Plant Profile and Characteristics
Gotu Kola, scientifically known as Centella asiatica, is a low-growing perennial herb native to tropical and subtropical regions of Asia, Africa, and parts of the South Pacific. Historically, it has played a significant role in Ayurvedic, Traditional Chinese, and Indonesian medicine for its reputed ability to revitalize the mind and body. The name “Gotu Kola” is derived from Sri Lankan Sinhalese and translates to “cup-shaped leaf,” an apt description of its distinctive foliage.
Taxonomy and Classification
- Kingdom: Plantae
- Clade: Angiosperms
- Order: Apiales
- Family: Apiaceae (or Umbelliferae)
- Genus: Centella
- Species: Centella asiatica
Its membership in the Apiaceae family places it among other aromatic and medicinal plants like parsley, coriander, and fennel, though its morphological characteristics differ significantly.
Physical Appearance
Gotu Kola is a creeping herb that typically grows close to the ground, forming a mat-like spread in moist, marshy habitats. It has thin, green stems that can extend outward, sending down roots at nodes where they come into contact with the soil. The leaves are small, fan-shaped, or kidney-shaped, with serrated edges. Each leaf has a smooth, glossy upper surface and conspicuous veins radiating from the center.
The herb rarely grows taller than about 15 centimeters (6 inches), although its runners can stretch more widely. Tiny inconspicuous flowers—ranging from white to light pink—emerge in clusters around the leaf axils. Over time, these flowers develop into small, oval fruits containing the herb’s seeds. While the blossoms are rarely noticed, their presence is vital for propagation.
