Botanical name : cucuma pseudomontana. Family Zingiberaceae (Ginger Family)
Hill tumeric is an Indian herb used in local and tribal medicine and is a source of arrowroot starch.
It is different from the ordinary yellow turmeric which we cook with and can easily be found in the markets.
According to some Indian friends, this plant can be used to cure jaundice and can treat body swellings. Boiled tubers can help women to increase lactation. The tuber past among the Khand tribes is applied on the head for cooling effect. It would be nice to be able to grow this.
However I am wondering if it is the same as what the Ibans call Entimut.
