Curcuma mangga Valeton & van Zijp
Curcuma amada, or mango ginger is a plant of the ginger family Zingiberaceae and is closely related to turmeric (Curcuma longa). The rhizomes are very similar to common ginger but lack its pungency, and instead have a raw mango flavour. They are used in making pickles in south India and chutneys in north India. It is served as chutney in community feasts in Nepal's southern plains. Mango ginger and elephant foot yam pickle is popular in Nepal's southern plains. The taxonomy of the species is a subject of some confusion as some authorities have considered the name C. mangga as identical while others describe it as a distinct species with C. mangga being found in southern India while C. amada is of east Indian origin.

It is a delicious addition to salads and stir fries. It is used in South Asian and Southeast Asian as well as Far East Asian cuisines.
