Dragon's blood was used as a dye, painting pigment, and medicine (respiratory and gastrointestinal problems) in the Mediterranean basin, and was held by early Greeks, Romans, and Arabs to have medicinal properties.
Locals on Socotra island use the Dracaena resin as a sort of cure-all, using it for such things as general wound healing, a coagulant (though this is ill-advised with commercial products, as the Daemonorops species acts as an anti-coagulant and it is usually unknown what species the dragon's blood came from), curing diarrhea, lowering fevers, dysentery diseases, taken internally for ulcers in the mouth, throat, intestines and stomach, as well as an antiviral for respiratory viruses, stomach viruses and for skin disorders such as eczema. It was also used in medieval ritual magic and alchemy.
Dragon's blood of both Dracaena draco (commonly referred to as the Draconis Palm) and Dracaena cinnabari were used as a source of varnish for 18th century Italian violinmakers. There was also an 18th-century recipe for toothpaste that contained dragon's blood. In modern times it is still used as a varnish for violins, in photoengraving, as an incense resin, and as a body oil.
Dragon's blood from both Daemonorops were used for ceremonies in India. Sometimes Dracaena resin, but more often Daemonorops resin, was used in China as red varnish for wooden furniture. It was also used to colour the surface of writing paper for banners and posters, used especially for weddings and for Chinese New Year.
In American Hoodoo, African-American folk magic, and New Orleans voodoo, it is used in mojo hands for money-drawing or love-drawing, and is used as incense to cleanse a space of negative entities or influences. It is also added to red ink to make "Dragon's Blood Ink", which is used to inscribe magical seals and talismans.
In folk medicine, dragon's blood is used externally as a wash to promote healing of wounds and to stop bleeding. It is used internally for chest pains, post-partum bleeding, internal traumas and menstrual irregularities.
In neopagan Witchcraft, it is used to increase the potency of spells for protection, love, banishing and sexuality. In New Age shamanism it is used in ceremonies in a similar way as the neopagans use it.
Dragon's blood incense is also occasionally sold as "red rock opium" to unsuspecting would-be drug buyers. It actually contains no opiates, and has only slight psychoactive effects, if any at all.
Thaspine from the Dragon's Blood of the species Croton lechleri has possible use as a cancer drug.
