Abstract
Curcuma amada Roxb. (Zingiberaceae) is known in English as mango ginger and in Bengali as amada or aam holud. The plant is native to India and can be found in the wild in both parts of Bengal, namely East Bengal (currently a sovereign country known as Bangladesh) and in West Bengal (a part of India). Crude aqueous-methanol extract of rhizomes of the plant has been shown to demonstrate hypoglycemic and antihyperglycemic activities in normal and alloxan-induced diabetic mice. Fresh inflorescence of the plant is smelled and rubbed on the head as treatment for headache by the Garasia tribe of Sirohi district in Rajasthan, India. The rhizome is used to treat amebic dysentery by the Rajbonshi tribe of Coochbehar district, West Bengal, India. Rhizome powder is used for treatment of diarrhea by tribals of Majhgawan Block of district Satna, Madhya Pradesh, India. There is a previous report of use of this plant in bone fractures in Bangladesh. In this ethno-note, we describe the use of rhizomes by a folk medicinal practitioner (FMP) from Naogaon district, to lower blood glucose in diabetic patients.
