TAL'VAK ACID

Tal'vak acid was used by Ba'al as a means of torturing O'Neill. The acid slowly burns all the way through the body, and although it cauterizes the flesh as it burns, a very small amount often finds its way into the blood and begins to spread. An antidote can neutralize the acid and numb the pain.
