Lemongrass Oil: 20 Benefits, Side Effects, Uses & How to Make

Lemongrass oil is one of those refreshing, citrusy, deeply aromatic oils that instantly lifts your mood the moment you open the bottle. Whether you’ve encountered it in a spa, an aromatherapy diffuser, herbal medicine, or even in a homemade bug repellent, you already know its energizing smell. But beyond the pleasant fragrance, lemongrass oil is also packed with healing properties. From easing inflammation to supporting digestion and skin health, it has quietly become one of the most popular essential oils around the world.

In this guide, we’ll walk through everything you need to know about lemongrass oil in daily life—its science-backed health benefits, side effects, how to use it, how much you should take, precautions, and even a simple DIY recipe to make your own at home.

What is Lemongrass Oil?

Lemongrass oil is an essential oil extracted from the fresh or partially dried leaves of the lemongrass plant (Cymbopogon citratus and Cymbopogon flexuosus). These long, aromatic grasses are native to Asia and Africa but are now cultivated worldwide because of their culinary and medicinal value.

The oil is typically extracted using steam distillation, which captures the powerful compounds present in the plant—especially citral, the main component responsible for its lemony smell and strong therapeutic potential.

Traditionally, lemongrass has been used in Ayurveda, Chinese medicine, and folk remedies to support digestion, relieve pain, reduce fever, fight infections, and improve skin health. Today, lemongrass oil remains popular in aromatherapy, skincare, natural medicine, and household cleaning products because of its versatility.

Its calming aroma may help relax the mind and body, promoting better sleep quality.

10 Side Effects of Lemongrass Oil

While lemongrass oil is beneficial, it must be used carefully. Here are the main side effects you should be aware of.

Direct application without dilution can cause redness, burning, or irritation because the oil is very strong.

Strong aromas sometimes trigger nausea or headaches in scent-sensitive individuals.

4. Eye irritation

5. Stomach upset (if ingested improperly)

Lemongrass oil should never be consumed directly. Ingesting it without medical supervision can cause vomiting, nausea, or toxicity.

6. Increased sensitivity in pregnant individuals

Pregnant women should avoid topical or internal use without medical guidance, as essential oils can affect hormones.

7. Interaction with medications

The oil may interact with medications, especially diuretics or those affecting the liver.

8. Photosensitivity

Although not severe compared to some oils, lemongrass can make the skin slightly more sensitive to sunlight.

9. Burning sensation on sensitive skin

People with eczema, psoriasis, or sensitive skin may experience increased irritation.

10. Toxicity with excessive use

Using too much essential oil (either topically or internally) may cause toxicity, especially in children and pets.
