Lemongrass Uses and Benefits

Lemongrass (Cymbopogon citratus) has long been used in traditional medicine systems for its potential health-supporting properties. The leaves and essential oil are traditionally used to help alleviate symptoms such as digestive discomfort, mild muscle pain, and stress.

Lemongrass essential oil is often used in aromatherapy and may offer a soothing, calming effect when inhaled [1]. When properly diluted with a carrier oil, it may provide temporary relief of minor aches and muscular tension [2].

In addition to its traditional uses, lemongrass is widely used as a natural flavouring in teas and cuisine and as a fragrance in soaps and cosmetics, as it is generally “Generally Recognised as Safe” (GRAS) by regulatory bodies for consumption [3].

How Does Lemongrass Potentially Benefit Health?

Lemongrass (Cymbopogon citratus) is a tropical herb widely used in traditional medicine and culinary practices, especially in Asian cuisine. Beyond its flavour and aroma, it has several potential health-supporting properties, although more scientific evidence, particularly robust human clinical trials, is needed to confirm many of these effects [4].

Here are some of the commonly cited potential benefits of lemongrass:

1. Potential to Support Red Blood Cell Production

Some studies suggest that drinking lemongrass tea may help support red blood cell production, possibly due to its natural iron and folate content [4]. However, it must not be considered a replacement for iron supplementation or definitive medical treatment for clinical anaemia.

2. Supports Skin and Hair Health

Lemongrass essential oil contains compounds with known antimicrobial and antifungal properties and is believed to help cleanse the skin [1]. When diluted with carrier oils like coconut or olive oil, it may also support hair nourishment and scalp health, given its traditional use as a tonic [4].

3. Traditional Use for Fluid Balance and Weight Management

Lemongrass is traditionally used as a natural diuretic, which may help reduce water retention [4]. Early research also suggests it may influence metabolic processes, though clinical evidence in humans remains limited and inconclusive for definitive weight loss [4].

4. Traditionally Used for Digestive Relief

In traditional medicine, lemongrass tea is used to relieve bloating, indigestion, and cramps [4]. The compound citral is thought to contribute to its calming effects on the digestive tract, potentially by acting as an antispasmodic [5].

5. Potential Role in Blood Pressure Regulation

Lemongrass is sometimes used as a natural remedy that may help support healthy blood pressure levels, possibly due to its potassium content and its traditional use as a diuretic [6]. It is crucial to understand that it should not replace prescribed anti-hypertensive medications [6].

6. Potential to Help Manage Stress and Promote Relaxation

Lemongrass tea is commonly consumed for its soothing aroma and calming effect, which may help reduce anxiety and promote relaxation [1]. This benefit is largely anecdotal and supported by aromatherapy principles, as robust clinical trials on its efficacy for anxiety are still emerging [1].

7. Antioxidant Properties and Ongoing Research

Preliminary studies have found that compounds in lemongrass, such as citral and eugenol, may have antioxidant and anti-proliferative properties [4]. While promising, these effects have primarily been observed in lab settings (in vitro)—this is not conclusive evidence for human cancer prevention or treatment, and should not be misinterpreted as such.

8. Traditional Use for Headache and Pain Relief

Some evidence suggests lemongrass may have mild analgesic (pain-relieving) properties [4]. Eugenol, a compound in lemongrass, has been studied for its potential to help regulate serotonin pathways, which are relevant to mood and pain perception [4].

Quick & Easy Lemongrass Tea Recipe

Enjoy the refreshing flavour and potential health benefits of lemongrass with this simple tea recipe:

Ingredients:

• 1–2 fresh lemongrass stalks
• 1 cup of water
• (Optional) Honey, lemon, or ice cubes

Instructions:

1. Wash the lemongrass stalks and cut them into 1–2 inch pieces.
2. Bring a cup of water to a boil in a small saucepan or kettle.
3. Add the lemongrass pieces to the boiling water.
4. Let it simmer or steep for 5–7 minutes to release the flavour.
5. Strain the tea into a cup.
6. Add honey or lemon for taste, if desired. Serve hot — or pour over ice for a refreshing cold version.

While drinking a cup of lemongrass tea may support digestion and relaxation, it is important to note: if you are pregnant, breastfeeding, or taking prescription medication, consult your doctor before regular or medicinal use [7].

Side Effects and Safety Precautions of Lemongrass

Lemongrass is generally considered safe when consumed in typical food amounts [3]. In herbal medicine, it is also commonly used as tea or in diluted essential oil form for topical use or aromatherapy [1].

However, some crucial precautions and potential side effects should be noted:

• Allergic Reactions: In sensitive individuals, lemongrass essential oil may trigger allergic reactions, including skin irritation or difficulty breathing, especially when inhaled in large amounts or used undiluted on the skin [2]. Discontinue use immediately if any such symptoms occur.
• Children’s Safety: Lemongrass-based insect repellents or essential oils should not be used on or around young children without professional guidance. Accidental ingestion of essential oils can be toxic and harmful [2].
• Topical Use Warning: Concentrated lemongrass essential oil must always be diluted with a carrier oil (such as coconut or jojoba oil) before applying to the skin, to avoid severe burns or irritation [2].
• Pregnancy and Breastfeeding: Pregnant or breastfeeding individuals should strictly consult a healthcare provider before using lemongrass in medicinal amounts. This is due to traditional concerns about a possible uterine-stimulating effect, which has not been fully established but warrants caution [7].

Expert Quote

“Lemongrass offers a variety of wellness benefits, from aiding digestion to calming the mind. However, when using it in essential oil or concentrated supplement form, it is paramount to adhere to proper dilution guidelines and be mindful of potential drug-herb interactions. Checking with a healthcare expert before regular therapeutic use is a wise and necessary step for safety and efficacy.”

Lemongrass is a versatile, aromatic herb valued in both traditional medicine and modern wellness practices. From its use in teas and essential oils to its role in skincare and digestion, lemongrass may offer a range of health-supporting effects, many of which are supported by preliminary scientific findings and centuries of traditional use [4].

However, like all herbal remedies, it should be used thoughtfully. While generally safe in food amounts [3], medicinal or concentrated use must be approached with caution, as it may carry risks—particularly for individuals who are pregnant, breastfeeding, or managing specific health conditions [7]. Always consult a qualified healthcare provider before incorporating lemongrass into your routine for therapeutic purposes.

With proper use and adherence to safety precautions, lemongrass can be a refreshing addition to your lifestyle—supporting well-being naturally and responsibly.
