beautiful pond plant, and much more.... These plants are natural chemical factories. They have a chemical, like celery, that helps the aorta and blood vessels relax. They do that by increasing the amount of nitrous oxide available and that can lower blood pressure. In India, Centella has been used for that purpose for some 3,000 years. Nice of modern science to confirm it. The plant has a host of other properties as well from affecting blood cell development to wound care to reducing edema. It’s a little plant that can. By the way, Centella means "little coin" because the leaf surface is shiny and reflects light (and why all of the money names.) Erecta is upright. Hydrocotyle is from Greek meaning flat cup — the leaves can hold water.
Culinary: Pennywort have a slight bitter tang and are good to eat combined with shallots and lightly seasoned. Another way this leaf is taken is as a sweetened beverage. Look in the refrigerator section of large Asian grocery stores and there, among the canned soft drinks featuring tropical fruit juices, you will also find pennywort drink. The canned version does not appeal much in colour or flavour; but the drink made with fresh pennywort leaves is entirely different and very refreshing. Frothy and bright green, its piquant herb flavour sweetened by the addition of sugar syrup and poured over crushed ice, it quenches thirst and does you good at the same time. In Vietnamese areas, certain shops make it to order. If you have a supply of leaves, it is easy enough to make at home.”
Folklore and History: pennywort tea is said to have helped one Chinese master live to 256 (Chinese history). It also helped a Sultan fulfill his husbandly duties to his 50 wives….. That should make it disappear from lawns…lol
