Loban Benefits and Side Effects: Smoke, Mosquitoes and Lungs
Loban (frankincense or benzoin resin) smells beautiful and carries real meaning in many homes, but its smoke is still smoke: it irritates lungs, can set off asthma, and should never fill a room with a baby in it. You can keep the fragrance and the tradition with a smaller piece, an open window and a few safety habits, and this guide explains how, plus the honest answer on mosquitoes.
Before you light it
- Two resins, one name: “loban” in Pakistan and India is usually benzoin (from Styrax trees); Arabic “luban” and kundur are frankincense (from Boswellia trees)
- Main risk: fine smoke particles, plus carbon monoxide if you burn it on charcoal in a closed room
- Keep away from: babies, anyone with asthma or COPD, pregnant women in a closed room
- Mosquitoes: thick smoke may keep a few away for minutes; it won’t protect you from dengue or malaria
- Eating it: better not

What is loban, and which kind do you have?
Both are tree resins, the sticky sap a tree releases when its bark is cut, dried into lumps. They look alike in a jar, and shops use the names loosely, so here’s the quick way to tell them apart.
| Benzoin (common “loban”) | Frankincense (luban, kundur) | |
|---|---|---|
| Tree | Styrax, from Southeast Asia | Boswellia, from Oman, Somalia, Yemen, India |
| Look | reddish brown lumps with milky white streaks, often sticky | pale yellow to greenish tears, dusty, harder |
| Smell when burnt | sweet, vanilla-like, warm | fresh, piney, lemony |
| Also sold as | sambrani, loban sticks, dhoop cones | “Omani luban”, kundur |
Many cheap “loban” cones and sticks contain mostly sawdust, charcoal powder, perfume and glue, with very little real resin, and those tend to make heavier, harsher smoke.
Why do families burn loban?
What people say
People say loban cleans the air, kills germs, chases away mosquitoes and insects, removes bad energy and nazar (the evil eye), and helps sleep.
What tradition says
Resin smoke has been used for fragrance and in worship across the Middle East and South Asia for thousands of years. In many Muslim homes loban is burnt after cleaning on Thursday evening or Friday, at a milad, or alongside recitation for protection and ruqyah, and in Hindu homes as dhoop at prayer time. These are personal and religious practices, and they deserve respect. Many scholars point out that the recitation, not the smoke, is the heart of ruqyah, so if smoke is a problem for someone in your home, ask your own scholar how to keep the practice without it.
Our honest take Depends
As fragrance, in a small amount with good airflow, loban is a pleasant habit for most healthy adults. As an air cleaner it’s the opposite: burning anything adds fine particles (PM2.5, specks small enough to reach deep into the lungs) to indoor air, and a room full of incense smoke can have far more of them than a busy road outside. Some resin smoke does have mild antimicrobial activity in lab tests, but you’d need to breathe the smoke for that to matter, which defeats the point. Our indoor air pollution guide covers the bigger picture.
Is loban smoke bad for asthma and babies?
Yes, it can be. Smoke is one of the most common asthma triggers, and children’s airways are smaller and more easily irritated.
- Babies: don’t burn loban in the room a baby sleeps or spends time in. Smoke exposure is linked to more chest infections, wheeze and ear infections in small children, and is a risk factor for sudden infant death.
- Asthma and COPD: even a little smoke can bring on coughing, tightness or a full attack. Our dama (asthma) home care guide explains other common triggers.
- Pregnancy: avoid sitting in a smoky room; open windows and step out while it burns.
- Elderly people and anyone with heart disease: they feel the effects of fine particles more.
The charcoal problem: carbon monoxide
Loban is often burnt on a glowing piece of charcoal in a small metal pot. Charcoal gives off carbon monoxide (CO), a gas you can’t see or smell, and in a closed room, especially in winter with the windows shut, it can build up enough to cause headache, dizziness, sleepiness, vomiting and confusion, and it can kill. Every winter people die in South Asia from charcoal angeethis in closed rooms.
If anyone feels headachy, dizzy or sick while loban or charcoal is burning, get everyone into fresh air at once, open doors and windows, and seek urgent medical help if symptoms don’t clear quickly or anyone is drowsy, confused or collapses.
Never fall asleep in a closed room with a burning coal.
How to burn loban more safely
- Use a pea-sized piece of resin, about 0.5 to 1 g. A small piece gives plenty of fragrance; a handful just makes smoke.
- Choose an electric resin warmer or a heat-proof dish on a tile, if you can. If you use charcoal, use one small disc, never a bed of coals.
- Open at least one window and the door before lighting, and keep the room aired for 10 to 15 minutes afterwards.
- Carry it through the house, then put it out on a stone or metal surface, out of reach of children, pets, curtains and bedding. Let it burn for 5 to 10 minutes, not hours.
- Kill the coal fully with sand or a little water before you leave the room or go to sleep, and empty the pot only when it’s cold.
Does loban smoke keep mosquitoes away?
Don’t rely on it Heavy smoke of any kind may make a few mosquitoes keep their distance while it’s thick, but the effect fades as the smoke thins and mosquitoes return within minutes. To keep smoke thick enough to matter, you’d need to fill the room in a way that’s bad for your lungs. For dengue and malaria seasons, nets, screens, removing standing water and a registered repellent work far better, as our mosquito repellent guide explains.
Myth: loban smoke kills viruses in the house
It doesn’t make a home safer from flu, COVID or other infections. Fresh air, open windows and cleaning surfaces do more, without any smoke at all.
Myth: real loban doesn’t produce harmful smoke
Pure resin burns cleaner than a cheap sawdust cone, but any burning makes fine particles and gases. Natural doesn’t mean smoke-free.
Can you eat loban?
Better not. Benzoin is not a food. In Oman and Yemen some people chew small tears of food-grade frankincense or soak them in water as a tradition, but loose resin from a pansar shop is meant for burning, may carry dust and other resins, and has no quality control for eating. Frankincense in herbal medicine is a separate matter for a qualified practitioner. Keep resin away from children: lumps can be a choking hazard, and if a child swallows loban or a cone, call your doctor or poison advice for guidance.
Did you know?
Frankincense was traded on caravan routes across Arabia for thousands of years, and Oman’s frankincense trees and old trading sites are a UNESCO World Heritage Site called the Land of Frankincense. Benzoin, the sweeter one, is also the base of “benzoin tincture”, once a standard item in pharmacies.
Skip loban entirely in a home with a newborn, someone with asthma or COPD, or a person on oxygen (oxygen and an open flame or coal can catch fire). Stop burning it if anyone coughs, wheezes or gets a headache. Get urgent help for wheeze that doesn’t settle with the usual inhaler, lips turning blue, struggling to speak, or symptoms of carbon monoxide such as headache, dizziness, vomiting or confusion. Treat a burn from a coal under cool running water for about 20 minutes, never butter, toothpaste or ice.
Loban questions, answered honestly
Is loban smoke harmful?
In small amounts with open windows it’s a minor exposure for most healthy adults. Heavy or daily smoke in a closed room raises fine particles indoors and can irritate the lungs, eyes and throat. It’s a real problem for babies and people with asthma.
What is loban in English?
In Pakistan and India loban usually means benzoin resin from Styrax trees. Arabic luban and the Urdu kundur are frankincense, a resin from Boswellia trees. Shops often use the names loosely.
Can I burn loban in a room with a baby?
No. Babies’ lungs are sensitive, and smoke exposure is linked to chest infections and is a risk factor for sudden infant death. Burn it in another room with the windows open and air it out before the baby comes back.
Does loban keep mosquitoes away?
Only briefly, and only while the smoke is thick. It won’t protect you from dengue or malaria. Use nets, screens, a registered repellent and remove standing water.
Is it safe to burn loban for asthma patients?
It’s best avoided. Smoke is a common asthma trigger, and even a small amount can set off coughing or wheeze. If it’s part of a religious practice, ask your scholar about doing it without smoke.
Can I burn loban on charcoal indoors?
Only briefly, with windows and doors open, using one small coal, and never while sleeping. Charcoal makes carbon monoxide, which can poison and kill in a closed room.
Is loban good for nazar?
Burning loban for protection is a cultural and religious tradition, and its meaning is for your faith and your scholar, not health science. From a health side, keep the amount small and the room ventilated.
Can you eat loban?
Better not. Benzoin is not edible, and resin sold for burning isn’t cleaned or graded for food. Food-grade frankincense chewing is a Gulf tradition, but it isn’t something we’d suggest at home.
What is the difference between loban and sambrani?
Sambrani is the South Indian name for benzoin, the same resin usually called loban in the north. Sambrani cups and cones often mix resin with charcoal and perfume.
Is loban smoke good for colds?
No. Smoke irritates an already sore nose and throat. Steam from a bowl of hot water, rest and fluids are kinder, and a fever lasting more than 3 days needs a doctor.
How to tell real loban from fake?
Real benzoin is reddish brown with white streaks and smells of vanilla when warmed. Frankincense is pale and smells piney. Cones that are mostly black powder and perfume are not pure resin.
Can loban cause headaches?
Yes, strong smoke and fragrance can trigger headaches in some people. A headache with dizziness or sickness while charcoal is burning could be carbon monoxide, so get into fresh air at once.
