use

Socrotic Dragonborn

The red-brown to brown-red dragon's blood , a natural resin, is extracted from Dracaena cinnabari . The people of Socotra use it to cure stomach ailments, to dye wool, to make glue and to decorate ceramics and their houses with it.

In the Arabian Peninsula, as well as in other countries, the dried and powdered resin is often used as a herbal remedy with analgesic , astringent , antiseptic , hemostatic and anti-ulcer properties against many diseases, and as an abortive agent during the first trimester of pregnancy.
