Standardized: gotu kola
Centella asiatica (L.) Urb.1
Hydrocotyle asiatica L.1
Gotu kola is known throughout the Asian world as a potent medicinal herb and a tasty food. It has been utilized for thousands of years in both traditional Chinese medicine (TCM) and Ayurveda for its wound healing properties and for its positive effect on memory and focus. Just recently its value has been recognized in the U.S. as an herb that supports cognition and vascular health.
Centella asiatica is a low growing creeping perennial herb that likes hot, moist climates in the South and Southeast Asian tropics.3 It is native to India, Japan, China, Indonesia, South Africa, Sri Lanka, and the South Pacific.1,4 Centella loves to grow near slowly moving water (one of its common names in Ayurveda is 'mandukaparni' which means frog-leafed as this plant grows in swampy areas).3 It has small round bright green leaves with white, light purple or pink flowers, and produces an oval shaped fruit.4 As a member of the carrot or Apiaceace family, it is related to many other popular foods and medicinal spices such as parsley (Petroselinum crispum), cumin (Cuminum cyminum), fennel (Foeniculum vulgare), angelica (Angelica archangelica), and cilantro (Coriandrum sativum). In Spanish is it referred to as 'sombrerito' which means little hat and alludes to the shape of the leaf.1 In the Sri Lankan Singhalese language, 'gotu kola' means cup-shaped leaf. In Sri Lanka it is common knowledge that elephants, who have a reputation of a long life and a great memory, eat the plant. The locals follow their example, eating a few leaves a day.3,5
Gotu kola could possibly be confused with the caffeine-containing kola nut (Cola nitida),4 or bacopa (Bacopa monnieri), the latter often sold under the same Ayurvedic name 'brahmi' or 'mandukaparni'. However, gotu kola is certainly not a stimulant like kola nut and is in an entirely different family than bacopa.2,3 These two plants are confused however, because, in Ayurveda, they do have similar energetic characteristics.3
Cultivation And Harvesting
India produces most of the gotu kola for commerce, although Madagascar is thought to produce superior quality.5
History And Folklore
Gotu kola (Centella asiatica) has been used for thousands of years in India, China, and Indonesia.4 It is used in Ayurveda to soothe mental turbulence. Further, it is used externally for skin issues.2 It is one of those herbs that is tri-doshic or brings balance to all three of the Ayurvedic body types, vata, pitta, and kapha.3
Gotu kola’s ancient use is recorded in the Chinese Shennong Herbal (1st-2nd century CE).5 It is referred to as 'the fountain of life' in China as a legend boasts that a gotu kola-eating herbalist lived for over 200 years.4 This herb, called 'ji xue cao', is used in traditional Chinese medicine (TCM).
It is commonly eaten as a salad green, eaten raw and sold as fresh juice in many Asian countries.3 Rich in nutrients, gotu kola is a nourishing plant that is sweet and bitter in flavor, and is often eaten in a variety of Asian dishes. A typical dish consists of shredded gotu kola leaves, shallots, lime juice, chili, and coconut flakes.6
