Heleocharis tuberosa schultes, BI
The water chestnut, bi qi, is
also known as ma ti (horse hoof). It grows in water and has delicate leaves
and stems. The edible part is in the corm, which grows in the mud and is
shaped like a flattened ball.
The top of the corm has a pointed sprout on it. The surface of the corm is
dusty red or dusty brown and when dry appears to have stripes around it. A
light brown thin membrane is attached to these stripes.
Inside the corm the flesh is pale pink, containing a lot of juice, and of
sweet flavor. The corms are dug up in the autumn. The fruit's flavour is
sweet but insipid and of a cool nature.
The water chestnut can cool a fever, reduce phlegm, promote saliva and help
lower blood pressure. It contains starch, protein, fat, calcium,
phosphorous, iron, vitamin C, etc.
