Zam-Buk is the dark green herbal ointment in a small tin that has been in South African homes for well over a century. It is used for minor cuts, grazes, bites, chapped skin, muscle rub and a great many other things. It is a traditional remedy rather than a registered medicine, and its reputation runs somewhat ahead of the evidence.
What is Zambuk?
No product called Zam-Buk appears on the South African Medicine Price Registry, which lists SAHPRA-registered medicines. Zam-Buk is sold as a traditional or complementary product, which is why it is absent — not because there is anything irregular about it.
It is one of the most recognisable products in South Africa. First made in England in the early 1900s, it became so widely used at rugby and boxing matches that “Zambuk” entered South African English as a word for a first-aid attendant or St John’s volunteer.
What it contains — read your own tin, since formulations change — has traditionally been a paraffin and oil base carrying eucalyptus, camphor, thyme oil and colophony (pine resin), with chlorophyll giving the dark green colour.
Two mechanisms are doing most of the work, and both are real:
It is an occlusive barrier. The paraffin base seals the skin, keeping moisture in and dirt out. For chapped lips, cracked heels, dry hands and minor grazes, this is genuinely most of the benefit — the same reason plain petroleum jelly works.
It is a mild counter-irritant. Camphor and eucalyptus produce a cooling then warming sensation that distracts from underlying aching. It does not reach a muscle or joint underneath — the effect is on the skin’s nerve endings.
Camphor, eucalyptus and thymol also have mild antiseptic activity, which is a genuine but modest property.
What it does not do, despite generations of claims: draw out splinters or thorns, cure boils, treat infection, penetrate to joints, or heal anything faster than clean skin and a dressing would.
What is Zambuk commonly used for?
Traditionally applied to:
- Chapped lips, cracked heels and dry hands — where the barrier effect genuinely helps.
- Minor cuts, grazes and scratches, after cleaning.
- Insect bites and stings, to soothe itching.
- Sunburn and minor burns, though not on fresh or blistered burns.
- Muscle aches and stiffness, as a rub.
- Bruises.
- Nappy rash and chafing.
- Boils, pimples, splinters and thorns, traditionally to “draw” them out — which it does not do.
- Blocked nose, dabbed under the nostrils for the eucalyptus vapour.
Where it is a reasonable choice: dry, chapped, cracked skin, and soothing a bite or graze once cleaned. Cheap, keeps indefinitely, harmless on intact skin.
Where something else is better:
- A wound that needs cleaning — running water and mild soap do far more than any ointment. Rinsing dirt out of a graze prevents more infection than anything applied afterwards.
- An infected wound — spreading redness, pus, heat and swelling need an antiseptic or antibiotic and often a doctor, not a herbal ointment.
- A boil or abscess — a collection of pus needs drainage. Ointment does not draw it out, and delaying while trying makes it worse.
- A deep, gaping or dirty wound — cleaning, possibly closure, and a tetanus check.
- A splinter or thorn — remove it with clean tweezers, or have it removed.
How Zambuk fits into this medicine category
It is a traditional remedy rather than a registered medicine:
| Type | Examples | Notes |
|---|---|---|
| Traditional ointments | Zam-Buk, and similar herbal balms | Barrier plus counter-irritant; light regulation |
| Barrier preparations | Petroleum jelly, zinc and castor oil | Protect and seal; the main effect here |
| Antiseptics | Povidone-iodine, chlorhexidine, cetrimide | Actually reduce bacteria on a wound |
| Topical antibiotics | Mupirocin, fusidic acid | Prescription; for infected wounds |
| Topical steroids | Clomaderm | Inflammation, eczema |
| Antifungals | Canex V | Fungal skin infection |
| Topical NSAIDs | Diclofenac gel | Genuinely reach muscle and joint |
That last row is the honest comparison for aches. Zam-Buk produces a sensation on the skin; a diclofenac gel delivers an anti-inflammatory into the tissue beneath. For a strained muscle or an arthritic knee, the gel does something the balm does not.

What to check before using Zambuk
Do not use it on babies or very young children. Camphor and eucalyptus are genuinely dangerous in infants — applied near the face or nose they can cause breathing difficulty, and camphor swallowed by a small child can cause seizures. Keep the tin out of reach, and do not apply it under a baby’s nose or on the chest of an infant.
Also take care if you:
- Have asthma, where camphor and eucalyptus vapour can trigger wheezing.
- Have sensitive skin or eczema. Colophony (pine resin) is a well-recognised contact allergen, and fragrance ingredients commonly cause reactions.
- Are pregnant or breastfeeding — avoid applying it to the breast area.
- Have broken, weeping, burned or infected skin.
- Have epilepsy, given camphor’s effects if absorbed in quantity.
Practical points:
- Clean the skin first, with running water — this matters more than the ointment.
- Apply a thin layer to intact or lightly grazed skin.
- Keep it away from the eyes, inside the nose, and mucous membranes.
- Do not apply it to a fresh burn, deep wound, or blistered skin.
- Do not cover it with an airtight dressing, which increases absorption.
- Do not use it on large areas of skin.
- Never swallow it, and keep it away from children.
- Wash your hands afterwards.
Possible cautions and when to ask a pharmacist or doctor
The commonest problem is contact dermatitis — redness, itching, a rash or small blisters where it has been applied. This is usually a reaction to the fragrance or the colophony, and it settles on stopping.
Get emergency help for:
- A child who has swallowed Zam-Buk or any camphor-containing product, even a small amount and even if they seem well. Take the tin with you. Camphor causes seizures in children at surprisingly small doses.
- Difficulty breathing or wheezing after application, particularly in a child or someone with asthma.
- Swelling of the face, lips or tongue.
- A widespread rash with blistering or peeling.
- A rapidly spreading red, hot, painful area with fever.
See a doctor about the underlying problem if:
- Redness is spreading from a wound, particularly as a streak up a limb.
- A wound is increasingly painful, swollen, warm, or discharging pus.
- You develop a fever.
- The wound is deep, gaping, or will not stop bleeding.
- It was caused by an animal or human bite, something dirty or rusty, or a puncture.
- There is something still in it — glass, grit, a thorn.
- It is not healing after a week or two.
- You have diabetes, poor circulation, or a weakened immune system. Foot wounds in diabetes need professional assessment early, not home treatment.
- Your tetanus vaccination is out of date or you are unsure.
- You have a boil or abscess that is enlarging, painful or feverish.
A closing note. Zam-Buk has earned its place in South African cupboards, and for chapped skin and small grazes it is perfectly reasonable. What it should not be is a reason to delay — a spreading infection, an abscess, or a wound in a diabetic foot needs proper attention, and a tin of green ointment is not it.

Frequently asked questions
What is Zam-Buk used for? Chapped lips, cracked heels and dry hands, minor cuts and grazes, insect bites, and as a muscle rub. It is a traditional herbal ointment, not a registered medicine.
Does it draw out splinters or boils? No. That is a long-standing claim with nothing behind it. A splinter needs removing with clean tweezers; an abscess needs draining.
Does it reach my sore muscle? No. Camphor and eucalyptus create a cooling-then-warming sensation on the skin. A diclofenac gel genuinely delivers an anti-inflammatory into the tissue beneath.
Is it an antiseptic? Mildly. Camphor, eucalyptus and thymol have modest antiseptic activity — but rinsing a wound under running water does far more.
Can I use it on my baby? No. Camphor and eucalyptus are dangerous in infants — they can cause breathing difficulty applied near the face, and camphor swallowed causes seizures in small children.
Can I use it on a burn? Not on a fresh or blistered burn. Cool the burn under running water and get it assessed if it is more than very minor.
Why has my skin become itchy and red? Probably contact dermatitis from the fragrance or the colophony (pine resin), both recognised allergens. Stop using it.
Is it a registered medicine? No. It is sold as a traditional or complementary product, which is why it does not appear on the medicine price register.
