Zagan Vine
Zaganzâr also known as Zagána, Hendësangwa and Henhaew was a bluish oil extracted from the roots of the Zagân, a columbine relative native to cool, temperate mountains, found most frequently near, but not actually in, clearings. Zaganzâr was extracted from Zagân roots by boiling them in vinegar, filtering the extract, then adding soda, lye, or some other base to separate the oil, which floated to the surface where it was collected and filtered again. Zaganzăr caused permanent blindness by reducing the victim's optic nerves to water.
