With its sharp, lemony scent and natural insect-repelling power, citronella oil has earned a place in gardens, homes, and spa rituals across the world. Derived from lemongrass and long celebrated for both practical and aromatic reasons, this essential oil offers a unique blend of history, utility, and environmental integrity.
Citronella oil is a volatile essential oil obtained from the steam distillation of lemongrass, primarily Cymbopogon nardus and Cymbopogon winterianus. These aromatic grasses are native to Southeast Asia, but are now cultivated in India, Sri Lanka, Indonesia, Madagascar, and even some parts of South America and Africa.
The oil has a strong, fresh, lemony fragrance that makes it popular in perfumes, soaps, and candles — but it’s most famous for repelling mosquitoes and insects.
Citronella is best known for its mosquito-repelling properties. Unlike synthetic chemicals like DEET, citronella works by masking the scents that mosquitoes are drawn to - It’s effective in outdoor sprays, candles, and roll-ons.
Citronella oil has mild antiseptic and antifungal properties, making it useful for treating small cuts, minor infections, and fungal issues like athlete’s foot. It is often added to soaps and lotions for both fragrance and function.
Because of its strong citrus aroma, citronella acts as a natural deodoriser and air freshener. It neutralises unpleasant odours, especially in bathrooms and kitchens, and it’s often used in natural household cleaning sprays.
Like many citrus-based oils, citronella is said to have mood-lifting properties. Aromatherapists sometimes use it to reduce feelings of anxiety and fatigue.
In diluted form, citronella oil may help regulate oily skin, reduce pore size, and refresh tired or irritated skin. It’s commonly added to natural bar soaps, shampoos, and massage oils.
While citronella oil is considered safe when used correctly, there are some important caveats to know:
Skin Sensitivity: Like all essential oils, citronella must be diluted before applying to skin. Undiluted use may cause irritation or allergic reactions in sensitive individuals.
Pregnancy Use: Pregnant or nursing women should consult a healthcare professional before using essential oils, including citronella.
One of the most appealing things about citronella oil is that it’s relatively sustainable:
The Cymbopogon grasses grow quickly and are renewable.
Steam distillation is an energy-efficient extraction method.
The oil breaks down easily in the environment — no chemical residue, no water pollution.
However, as demand grows globally, it's important to look for ethically sourced citronella oil, ideally organic and Fair Trade certified. Overharvesting and monocropping can lead to soil degradation if not managed well.
Look for:
✅ Certified organic labels
✅ Small-scale or co-operative producers
✅ Sustainable packaging (glass bottles, recyclable materials)
Ancient Use: In Asia, citronella has been used for centuries in traditional medicine — as a fever reducer, insect repellent, and massage oil.
Colonial Trade: By the 19th century, citronella was being exported across Europe as a base for perfumes and as an insect repellent in tropical colonies.
WWII Era: The U.S. Army used citronella candles and sprays to protect troops in tropical areas, helping boost its popularity.
Modern Day: Citronella has become a staple in natural personal care and home cleaning products, especially with the rise in eco-conscious consumerism.
1. Gardeners and Campers, Golfers & Fishermen
If you enjoy time outdoors but dread bites and midges, citronella products (especially candles and sprays) are a must-have. Use citronella as a natural shield against flying pests.
2. Eco-conscious households
Looking for a multipurpose product that’s safe, natural, and environmentally friendly? Citronella oil can replace synthetic air fresheners, insect sprays, and chemical cleaners.
3. Skincare Enthusiasts
Those with oily or acne-prone skin may benefit from citronella-infused soaps and facial cleansers — particularly when combined with olive oil or glycerin bases.
4. Lovers of Natural Fragrance
Citronella is ideal for those who appreciate fresh, citrusy aromas without synthetic chemicals. It's a beautiful addition to diffusers and candles.
5. Zero-waste and sustainable living advocates
Since citronella oil is plant-derived and biodegradable, it’s ideal for refillable products, solid bars, and plastic-free packaging lovers.
When purchasing citronella oil or products containing it, consider:
Purity: Is it 100% citronella essential oil?
Origin: Where was it sourced, and under what conditions?
Application: Is it for skin, air, or surfaces? Always follow safety instructions.
Combination: Some products blend citronella with lavender, eucalyptus, or lemongrass for extra potency and scent complexity.
Citronella oil is one of nature’s most versatile and effective essential oils — offering a refreshing fragrance, powerful insect-repelling properties, and gentle skincare benefits, all with strong sustainability credentials. Whether you’re heading outdoors, cleaning your kitchen, or seeking an alternative to synthetic ingredients, citronella has a place in your daily rituals.
