Cultural notes are presented as tradition and historical context, attributed to where they come from.
Amazonian Indigenous (Peru/Ecuador) · Pre-Columbian – present
Sangre de grado wound sealant
Indigenous peoples of the upper Amazon, including the Shuar and Quechua, have long scored the bark of Croton lechleri to collect its dark red latex, called sangre de grado (blood of the dragon). Applied directly to cuts, insect bites, and skin ulcers, the latex forms a protective seal and promotes rapid healing, a practice documented by colonial-era naturalists and modern ethnobotanists alike.
Roman · 1st century CE
Cinnabari in Pliny and Dioscorides
Pliny the Elder and Dioscorides both described a red resin they called cinnabari, sourced from Dracaena species on the island of Socotra. Used in Roman medicine as a styptic to stop bleeding and as a wound plaster ingredient, this dragon's blood resin was also employed as a pigment and varnish across the empire.
Yemeni (Socotra Island) · Ancient – present
Socotran Dracaena harvest tradition
On the island of Socotra off the coast of Yemen, inhabitants have harvested red resin from Dracaena cinnabari trees for millennia. The resin was a major trade commodity shipped to ancient Egypt, Greece, and Rome. Socotran communities still collect it traditionally for use as medicine, dye, and incense, and the dragon's blood tree remains the island's iconic species.
Chinese · 5th–6th century CE (Southern and Northern Dynasties)
Xue jie in Chinese trauma medicine
Dragon's blood resin from Daemonorops draco palms entered Chinese materia medica as xue jie (blood exhaustion), valued for invigorating blood circulation, stopping bleeding, and healing wounds. The physician Tao Hongjing included it in his 'Collected Commentaries on the Materia Medica,' and it became a standard ingredient in trauma plasters and pills.
European Renaissance · 15th–17th century CE
Italian violin varnish and alchemical use
Renaissance Italian luthiers, including those in Cremona, used dragon's blood resin as a red tinting agent in instrument varnishes. Simultaneously, European alchemists prized the resin in ritual magic and medicinal preparations, believing its resemblance to blood gave it sympathetic healing power over hemorrhage and internal wounds.
