Dragon's blood (DB) refers mainly to the crimson resin of many Dracaena spp. DB has been used by different traditional medicine systems worldwide, including Arabic medicine, African medicine, traditional Chinese medicine, Thai medicine, etc. DB are mainly used to heal wounds, kill pain, stop bleeding, and cure various diseases such as diarrhea, dysentery and ulcers for over 1000 years. 11 Dracaena spp. and 3 subspecies are reported to be able to produce red resin. However, the resources are extremely deficient. Several Dracaena spp. are in threatened status. Over 300 compounds have been isolated from Dracaena spp., mainly including flavonoids, steroids, and phenolics. DB exhibits anti-inflammatory, analgesic, antithrombotic, anti-oxidant, antimicrobial, antidiabetic, and anticancer properties, which explain its wound healing effects, preventive effects on cardiovascular and cerebrovascular diseases, dual-directional regulation of blood flow, neuroprotection and radioprotective effects. No apparent side effects or toxicity have been reported. DB are restricted from being exploited due to limited resources and unclear resin formation mechanism. It is necessary to expand the cultivation of Dracaena spp. and fully understand the mechanism underlying the resin formation process to develop an effective induction method for the sustainable utilization of DB.
