Gotu kola, Centella asiatica

Gotu kola is a well-known plant in Asia. It is an ancient Ayurvedic herb that is still used in India and other tropical Asian countries both as a food and as a medicinal plant.

Korea is a pioneer country in cosmetics, and that is why many things are transferred from Korean cosmetics to Europe and America and then forwarded to the rest of the world.

Gotu kola has many names

Gotu kola actually goes by many different names; Centella asiatica, Hydrocotyle asiatica, Indian pennywort, Asiatic pennywort, coinwort. I use the name gotu kola for the plant here because I’m used to it. Other names of the plant may also appear in the INCI -lists and packaging of cosmetics. That’s why it’s good for you to know the plant’s many names.

The abundance of gotu kola names is also emphasized by the fact that centella, or gotu kola, is also called brahmi in India. We are used to use name brahmi when talking about Bacoba monnieri, which is a completely different plant, Brahmi. The name brahmi comes from the Sanskrit word Brahma, which means universal consciousness. Because both Centella asiatica and  bacoba have effects on consciousness and mind in Ayurveda, both plants are called brahmi in India.

The names of these two plants may vary depending on the region. Gotu kola is commonly called Brahmi in North India. In South India, on the other hand, Bacoba monnieri is also called Brahmi. It must therefore be considered where in India the name Brahmi is used and which plant is used. However, both plants can quite justifiably be called Brahmi. You can read more about it on the Banyan Botanicals website.

According to another explanation, the plant got its name manduki (like a frog) because it grows where frogs live.

Gotu kola is considered a weed in Asia, which spreads as a covering plant over very large areas. It is a rather modest plant with round, serrated leaves. I can hardly see the small purple flowers of Gotu kola under the lush foliage. Sometimes the flowers can also be white or purple.
