Tunkin is a smooth, climbing vine. Stems are rough, with small tuberculous outgrowths or prickles. Leaves are smooth, soft, heart-shaped, 5 to 10 centimeters long, and tapering abruptly into a narrow point at the tip.

• Glycoside Muricatin / Pharmacologic Activities: Seeds yielded a glycoside muricatin which showed to be a cardiac depressant, spasmolytic to the smooth musculature of the gut, and blood pressure lowering on the anesthetized dog.
• Seed Alkaloids: Study of seeds yielded five nitrogen indene alkaloids: ipalbidine, ipalbidinium, ipaldinium, isolpomine and ipomine.
