Background: Ziwan Baibu Tang (ZBT) is used as a traditional Chinese prescription used in the clinic to cure a variety of respiratory
diseases. The objective of this study was to evaluate the acute and subacute toxicity of ZBT.
Materials and Methods: Fifty Kunming mice were assigned to 5 groups, and ZBT was administered at different concentrations.
Symptoms, mortality and behavioural changes were recorded. Eighty Wistar rats were randomly allocated to 4 treatment groups or a
control group for 4 weeks of treatment (half male and half female); general observations and weekly body weight (BW) gain were
recorded. At the end of the 4-week experiment, the rats were sacrificed, and blood was collected for haematological and serum
biochemical analyses. Samples from the primary organs were fixed in 10% buffered formalin for histopathological studies.
Results: The calculated LD50 of acute oral toxicity was 319.16 g/kg BW. After the 4-week treatment, BW did not significantly differ
in any of the dose groups, compared with the control group (P>0.05), and the rat blood red blood cell (RBC) and haemoglobin (HGB)
levels in each dose group did not significantly differ (P>0.05). In addition, serum urea and creatine levels in each dose group did not
significantly differ from those in the control group (P>0.05).
Conclusion: These results indicate that ZBT does not possess toxic potential and that both the acute and subchronic toxicity in
animals are very low.
