One of the most societally destablising drugs ever developed, Ascomycin is an anti-agathic, which is to say, it is a drug that prevents or retards aging.
Ascomycin is a drug that confers non-specific immunity. It’s less an anti-biotic than a true endotoxin, and works to prevent nearly any disease from affecting those dosed with it – and a single dose lasts about 70 years.
The mechanism of the drug involves stimulation of the reticulo-endothelial system (the white blood cells and such). It is apparently a biological drug with multiple sources, though generally not more than one or two to a plant. The Okie ‘Cities in Flight’ use it as part of an their immortality drug suite.
