Dragon’s blood (Dracaena cinnabari), of the Asparagaceae family. The dragon tree — a stout dichotomously branched monocot with a dense upturned-umbrella crown of stiff sword-shaped leaves, standing alone on bare limestone; native range: endemic to the limestone plateaux of Socotra, and found wild nowhere else. Globally recognized as damm-ul-akhwain (the blood of the two brothers) · dam al-akhawain in Arabic, damm-ul-akhwain · khoon-e-siyawashan in Urdu, khun-i-siyavushan in Persian, and dragon's blood, Socotran dragon's blood, cinnabar resin in English. The part used is resin, exuded from wounds in the bark. Dark red-brown brittle tears and lumps, dull outside and glassy in the fresh break; it powders to a bright blood-red and stains the fingers; almost tasteless, faintly astringent, without smell.
