Recognizing fresh Dây tea: A distinctive guide.
Dây tea is a type of climbing plant. The plant usually stays under 1m in height, but its vines can extend up to 2 – 3m, often wrapping around other trees.

Identifying dried Dây tea: A distinctive guide.
The easiest way to identify Dây tea is by examining the color of the dried leaves. Freshly dried Dây tea has a white hue, resembling mold on the surface due to the resin released during processing.
