Its shape is similar to that of honeysuckle, one of which has small yellow flowers and pod-shaped fruit, and the other has small purple flowers. However, both of them are very slender. The stems are only the thickness of pencil lead, more than 20 centimeters high, the leaves are fine and fragmentary, the size of small nails, and the roots have a bad smell.

Alias "Hu Manteng, Gelsemium Uncaria, Big Tea Medicine, Cannabis Leaf, Sophora flavescens, and Euphorbia fischeriana"
