The scientific name of Dilizi is water chestnut.

"Di Pear" has many scientific names, including water chestnut, peony root, peony root, black taro root and water chestnut root. In ancient times, it was called Fuchi, commonly known as horseshoe, and also known as ground chestnut. It got its name because it is shaped like a horseshoe and resembles a chestnut. Calling it a horse's hoof only refers to its appearance; saying it resembles a chestnut means not only its shape, but also its nature, flavor, ingredients, and functions. It is also called ground chestnut because it bears fruit in mud.

Taboos

1. Children with weak digestion should not eat it.

2. Water chestnuts are raw and cold foods, so those with spleen and stomach deficiency and coldness and blood stasis should not eat it.

3. Water chestnuts should not be eaten raw, because water chestnuts grow in mud, and there may be more bacteria and parasites attached to the outside and inside. Therefore, they must be washed and cooked thoroughly before eating, and they must be boiled. Ripe water chestnuts are sweeter.
