Rattan Vine Leaves (Aganonerion polymorphum) are the edible leaves of the rattan vine plant, belonging to the Apocynaceae family. The plant is a climbing vine found in tropical regions of Southeast Asia. Rattan vine leaves are widely used in Vietnamese cuisine, particularly as a natural source of sour flavor in soups and hotpot dishes.
Characteristic Features
The leaves are oval to elongated, with pointed tips and smooth margins.
Young leaves are bright green, while mature leaves are darker green with a relatively smooth surface.
The plant grows as a climbing vine, with young stems that are soft and may release white latex when cut or broken.
Fresh leaves have a high moisture content and should be cleaned and trimmed to remove mature, wilted, or damaged leaves before use.
Good-quality leaves should be fresh and intact, free from insect damage, bruising, waterlogging, or abnormal odor.
