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 color 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 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.
