Harnessing the Power of Lemongrass: Health Benefits and Uses

Can incorporating lemongrass into a diet help individuals manage anxiety, colds, fever, inflammation, and insomnia?

Lemongrass

Lemongrass, or lemongrass or citronella, is a tall grass-like herb commonly used in Southeast Asian cooking. The lower stalks and bulbs of the plant have a fresh, clean, lemony scent that is sometimes added to marinades, teas, curries, and broths. In addition to its flavoring use, lemongrass’s essential oils are used for medicinal purposes, supported by scientific evidence.

Benefits

Lemongrass has been shown to help with common ailments, such as anxiety, colds, fever, inflammation, and insomnia. It can be eaten, rubbed on the skin, or inhaled as an aromatherapy treatment. When taken orally, it is often used to calm stomach discomfort and other gastrointestinal issues, including cramps and vomiting. (DeFilipps, R. A. et al., 2018) When used as a tea, it protects the stomach lining by treating stomach ailments, indigestion, and gastric ulcers. (Khan, Nida. 2020) Lemongrass or oil is applied to the skin to treat headaches and musculoskeletal pain. As an aromatherapy treatment, the oil extract may be inhaled to treat muscle pain, infections, colds, and flu symptoms. Consumed it can help treat:

• Musculoskeletal pain
• Sleeplessness
• Rheumatism
• Cough
• Common cold
• Fever
• Anxiety
• Hypertension
• Diabetes
• Epilepsy
• Cancer prevention

However, a few studies support certain lemongrass benefits. Research has suggested that lemongrass oil added to a hair tonic may reduce dandruff. However, more studies are needed to confirm. (Chaisripipat, W. et al., 2015)

Essential Oil

Lemongrass essential oil has been studied and has been found to contain significant bioactive compounds that include:

• Citral
• Isoneral
• Isogeranial
• Geraniol
• Geranyl acetate
• Citronellal
• Citronellol
• Germacrene-D
• Elemol

These compounds contain antifungal, antibacterial, antiviral, anticancer, and antioxidant properties. (Mukarram, M. et al., 2021) Research also shows that essential oils can be therapeutic agents for treating inflammatory skin conditions and help reduce dandruff because of their antimicrobial and anti-inflammatory properties. They can also inhibit the growth of the fungi associated with causing dandruff. (Khan, Nida. 2020)

Nutrition

One tablespoon of fresh lemongrass provides around five calories, most from carbohydrates/fiber and protein. (U.S. Department of Agriculture, 2018) It is a source of fiber, carbohydrates, and vitamins A, B, and C, strengthening the body’s immune system, repairing tissue damage, and promoting cell division. It also contains:

• Magnesium – Necessary for protein synthesis, glycolysis, and muscle activity,
• Selenium – Necessary for cognitive function and fertility.
• Phosphorus – Necessary for DNA/RNA and cell membrane synthesis.
• Zinc for wound healing, growth, and development. (Khan, Nida. 2020)

Minerals include:

• Calcium – 3 milligrams
• Potassium – 34 milligrams
• Manganese – 0.2 milligrams
• Magnesium – 2.9 milligrams
• Iron – 0.4 milligrams

It also provides small amounts of vitamins, including A and C, folate, and niacin. However, lemongrass-flavored oil contains significantly more calories because it usually combines cooking oil with lemongrass extract.

Preparation and Storage

Lemongrass is becoming easier to find in stores. When choosing lemongrass, look for firm green stalks with healthy-looking bulbs attached. Some stores may sell the stalks with a good portion of the top removed. This is fine, as many recipes require using the bottom of the stalk or the bulb. To use lemongrass in teas, soups, broth, or other liquids, crush the stalks’ bottom area to release the aromatic oil. Then, immerse the pieces in the liquid to release the oils. Remove the stalks before eating or drinking the beverage. In other recipes, chopping or mincing the bulb or lower area of the stalks may be necessary before adding to a curry, salad, marinade, or stir-fry. Lemongrass can be wrapped in plastic and refrigerated for two to three weeks or frozen for up to 6 months.

Potential Side Effects

Lemongrass is safe for most when consumed in typical amounts in food. However, some concerns may arise when using it for medicinal purposes.

• Used topically, lemongrass may cause skin irritation.
• Additionally, consuming high amounts of lemongrass may cause dizziness, drowsiness, dry mouth, excess urination, and increased appetite. (Memorial Sloan Kettering Cancer Center, 2022)
• High amounts of essential oil can damage liver and stomach mucous membranes, and excessive tea intake may also affect kidney function. (Memorial Sloan Kettering Cancer Center, 2022)
• It is recommended that pregnant women should avoid lemongrass.
• Additionally, individuals undergoing chemotherapy should avoid lemongrass because it may interfere with the actions of some chemotherapeutic agents.
