What is lemongrass?
Lemongrass is an aromatic culinary herb used in many Asian dishes and has a long history of medicinal use. It was considered by Paracelsus, the renowned Swiss German physician from the 15th century, to be a cure-all and it was believed to be his favorite and most revered herb.
In India and Sri Lanka, lemongrass leaves are steeped with other herbs to treat fevers, diarrhea, and stomachaches. Lemongrass is one of the most popular herbs in Brazil and the Caribbean for nervous and digestive problems. In Chinese medicine, lemongrass was used medicinally for similar purposes. Today, lemongrass is used to treat a variety of conditions.

The health benefits of lemongrass according to research
1. Digestive Health
Lemongrass is commonly taken as a tea for digestive problems, helping to relieve cramps, indigestion, flatulence, bloating and diarrhea. It is one of the most used plants in the traditional medicine of Brazil for the treatment of nervous and gastrointestinal disturbances.
In a study conducted in 2006, scientists found presence of anti-diarrhea activity in lemongrass and its main constituent, citral. The results of the preliminary study provided support for the traditional use of the herb in treating diarrhea.
2. Heart and Circulatory Health
Lemongrass is rich in potassium and may help lower and regulate blood pressure. It may also help reduce the absorption of cholesterol. High cholesterol can lead to the buildup of plaque in artery walls which in turn can lead to coronary artery disease, heart attack, stroke or other heart conditions. A study conducted by the University of Wisconsin found that people with high cholesterol who were supplemented with lemongrass saw a reduced in cholesterol levels and blood fats.
3. Immunity and Overall Health
The volatile oils of lemongrass contains a number of constituents such as geraniol and limonene, which have antimicrobial properties. In vitro studies have shown that it may be a cost-effective treatment option against antibiotic-resistant strains such as Staph infections. Lemongrass is also thought to have antioxidant properties as well as antiseptic compounds that are believed to fight against certain bacteria.
Compounds found in lemongrass, such as citral, have demonstrated activity against asthma, allergies and cancer. According to a study published in 2009 in the Fundamentals of Clinical Pharmacology, citral slows the growth of breast cancer cells.
