A Culinary Overview of Centella Asiatica
Centella asiatica (Gotu kola or Indian pennywort) is a creeping perennial plant native to tropical regions of Asia and Australia, with a long history of use in both traditional medicine and food. Its use in cooking leverages both its unique flavor profile and its purported health benefits, which include being rich in antioxidants and vitamins. The leaves, which are the primary edible part, can be consumed raw or cooked and are a staple in many regional dishes.
Traditional Preparations and Regional Dishes
Across various cultures, Centella asiatica is integrated into everyday meals in diverse ways, showcasing its versatility. Its mild, slightly bitter taste is often balanced with other ingredients. Here are some of the most common applications:
-
Salads (Ulam/Sambai): In Malay cuisine, the leaves are used in ulam, a type of traditional vegetable salad served with rice and other dishes. In Aceh, Indonesia, it is a key ingredient in sambai oi peuga-ga. Raw, finely chopped leaves are also combined with shredded coconut, chili, and lime juice to create vibrant side salads known as mallung in Sri Lanka.
-
Drinks and Juices: Fresh Centella leaves are frequently blended to create refreshing and healthy beverages. In Vietnam, for instance, a sweet pennywort drink (nước rau má) is a popular item sold at markets. These drinks are valued for their cooling properties and nutritional content.
-
Curries and Stews: When cooked, the leaves become less bitter and impart a subtle, earthy flavor to the dish. In Bangladesh and India, a popular snack is a pakora-like fritter called Thankuni Patar Bora, made from mashed Centella and lentils. It is also simmered with coconut milk, lentils (dhal), and spices to create warming stews and porridges, such as the Sri Lankan kanda.
-
Garnishes: Due to their unique kidney-shaped appearance, fresh Centella leaves are an excellent garnish. They can be finely chopped or left whole to add a fresh, green finish to soups, noodle dishes, and curries.

Safety and Sourcing Considerations
When consuming Centella asiatica, particularly if foraging, it is crucial to properly identify the plant to avoid confusion with other, potentially toxic, species. The source of the plant is also important, as it can be sensitive to environmental pollutants. While generally regarded as safe for culinary use, excessive or long-term oral consumption, especially of concentrated supplements, has been linked to rare instances of liver injury. It is always advisable to consult a healthcare provider, especially for those with existing liver conditions or who are taking certain medications.
