Akebia quinata, commonly known as chocolate vine, five-leaf chocolate vine, or five-leaf akebia, is a shrub that is native to Japan, China and Korea, and invasive in the eastern United States from Georgia to Michigan to Massachusetts. In its native habitat, it is often found on hills, in hedges, on trees, along forest edges and streams, and on mountainous slopes. 

The fruit contains a sweet soft pulp resembling a white dragonfruit, eaten primarily in Japan as a seasonal delicacy. The rind, with a slight bitter taste, is used as vegetable, e.g., stuffed with ground meat and deep-fried. The vines are traditionally used for basket-weaving.

The stem contains approximately 30% potassium salts thus causing a diuretic action.

Akebia Quinata Extract is the extract of the whole plant, Akebia quinata, Lardizabalaceae.
