries since 2001.

Frequently Asked Questions About Camphor for Feet
Can You Apply Camphor Oil Directly to Feet Without Diluting It First?
No. Camphor oil is often found with over 50% camphor, far exceeding the EU safe limit for topical use of only 11%. Undiluted camphor is toxic and may irritate the skin or cause systemic effects if absorbed through skin defects. Apply professionally formulated cosmetic products containing camphor that have been pre-diluted to safe cosmetic levels. In antifungal shoe spray, the amount of camphor is safe and regulated.
Is Camphor Effective for Treating Toenail Fungus at Home?
The main cause of toenail fungus, Trichophyton species, has been shown to be susceptible to the antifungal effects of camphor. In a clinical study from 2011, Vicks VapoRub, a camphor-containing product, was shown to be effective in 15 of 18 patients with nail fungus after 48 weeks. Camphor alone may not penetrate deeply enough into the nail plate to treat onychomycosis. To improve nail penetration, use a specially formulated product. See tea tree oil for fungal nails for the science behind nail penetration.
What Is the Difference Between Natural and Synthetic Camphor?
Natural camphor is obtained from Cinnamomum camphora by steam distillation and has a complete terpene spectrum, including eucalyptol, limonene, borneol, linalool, and other compounds that contribute to its broad range of activity. Synthetic camphor is the pure camphor molecule without the terpene matrix. Both can be used safely at appropriate concentrations. Natural camphor has broader-spectrum activity, which is why it is preferred in professional therapeutic formulas.
Can Camphor Help With Foot Odour and What Is the Mechanism?
Yes. Camphor can help address foot odour in two ways. It can inhibit bacteria such as Brevibacterium and Staphylococcus epidermidis that contribute to odorous compounds in sweat, while its aromatic volatile molecules can help neutralise existing odours. In Imperial Feet's Shoe Spray, camphor is combined with the active ingredient Zinc Ricinoleate and the plant compound Farnesol. These complementary mechanisms help neutralise odour and provide up to 12 hours of freshness.
Is Camphor Safe for Diabetics to Use on Their Feet Regularly?
Topical use of camphor-containing products with less than 11% camphor is generally acceptable for diabetic feet when used as directed. However, never apply a camphor product to a wound, ulcer, or cracked skin. Skin breaks can increase transdermal absorption and may increase the risk of adverse effects. Unlike some shoe and sock sprays, Imperial Feet's Shoe Spray is applied inside shoes rather than directly to the skin, making this a safer way to use camphor for many people with diabetes.
