The stem, leaves and roots are edible.
It is called “pegaga” in Malaysia, where it is used in salads and in some rice dishes, and a drink is often made from it, or it can be used in raita.
Vietnamese tend to use a variety called Hydrocotyle or Centella javanica, with larger leaves.
Many health benefits are attributed to it.
The Brahmin class in India believed that it improved their memory.
Sometimes called “Water Pennywort”, but that is perhaps best reserved for a variety that grows in shallow water, with its leaves floating on the surface, and form a dense mat on the edge of ponds, streams, etc. Water Pennywort is native to North America, invasive in Australia and Europe, particularly the Netherlands. In North America, it’s a protected plant in many jurisdictions.
