1. Origin and description

Wild Betel Leaf is a perennial herb in the Piperaceae family and is widely cultivated as well as found growing naturally in Vietnam. The plant prefers moist, shaded environments. Its creeping stems have visible nodes, and new roots may develop from these nodes.

The leaves grow alternately. Each leaf is broadly ovate to nearly round, with a heart-shaped base and a pointed tip. When crushed, it releases a characteristic aromatic scent. The flowering structure is a small spike.

The aerial parts can be harvested throughout the year and used fresh or dried. Good dried material should retain a natural color and aroma, be free from mold, and contain minimal foreign matter. Store it in a dry, well-ventilated place.
