Hepatotoxin
A hepatotoxin ( Gr., hepato = liver) is a toxic chemical substance that damages the liver.
It can be a side-effect of medication, or found naturally, as microcystins, or in laboratory environments.
The effects of hepatotoxins depend on the amount, point of entry and distribution speed of the toxin, and on the health of the person.
