Gotu kola (also known as pennywort or marsh penny) is a perennial herb found in wet, tropical areas around the world. The plant grows close to the ground, reaching heights up to 30 centimeters, with heart-shaped or circular leaves, 1 to 7 centimeters in diameter, and small, white or pink colored flowers, which grow in groups of three to four. The fruit can be ovate or spherical, measuring 2 to 5 millimeters in diameter. The leaves and stems are used for health purposes.
Gotu kola contains a mixture of triterpenes, volatile oils, and plant sterols.
Gotu kola is consumed as a vegetable in large quantities and has no known toxicity. For medicinal purposes, a common recommendation is 600 mg of dried leaves, three times per day.
