Dragon's Blood
The Dragon's Blood of commerce is resin used in medicine as a colouring agent, and in plasters and tooth-powders. It is furnished by Calamus Draco, and is imported into this country from Eastern Sumatra, Southern Borneo, &c. The resin covers the scales of the fruit with a thin coat, and is obtained by shaking the fruits or beating them in a sack, then melting in the sun or in boiling water, and afterwards moulding into lumps, balls, or sticks. The name Dragon's Blood is also given to resins yielded by Dracoena Draco in the Canary Islands, by Dracoena cinnabarina in Socotra, and also by Pterocarpus Draco.
