The acute, sub-acute and chronic toxicity studies on boswellic acids (
BAs) were carried out on mice, rats and monkeys. BAs did not cause any
mortality in rats and mice when administered orally and intraperitone
ally in doses up to 2 g/kg. Daily oral administration of BAs in three
doses (low and very high) to rats and monkeys revealed no significant
changes in general behaviour, or clinical, haematological, biochemical
and pathological data. BAs, therefore, can be regarded as safe for cl
inical studies.
