Dragon’s Blood has been used for centuries in India as part of rituals to neutralize negative energy. It evokes Shiva and is burnt in His honour. Dragon’s Blood is cleansing and is added in small amounts to the classic frankincense mixture used in churches. A pinch of dragon’s blood increases the potency and effectiveness of other herbs in an incense mixture. Dragon's blood is a bright red resin that is obtained from different species of a number of distinct plant genera: Croton, Dracaena, Daemonorops, Calamus rotang and Pterocarpus. The red resin was used in ancient times as varnish, medicine, incense, and dye. It continues to be employed for the aforementioned purposes by some.
