Shampoo ginger

Shampoo ginger

Zingiber zerumbet (Zingimberaceae)


Perennial herb, leafy stem up to 1.2 m tall. From autumn until spring it goes dormant above ground as the leafy stems shrivel and die away, leaving the pale brown rhizomes at ground level. In the spring, the plant springs up anew. 10-12 blade-shaped leaves, 15-20 cm long, alternate. Among the leafy stems, the conical flower heads burst forth on separate and shorter stalks. These appear in the summer, after the stem has been growing for a while. The flower heads are initially green, 3-10 cm, with overlapping scales, enclosing small yellowish-white flowers that poke out a few at a time. As the flower heads mature, they gradually fill with an aromatic, slimy liquid and turn a brighter red color.


Native to tropical Asia and Australasia but can be found in many tropical countries. The earliest evidence of its cultivation is from the Austronesian people who carried it with them during the Austronesian expansion (ca. 5000 BP) as canoe plants, reaching as far as Remote Oceania.

Natural Medical Properties

A decoction is used as a carminative to treat colic.
