Side Effects of Lemongrass Tea

What are the possible side effects of lemongrass tea?


Lemongrass is a tropical perennial plant that yields aromatic oil. Dried lemongrass leaves are used as a lemon flavor ingredient in herbal teas, prepared either by infusion or decoction of 2-3 leaves in 250 milliliters of water.

Lemongrass typically grows to a height of 1 to 1.5 meters, reaching 3 meters at flowering.

The plant grows in a wide range of climatic conditions and soils.

For example, in the Philippines, it grows in almost any place where there is adequate sunlight and proper drainage.

An estimated 55 varieties of lemongrass exist worldwide, however, only those known as West Indian and East Indian are suitable for making soaps, cooking, lotions, perfumes, and production of essential oils.

Oral Thrush

Lemongrass reduces the incidence of thrush, according to the Memorial Sloan Kettering Cancer Center. Scientists established that an oral rinse that was administered 3 times per day was more effective than gentian violet (a dye that has antifungal, antibacterial, and anthelmintic properties).

Thrush is a common infection caused by an overgrowth of Candida albicans yeast. Symptoms of oral thrush include:

  • difficulty swallowing;
  • white patches in the mouth which can be wiped off;
  • angular cheilitis (cracks at the corners of the mouth);
  • soreness and redness on the inside of the mouth;
  • an unpleasant taste in the mouth which can be salty or bitter;
  • a burning sensation on the tongue.

Circumstances that encourage the overgrowth of Candida albicans to include:

  • some cancers and their treatment;
  • hormonal changes;
  • immune suppression;
  • medical conditions like Human immunodeficiency virus infection and diabetes;
  • drugs’ side effects, particularly steroids and antibiotics.

Anti-Inflammatory Properties

Inflammation is a process in which white blood cells (also called leukocytes) can protect against foreign substances and infection.

But, if the inflammatory process goes on for too long, it can lead to certain diseases like lupus, rheumatoid arthritis, stroke, or heart disease.

A tea made from dried lemongrass reduces nitric oxide (a signaling molecule that has an important role in the pathogenesis of inflammation) levels, according to a 2010 study that was issued in the “Journal of Medicinal Food.”


This herb is a great source of vitamin C, a vitamin that has an essential role in collagen synthesis.
