Acute toxicity
The acute toxicity study was conducted as per
the OECD guidelines 425, w
here the limit test
dose of 5000 mg/kg was used. No treatment
-
related mortality was observed at 5000 mg/kg.
Throughout 14 days of observation, there were
no significant (
p
>0.05) changes recorded in
behavior in any of the animals such as apathy,
hyperactivi
ty, morbidity, etc. No abnormal
changes attributable to treatment were noticed in
body weights and treatment
-
related changes like
respiration rate and heart
rate. Therefore, the extract seems to be safe at a
dose level of 5000 mg/kg, and the LD
50
is
consi
dered be > 5000 mg/kg.
There were no
clinical signs of toxicity or treatment
-
related
mortality during the observation period among
the rats. The animals appeared very healthy and
their physical activity appeared normal.
