You are here: Home / Herbs / Thankuni: The Longevity Herb

Thankuni is a creeping perennial that belongs to the Apiaceae family, and that goes by several other names. It is a relative of various other better-known herbs such as parsley and cilantro. Its aliases include its botanical name, Centella asiatica as well as pennywort. While it has been naturalized to other parts of the world, it grows primarily in Southeast Asia and prefers humid and swampy climates. In some parts of the world, many know thankuni by another alias: gotu kola.

The kola part of the name may seem to imply a relationship with the kola nut, but the kola nut — which is the flavoring in cola sodas — comes from an entirely different plant.

Indians and Chinese have used this herb for millennia. In Ayurveda, it is considered a kind of anxiolytic. You can find thankuni documented in ancient Sanskrit texts as a remedy for cardiovascular illness as well as for respiratory ailments like bronchitis. Chinese legend has it that a herbalist who consumed thankuni lived for over 250 years. The herb is still used in traditional Chinese medicine. Thankuni became popular in Sri Lanka as well when people noticed that elephants seemed to be attracted to it. Elephants are known to have long lives.

In recent years, thankuni has gotten a significant amount of attention with the popularity of certain supplements for cognition known as nootropics. Its purported benefits for improved brain function are why many in the West know of this herb’s existence.

Most of the world’s supply of thankuni comes from India, though Madagascar is also known to produce the best quality.
