Understanding Lemongrass
Lemongrass is a tall, slender plant with long, narrow leaves and a distinctive lemony scent and flavor. A staple ingredient in many Asian cuisines, lemongrass finds fame in teas, curries, and soups, earning its widespread recognition. However, its medicinal properties have brought it to the forefront of natural remedies.
How to Grow and Care for Lemongrass
Growing and caring for lemongrass is relatively easy, and it can be a rewarding addition to your garden or even in a pot on your balcony. Lemongrass is a tropical plant, so it thrives in warm, sunny conditions. Here’s a step-by-step guide on how to grow and care for lemongrass:
1. Choose the Right Location:
- Lemongrass thrives in full sun, so select a location that receives at least 6-8 hours of direct sunlight each day.
2. Planting Lemongrass:
- You can grow lemongrass from seeds, cuttings, or divisions. The easiest method for beginners is using cuttings or divisions.
- Plant lemongrass in well-draining soil with a pH level between 6.0 and 7.5.
- Dig a hole that’s about twice the size of the root ball of the lemongrass plant you’re transplanting.
- Place the lemongrass plant in the hole, covering the roots with soil, and water it thoroughly.
3. Watering:
- Lemongrass prefers consistently moist soil. Water it regularly, especially during hot and dry periods.
- Water deeply to encourage the development of a strong root system. However, make sure the soil doesn’t become waterlogged, as lemongrass doesn’t like sitting in standing water.
4. Fertilizing:
- Lemongrass doesn’t require excessive fertilization. You can use a balanced, slow-release fertilizer or compost to provide essential nutrients.
- Apply fertilizer in the spring and again in mid-summer.
5. Pruning:
- To encourage new growth and maintain a neat appearance, prune lemongrass by cutting off dead or damaged leaves.
- Harvesting lemongrass for culinary use can also serve as a form of pruning.
6. Controlling Pests:
- Lemongrass is relatively pest-resistant. However, you may encounter common garden pests like aphids or mealybugs. You can use neem oil or insecticidal soap to control them.
7. Winter Care:
- Cold winters prompt an annual approach to lemongrass cultivation in some regions. However, you can protect it during the winter by:
- Bringing potted lemongrass indoors or to a greenhouse.
- In the ground, you can cover the plant with a thick layer of mulch to insulate it from freezing temperatures.
8. Harvesting:
- You can start harvesting lemongrass when it reaches a suitable size, typically when the stalks are about half an inch thick.
- Harvest by cutting the stalks at the base using a sharp knife or scissors. Avoid taking more than one-third of the plant at a time to ensure continued growth.
9. Propagation:
- Dividing established clumps allows for propagating lemongrass. Dig up the plant, separate the clumps, and replant them in new locations.

Medicinal Benefits
Lemongrass, with its refreshing aroma and delightful flavor, offers more than just a culinary experience. It’s rich in bioactive compounds that provide numerous potential health benefits, making it a valuable addition to your diet and wellness routine.
1. Antioxidant Properties:
According to a study published in the Journal of Agriculture and Food Chemistry, lemongrass contains several antioxidants, such as chlorogenic acid, isoorientin, and swertiajaponin. These antioxidants scavenge free radicals in your body that may cause disease. This makes lemongrass a potential ally in protecting your cells from oxidative damage and preventing dysfunction of cells inside your coronary arteries.
2. Antimicrobial Properties:
Lemongrass possesses antimicrobial properties that can be harnessed to treat oral infections and cavities. Research published by the National Institutes of Health has demonstrated that lemongrass essential oil has antimicrobial abilities, effectively countering Streptococcus mutans bacteria, a major contributor to tooth decay. Further research has shown that lemongrass oil, in combination with silver ions, can work effectively against various types of bacteria and fungi in vitro.
3. Anti-Inflammatory Properties:
Inflammation is implicated in numerous health conditions, including heart disease and stroke. The anti-inflammatory benefits of lemongrass are attributed to two key compounds, citral and geranial. These compounds are believed to inhibit the release of inflammation-causing markers in the body, potentially reducing the risk of inflammatory-related diseases.
4. Potential Cancer Risk Reduction:
Lemongrass contains citral, a compound with potent anticancer abilities against some cancer cell lines. Various components of lemongrass help combat cancer either by inducing cell death directly or by enhancing the immune system’s ability to fight cancer. Lemongrass tea is sometimes used as an adjuvant therapy during chemotherapy and radiation, although this should only be done under the guidance of an oncologist.
5. Promotion of Healthy Digestion:
For upset stomach, stomach cramping, and digestive problems, a cup of lemongrass tea can serve as an effective alternative remedy. Research published by the National Institutes of Health demonstrated that lemongrass may also protect against gastric ulcers, potentially countering damage from substances like aspirin and ethanol, which are common causes of gastric ulcers.
6. Diuretic Effect:
Lemongrass is a known diuretic, helping the body eliminate excess fluid and sodium by promoting increased urination. It has demonstrated diuretic activity in animal studies, similar to green tea, without causing organ damage or side effects.
7. Blood Pressure Regulation:
In an observational study, men who drank lemongrass tea experienced a moderate decrease in systolic blood pressure and a mild increase in diastolic blood pressure. This suggests lemongrass may have potential in reducing high systolic blood pressure. However, individuals with heart problems should use lemongrass in moderation to avoid dangerous fluctuations in heart rate and blood pressure.
8. Cholesterol Regulation:
High cholesterol levels can increase the risk of heart attack and stroke. Research has shown that lemongrass oil extract can help lower cholesterol in animals. The extent of cholesterol reduction depends on the dosage, and further studies are needed to determine if lemongrass tea has similar effects.
9. Weight Management:
Lemongrass tea is sometimes used as a detox tea to boost metabolism and aid in weight loss. While most research on lemongrass and weight loss is anecdotal, lemongrass’s natural diuretic properties may help shed some pounds. However, it should not be consumed exclusively, as this can increase the risk of side effects.
10. PMS Symptom Relief:
Lemongrass tea is used as a natural remedy for menstrual cramps, bloating, and hot flashes. Although there isn’t specific research on lemongrass and PMS, its stomach-soothing and anti-inflammatory properties may offer relief. Additionally, lemongrass oil is considered useful in helping to cool the body, as mentioned in an article in the Journal of Advanced Pharmaceutical Technology & Research.
