About

Calamus draco is an Asian species of rattan plant in the family Arecaceae; its native range is from peninsular Thailand to western Malesia. It is a source of the red resin known as dragon's blood, which is a pigment with medicinal uses. The compound 4'-demethyl-3,9-dihydroeucomine (DMDHE), derived from the resin of Daemonorops draco, the homotypic synonym for Calamus draco, is a natural bitter-masking substance. This compound, which masks the bitter taste, suggests the importance for the food, beverage, and pharmaceutical industries to improve the taste and acceptability of foods and medicines.
