BACKGROUND
The roots and root barks of Echium sp. have been used to treat ulcers, burns and wounds in traditional Turkish medicine.
OBJECTIVE
On the basis of them traditional use and literature references, four Echium species were selected for evaluation of them wound healing potential. Isolation of
