Vollista's Tourniquet (Classic Journeys Era)

Grown on Vollista, this leaf comes from a ground-based plant which somehow remains green despite growing in caves. It holds this quality chiefly through an innate ability to convert the ultraviolet portions of Vollistan auras into sustenance. It has a number of beneficial effects, including the nigh-instantaneous clotting of most lacerations, cuts, and even bullet wounds, along with disinfectant and speeding of healing properties.

The broad leaves are removed and used as first aid on Vollista, and possibly by doctors on other planets who have witnessed the effectiveness of the herb. It is sometimes restricted on planets whose medical establishments are leery of "crackpot herb-pushing doctors", but is a quite harmless remedy, and in some cases preferred over more traditional bandages.
