Gotu kola is found growing in swampy areas of most tropical and subtropical countries, including parts of India, Pakistan, Sri Lanka, Madagascar, South Africa, the South Pacific, and Eastern Europe.
Gotu kola grows best in moisturized marshlands, such as on riverbanks. Tropical climate conditions are also required, as this is its natural habitat. However, commercial gotu kola tends to be harvested from the wild rather than grown in nurseries or in specific fields.

Gotu kola is a perennial, herbaceous creeper that has small fan-shaped green leaves, with white or light purple-to-pink or white flowers, and it bears small oval fruit.
Gotu kola (Centella asiatica) is a member of the Apiaceae family, which comprises around 434 genera and 3,700 species of flowering plants, including carrot (Daucus carota), celery (Apium graveolens), and parsley (Petroselinum crispum).
Varieties and Subspecies of Gotu Kola
The Centella genus consist of only three species that can be found growing wild in many areas of the world, slightly varying in appearance depending on their surrounding conditions. Despite this, it is typical for their roots to give rise to reddish stolons. C. asiatica does not have any botanical varieties or subspecies.
Gotu kola first appeared in medicinal lore as part of the Indian Ayurvedic medicinal system, around 1,100 - 500 years BCE. Over the centuries, gotu kola has been used as a leafy green vegetable in Bangladesh, Thailand, and Sri Lanka. It wasn't until the late 19th century, however, that it became recognized as a valid, botanical medicine.
Gotu kola was carried by tiger hunters in India as a way of healing potential wounds resulting from encounters with these animals.
It has been referred to as the "fountain of life" because it is said that a Chinese herbalist who took gotu kola lived for two centuries.
Gotu kola is one of the most cultivated herbs in Southeast Asia, with India being its biggest producer. It is grown for both herbal medicine and culinary purposes. Gotu kola tends to have low yields, usually producing just 1,000 pounds (450 kg) per acre.
In addition to being used in food and medicine, gotu kola can also be used as a mosquito repellent. The oil of the plant has also been known to be used in the production of soaps and shampoos.
