 obtained from a number of different plants. It was held by early Greeks, Romans, and Arabs to have medicinal properties; Dioscorides and other early writers described it. A chief source was Dracaena cinnabari, a tree of the agave family. Voyagers to the Canary Islands in the 15th cent. obtained it from another species, D. draco. The resin, exuding beautiful garnet-colored drops when the tree is wounded, was well known as the source of varnish for 18th-century Italian violinmakers. Later, dragon's-blood varnishes and medicines were obtained chiefly from the immature fruits of a palm (Daemonorops draco) native to Malaya. Although still sometimes used in photoengraving processes, dragon's blood as a coloring material has largely been replaced by synthetics.

Dragon's Blood

(religion, spiritualism, and occult)

Daemonorops draco, a red resin obtained from one of the rattan palms of Indonesia. The fruit of the palm is round, pointed, scaly, and the size of a large cherry. When ripe, the fruit exudes a resin known as dragon's blood. In brittle, shell-like flakes, this can be ground into a fine red powder.

Dragon's blood was once prized as a medicine in Europe because of its astringent properties.

Folklore has it that dragon's blood is useful in love magic and for protection, as well as for exorcisms. Scott Cunningham says that a stick of dragon's blood under the mattress will cure impotency, and when mixed with sugar and salt and stored in a bottle will guarantee peace and quiet in the house where it is kept. Many Witches and magicians use dragon's blood to make an ink used for constructing talismans and magical squares.

Siegfried, from the heroic literature of the ancient Teutons, was made invulnerable by taking a bath in dragon's blood. Such a bath is also said to restore the petrified to life. In Danish folklore, only the blood from the heart of a dragon can restore an imperiled king. These folk tales, however, refer to the actual blood of a dragon.
