Abrus mollis is a common leguminous vine medicinal plant in southern China

Abrus mollis is a twining vine of the genus Abrus in the Fabaceae family, named for its stems and leaves being densely covered with soft hairs; in folk usage it is also often called hairy chicken-bone grass. It is mainly distributed across southern China, and mostly grows on hillside open forests, at the edges of thickets and in roadside grassland, preferring warm and humid climatic conditions.

In appearance, the stems and branches of Abrus mollis are slender and soft, and it can twine around other plants or supports to grow upward; the leaves are even-pinnately compound, with opposite leaflets, mostly oblong, bearing fine hairs on both sides. When it blooms, the inflorescences are axillary, with small pale purple flowers; after flowering it produces flat pods, and when ripe the pod wall splits open to reveal the seeds inside.

In terms of application value, the whole plant of Abrus mollis with the seeds removed can be used as medicinal material, and the medicinal name is hairy chicken-bone grass; traditionally it is considered cooling in nature and has the effect of clearing heat and draining dampness, and in the Guangdong and Guangxi areas it is often used to make soup or to blend herbal tea. However, a special reminder is needed: the seeds of plants in the genus Abrus usually contain toxic components, so before use as medicine or food the pods and seeds must be thoroughly removed to prevent accidental ingestion causing poisoning.

In recent years, in addition to wild harvesting, artificial cultivation has also been carried out in some areas to ensure the supply of medicinal material. Understanding the growth habits and contraindications of Abrus mollis helps both with identification in the wild and with safer and more reasonable use of this kind of traditional herbal medicine.
