Studies on the anti-tumour, anti-bacterial, and wound-healing properties of dragon's blood

Planta Med. 1994 Dec;60(6):541-5. doi: 10.1055/s-2006-959567.


Three in-vitro assays have been adopted to examine the cytotoxicity and anti-bacterial activity of the blood-red sap of Croton lechleri from Ecuador, and to examine its effect upon the proliferation of endothelial cells. The sap was found not to be cytotoxic. Several simple phenolic compounds and diterpenes showed a potent anti-bacterial activity. The sap has little effect upon the proliferation of endothelial cells, and no single active ingredient was identified. A mechanism for the wound-healing property of the sap has been proposed.
