Background

Lemongrass is grown in Guatemala, India, Paraguay, England, Sri Lanka, China, and other parts of Indochina, Africa, Central America, and South America. It has been used traditionally to lower high blood pressure and as an anti-inflammatory. In India, lemongrass is used as a medicinal herb and in perfumes. It is also used in Brazilian folk medicine in a tea called abafado, as a sedative, for gastrointestinal problems, and for fever. Lemongrass oil has a fresh, strong, lemon-like, and pungent odor and is used in deodorants, herbal teas, skin care products, fragrances, and insect repellents, and for aromatherapy.
Research is being conducted to examine the potential antimalarial, antioxidant, anticancer, antibacterial, antifungal, anti-inflammatory, and antiviral properties of lemongrass. Currently, there is very little scientific evidence investigating the use of lemongrass in humans.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (over 18 years old)
There is no proven safe or effective dose of lemongrass for adults. Traditionally, 1-2 teaspoons of lemongrass in six ounces of boiling water has been taken by mouth as a tea. Two grams of lemongrass herb, cut and powdered into one cup of boiling water, has also been taken by mouth. For high cholesterol, 140 milligrams of lemongrass oil in a capsule once a day for 90 days has been taken by mouth with no significant benefit. For sedation, lemongrass tea was taken by mouth with no significant benefit. For thrush, half a packet (12.5 milliliters) of dried lemongrass was used to make an infusion with 500 milliliters of boiling water. The infusion was boiled for 10 minutes and cooled. For the first treatment, patients drank 125 milliliters of lemongrass infusion and then drank 250 milliliters twice a day for a total of 10 days (a fresh infusion was made every 24 hours).

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Interactions

Interactions with Drugs
Lemongrass oil may increase absorption of drugs through the skin.
Lemongrass may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants (blood thinners) such as warfarin (Coumadin?) or heparin, antiplatelet drugs such as clopidogrel (Plavix?), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin?, Advil?) or naproxen (Naprosyn?, Aleve?).
Lemongrass may lower blood pressure and should be used cautiously with other drugs that alter blood pressure. Also, caution is advised in patients taking drugs that affect the heart, as this combination may alter the effects of the drug or cause unwanted side effects.
Lemongrass may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar. Patients taking insulin or drugs for diabetes by mouth should be monitored closely by a qualified healthcare provider. Medication adjustments may be necessary.
Lemongrass may interfere with the way the body processes certain drugs using the liver's cytochrome P450 enzyme system. As a result, the levels of these drugs may be altered in the blood and may cause increased or decreased effects or potentially serious adverse reactions. Individuals using any medications should check the package insert and speak with a healthcare professional, including a pharmacist, about possible interactions.
Lemongrass may also interact with analgesics (pain reducers), antibiotics, anticonvulsants, antifungals, anti-inflammatories, antimalarials (drugs used for malaria), antivirals, cholesterol-lowering agents, cholinesterase inhibitors (drugs that inhibit the enzyme cholinesterase), diuretics (drugs that increase urination), and vasodilators (drugs that widen blood vessels).
