Isibabuli is the isiZulu word for sulphur — the yellow powder sold in pharmacies and traditional shops and used for generations in South Africa for skin complaints, scabies, ringworm and as a general cleansing remedy. Sulphur has genuine antiparasitic and antifungal properties, and it also has real limits worth understanding.
What is Isibabuli?
Isibabuli is sulphur — usually sold as sublimed sulphur (flowers of sulphur), a fine bright yellow powder, or as precipitated sulphur, a finer form used in ointments.
No product under this name appears on the South African Medicine Price Registry, which lists SAHPRA-registered medicines. Sulphur is sold as a raw material or traditional remedy, which is why it is absent — not because there is anything irregular about it.
Sulphur is one of the oldest treatments in medicine, used continuously since antiquity. Its effects on skin are genuine, with a proper mechanism behind them: on the skin it is slowly converted to hydrogen sulphide, producing several effects.
It is antiparasitic. Sulphur kills the scabies mite, and precipitated sulphur ointment remains a recognised scabies treatment — recommended by the WHO, and notably the treatment of choice for infants under two months and in pregnancy, where permethrin and ivermectin are not used.
It is antifungal and antibacterial, with modest activity against the fungi causing ringworm and against Cutibacterium acnes in acne.
It is keratolytic — it softens and loosens the outer layer of skin, which helps in seborrhoeic dermatitis, dandruff and acne.
Its limits are equally real. Sulphur is slower and less effective than modern antiparasitics and antifungals, smells strongly, stains, and irritates skin. Where permethrin or a modern antifungal is available, they generally work better and faster. Sulphur’s place is in infants, in pregnancy, where cost is an issue, and where it is the tradition.
What is Isibabuli commonly used for?
Where it genuinely works:
- Scabies — the intensely itchy burrowing mite infestation. A recognised treatment, and the preferred one in babies under two months and in pregnancy.
- Ringworm and other fungal skin infections, modestly.
- Acne, where sulphur appears in many commercial preparations.
- Seborrhoeic dermatitis and dandruff, in shampoos and creams.
- Rosacea, in sulphur preparations.
- Lice, traditionally.
Traditional uses without supporting evidence: taken internally as a cleansing remedy, “blood cleansing”, general undiagnosed rashes, burning as a fumigant, and ritual or protective use.
Two things need saying clearly.
Sulphur should not be swallowed. Taken internally it causes nausea, vomiting and diarrhoea, and in quantity is genuinely toxic — hydrogen sulphide is poisonous. Traditional preparations taken by mouth have caused serious harm, and there is no condition for which swallowing sulphur is an effective treatment. Its uses are on the skin.
Burning sulphur produces sulphur dioxide, which is a respiratory irritant and dangerous in an enclosed space — particularly for anyone with asthma, and for children.
Scabies deserves a specific note, being where isibabuli is most used and most often misapplied:
- Everyone in the household must be treated at the same time, whether or not they itch.
- Bedding, towels and clothing from the previous few days must be washed hot, or sealed in a bag for a week.
- The itch continues for two to four weeks after successful treatment — an allergic reaction to dead mites, not treatment failure. This is the commonest reason people repeat treatment unnecessarily.
- Apply to the whole body from the neck down, including between fingers and toes and under nails. In infants and the elderly, include the scalp and face.
Who commonly looks for Isibabuli and why
People with scabies, or treating a household through it — the commonest reason, and the one where sulphur genuinely earns its place. It is cheap, widely available, and the preferred option for babies and in pregnancy.
Parents of infants with scabies, where permethrin and ivermectin are not used under two months and sulphur ointment is the recommended treatment.
People with an itchy rash they have not had diagnosed, reaching for a familiar remedy. This is where it most often goes wrong — scabies, eczema, ringworm and allergic rashes all itch, need different treatments, and using the wrong one delays the right one.
People with acne or dandruff, where sulphur is a real if modest ingredient.
People using it culturally or traditionally. Those uses sit outside what evidence can speak to — but the safety points below still apply, particularly about swallowing it and burning it indoors.
People who cannot access or afford modern treatments. Sulphur is inexpensive and works.

Sulphur’s honest position: a real treatment with a long history, genuinely useful in specific situations — particularly infants and pregnancy — and generally outperformed by modern alternatives elsewhere.

What to check on the label before taking Isibabuli
- That it is intended for external use. Do not swallow sulphur.
- The form. Precipitated sulphur is finer and less irritating than sublimed for skin use.
- The concentration. Scabies preparations are typically 5 to 10 per cent.
- Whether it came from a pharmacy or an informal source — purity is a real concern with informally sold powders.
Do not use it on:
- Broken, weeping, blistered or badly inflamed skin.
- Large areas of an infant, without medical advice.
- The eyes, mouth or genital mucous membranes.
Safety, interactions and when to seek professional advice
Used on the skin as directed, sulphur is generally safe — which is precisely why it remains the option for babies and in pregnancy.
Common effects: skin irritation, dryness, redness, itching, burning and peeling, a strong smell, and staining of clothing, bedding and jewellery.
Speak to a pharmacist or doctor before use if you:
- Are treating an infant — sulphur is suitable but the concentration and application need guidance.
- Are pregnant or breastfeeding — it is the preferred scabies treatment, but confirm.
- Have eczema, psoriasis or very sensitive skin.
- Have kidney disease.
- Are treating widespread or crusted scabies, which needs medical management.
Get emergency help for:
- Anyone who has swallowed a significant amount of sulphur, particularly a child. Take the container.
- Difficulty breathing, coughing or wheezing after exposure to burning sulphur or sulphur fumes — get into fresh air immediately.
- Swelling of the face, lips or tongue.
- A widespread blistering or peeling rash.
Seek prompt advice for:
- Severe skin irritation where applied.
- Skin becoming infected — increasing redness, warmth, pus, or fever. Scratched scabies commonly becomes infected, and that needs antibiotics.
- A rash that is spreading or changing.
See a doctor rather than self-treating if:
- Itching persists beyond four weeks after treatment.
- Scabies keeps recurring — usually meaning household contacts were not all treated.
- The skin is crusted, thickened or widespread — crusted scabies is highly contagious and needs specialist treatment.
- You have diabetes, poor circulation or a weakened immune system.
- You are treating an infant and it is not settling.
- The rash has not been diagnosed. Scabies, eczema, ringworm and allergic rashes all itch and need different treatments — and using the wrong one delays the right one.

Frequently asked questions
What is isibabuli used for? It is the isiZulu word for sulphur, used on the skin for scabies, ringworm, acne, dandruff and general skin complaints.
Does it actually work? On the skin, yes. Sulphur genuinely kills the scabies mite and has modest antifungal and antibacterial activity. It is slower and less effective than modern treatments for most people, but it remains the preferred option for babies under two months and in pregnancy.
Can I swallow it? No. Swallowed sulphur causes nausea, vomiting and diarrhoea, and in quantity is toxic. Its effective uses are on the skin.
Can I burn it to cleanse a room? Burning sulphur produces sulphur dioxide, a respiratory irritant that is dangerous in an enclosed space — especially for anyone with asthma and for children.
Why does my itch continue after treatment? The itch of scabies lasts two to four weeks after successful treatment, because it is an allergic reaction to dead mites. That is not treatment failure.
Why does the scabies keep coming back? Almost always because the whole household was not treated at the same time, or bedding and clothing were not dealt with.
Is it safe for a baby? Sulphur is the preferred scabies treatment in infants under two months, but get guidance on the concentration and how to apply it.
Does it stain? Yes. Sulphur stains clothing, bedding and jewellery, and has a strong smell.
