rats (albino, adult) pyrogallol and carrageenin, purity n.p. 25 mg/kg (0.20 mmol/kg) pyrogallol i.p. 30 min. before carrageenin (0.05 mL of a 1% suspension) injection Pyrogallol significantly inhibited carrageenin-induced edema.  Bhalla et al. (1970)
lymphocyte cultures from dissociated mouse splenic cells incubated with sheep red blood cells for 4-5 days pyrogallol, purity n.p. 5 µg/culture (0.04 µmol/culture) Treatment suppressed plaque formation by >90%. The Mishell-Dutton system was used.

The author stated that the immunosuppressive effect was not due to overt toxicity.
