Health Benefits of Lemongrass Tea

Lemongrass, with its bright citrusy flavor, makes a delicious herbal tea that’s both refreshing and soothing. This hardy perennial grows easily in gardens or indoors in pots, thriving in full sunlight, fertile soil, and with regular watering. While lemongrass carries a lemon scent, its flavour is milder and sweeter, making it a popular ingredient in Thai and other Asian cuisines.

Beyond its culinary uses, lemongrass has a history of traditional use in some cultures. One of the simplest ways to enjoy lemongrass is as a tea: chop the fresh grass, add it to boiling water, and steep for a few minutes. This soothing beverage offers potential benefits for overall well-being, but it is not a replacement for medical treatment.

Potential Benefits of Consuming Lemongrass Tea

Supports Digestion

Lemongrass contains a substance called citral, which may help with indigestion [1]. Historically, it has been used in various traditional medicines, including Chinese medicine, to soothe the stomach and support the regulation of the digestive system. Animal studies suggest that lemongrass tea may also help protect against gastric ulcers [2].

Source of Antioxidants and Potential Cellular Support

Lemongrass tea incorporates a range of antioxidants, such as chlorogenic acid, isoorientin, and swertiajaponin, that can assist your body in fighting disease-causing free radicals [3]. Such antioxidants may play a role in general cell protection, which is why consuming lemongrass tea is often associated with internal detoxification and cleansing. Certain compounds found in lemongrass have been studied in laboratory settings for their potential to target free radicals, which are implicated in cell damage and premature ageing. However, these are preliminary findings, and more human clinical trials are needed [4].

May Support Heart Health and Lower Blood Pressure

Lemongrass is a natural source of potassium, a mineral that helps regulate fluid balance and may promote healthy blood circulation. This effect can contribute to lowering blood pressure in some individuals. It acts as a natural diuretic, which helps the body eliminate excess sodium and fluid. Some research also suggests that compounds in lemongrass may inhibit the absorption of cholesterol in the intestines, thereby offering potential support for heart health [5]. Individuals already taking blood pressure medication should monitor their intake and consult a physician, as the combination could potentially lead to blood pressure dropping too low.

Boosts Metabolism and May Aid Weight Management

The advantages of drinking lemongrass tea include its use as a supportive aid in weight management, as it may enhance metabolic activity, helping you to potentially digest food more efficiently. This effect, combined with its action as a natural diuretic, means it aids in the removal of surplus water weight from the body. It should be noted that lemongrass tea is not a miracle weight-loss solution but a healthy, low-calorie beverage that supports a balanced diet and exercise regimen.

Enhances Skin and Hair Health

Lemongrass contains beneficial compounds, including the precursors to Vitamin A and Vitamin C, both of which are essential for maintaining healthy skin and hair. Furthermore, lemongrass has documented antibacterial and antifungal properties, making it an effective ingredient in topical applications to cleanse the skin [6]. To use topically, lemongrass oil must always be combined with a carrier oil such as coconut or olive oil before applying them to your skin.

Antibacterial and Antifungal Properties for Cold and Flu Relief

Lemongrass’s established antimicrobial properties may help alleviate symptoms of colds, coughs, and flu. When combined with ingredients like ginger, cloves, and turmeric, it is traditionally believed to help break down mucus and phlegm caused by congestion due to its warming and soothing qualities.

Potential for Oral Health Support

Lemongrass tea offers wellness benefits with antimicrobial properties that may aid in the treatment of tooth infections and cavities. A 2012 study noted that essential oil from lemongrass demonstrated the ability to fight Streptococcus sanguinis bacteria, which is a significant factor in tooth decay [7]. This suggests a potential role for lemongrass in supporting oral hygiene, though it is not a substitute for brushing, flossing, or regular dental care.

May Help Relieve Anxiety

Sipping hot tea can be relaxing for many people, but lemongrass tea may offer additional benefits that help alleviate anxiety. The scent of lemongrass may help people with anxiety, as suggested by its use in aromatherapy [8]. While some people use lemongrass essential oil to relieve stress and anxiety, it’s important to understand that its effect is primarily calming, and more clinical research is needed to fully confirm this benefit.

Eases Menstrual Discomfort

Traditionally, lemongrass tea has been used to help soothe menstrual cramps and hot flashes. Due to its potential to stimulate blood flow, diabetic individuals and pregnant or nursing women should consult a doctor before consuming it.

How to Make Lemongrass Tea

Start slowly: Begin by drinking one cup per day to minimise any risk of side effects. If you tolerate it well, you can increase your intake gradually. If you notice any adverse effects, reduce your consumption or stop altogether.

Lemongrass tea recipe:

• Add 1 to 3 teaspoons of fresh or dried lemongrass to 1 cup of boiling water.
• Allow at least five to ten minutes for the tea to steep to extract the beneficial compounds.
• Strain the tea.
• Serving: Enjoy the tea hot or add ice cubes to make a refreshing iced lemongrass tea.

Possible Side Effects and Risks

It is crucial to be aware of the potential side effects and risks associated with consuming lemongrass tea, especially in large quantities or if you have pre-existing health conditions.

• Allergic Reactions: Some people may experience skin rashes, itching, or swelling after consuming or having topical contact with lemongrass or its oil.
• Low Blood Pressure (Hypotension): As a natural vasodilator and diuretic, lemongrass tea may lower blood pressure. This could be risky for individuals already on blood pressure-lowering medications or those who naturally have low blood pressure, potentially leading to dizziness or fainting.
• Gastrointestinal Upset: Drinking lemongrass tea in large quantities can lead to stomach cramps, nausea, or diarrhoea. It is best consumed in moderation.
• Pregnancy and Breastfeeding Concerns: Lemongrass tea is generally not recommended for pregnant women as it may stimulate uterine contractions or menstrual flow. Nursing mothers should also avoid it until more safety data is available. Always consult your healthcare provider first.
• Kidney Issues: Lemongrass has diuretic properties. Excessive consumption over a long period may potentially put a strain on the kidneys in susceptible individuals. If you have a kidney condition, consult your physician.

Lemongrass tea is a refreshing drink with many potential health benefits. While many of the current studies on the isolated compounds in lemongrass are preliminary (in-vitro or animal-based), it remains a valuable part of a balanced diet. Lemongrass can be used in a variety of dishes, including soups and stir-fries, as well as consumed in tea form.
