Tripterospermum cordatum's Chinese name means "double butterflies". It is mistakenly thought to be an animal by looking at the name, but it is an herb that can cure lung diseases.

When the Tripterospermum cordatum is young, two leaves are attached to the ground, like a butterfly, and the veins on the leaf surface are like double lungs. Therefore, it is also called lung-shaped grass.

The Tripterospermum cordatum is a twining herb. After it grows up, it usually grows around other plants, giving people the impression that it is a harmful plant. However, it is wrong. Instead, it is a medicinal plant.

According to records, people began to use it before the Ming Dynasty. The whole plant of Tripterospermum cordatum can be used as medicine. It is often used for the treatment of various lung diseases such as cough with lung fever, consumption and hemoptysis, and lung carbuncle.
