9 Least Known Health Benefits Of Citronella Oil (Lemongrass)

Citronella oil is one of the most popular essential oils, derived from the leaves and stems of Cymbopogon, commonly known as lemongrass. Among the approximately 50 species of lemongrass, Cymbopogon citratus is specifically used for producing citronella oil. This grass is widely cultivated for its lemon-like aroma and disinfectant properties, making it valuable for both culinary and medicinal purposes.

Lemongrass has tall, slender leaves, with magenta-tinted stems. It is native to India, Thailand, Malaysia, and Sri Lanka. In Brazilian folk medicine, the plant is believed to have anticonvulsant, antianxiety, and hypnotic effects. Traditional Indian medicine also highlights citronella oil for its analgesic, anti-inflammatory, antibacterial, antipyretic, and antifungal properties.

The herb contains naturally occurring compounds such as citronellal, myrcene, nerol, geraniol, and terpinolene. Studies have also revealed the presence of flavonoids and phenolic compounds, including luteolin, quercetin, and apigenin, which contribute to its therapeutic potential.

Health Benefits of Citronella Oil

# Alleviates Depression

Depression and anxiety are severe mental health issues, and herbal remedies can be an effective way to manage them. Research suggests that citronella oil exhibits significant antidepressant effects, comparable to the drug imipramine. Active compounds like myrcene, citronellal, and geraniol help soothe nervous conditions and reduce inflammation, effectively addressing depression and anxiety.

# Relieves Muscle Spasms

Citronella oil contains terpenes, ketones, esters, and alcohols, along with flavonoids and phenolic compounds, making it a valuable component in aromatherapy. Massaging the affected area with citronella oil blended with a carrier oil provides a warming and spasmodic effect, relieving muscle pain and spasms.

# Detoxifies the Body

This oil acts as a natural detoxifier due to its methanol content. It aids in cleansing the pancreas, digestive system, kidneys, and liver. The plant's decoction is also known to promote sweating, which helps eliminate excess oil, toxins, and water from the body, thus supporting overall health.

# Repels Mosquitoes

The Aedes aegypti mosquito, a carrier of vector-borne diseases like dengue and yellow fever, has developed resistance to certain pesticides. Studies indicate that citronella oil is more effective in repelling Aedes aegypti mosquitoes than DEET, making it an excellent natural insect repellent.

# Fights Infections

Lemongrass oil contains two key monoterpenic aldehydes—geranial and neral—known for their antimicrobial properties. These compounds are particularly effective in vapor form, combating Gram-positive and Gram-negative bacteria and fungi.

# Treats Gastrointestinal Disorders

Citronella oil has long been used to address gastric ulcers and stomach discomfort. It protects the gastric mucosa from damage caused by harmful agents like ethanol. In Brazilian folk medicine, the oil is widely employed to treat a variety of stomach-related ailments.

# Supports Kidney Health

Research suggests that citronella oil helps prevent kidney damage caused by aminoglycosides, a class of antibiotics derived from Streptomyces bacteria. Its strong flavonoid content and antioxidant properties protect against oxidative damage, promoting kidney health.

# Reduces Inflammation

This herb, often used in traditional cuisines, is known for its anti-inflammatory effects. Its polyphenols, including flavonoids and tannins, reduce nitric oxide production in activated inflammatory cells without impairing cell functionality. This reduction in nitric oxide helps alleviate inflammation and related conditions.

# Enhances Blood Circulation

Studies show that lemongrass oil contains antihypertensive agents and methanolic substances that relax vascular muscles, including blood vessels, veins, and arteries. By relaxing these muscles, the oil improves blood flow and promotes overall circulation throughout the body.
