It's also important to wash空心菜 thoroughly to remove any pesticide residues or contaminants, especially since it's often grown in water-rich environments.

在传统文化中，空心菜 has been used in traditional medicine for its healing properties. In some Asian cultures, it is believed to cool the body and reduce internal heat, making it popular in summer dishes.
