- Executive summary:
In an acute oral toxicity study (limit test), ten rats were given 2050, 2560, 3200 and 5000 mg/kg bw/day and 5 rats were given 1050 and 1640 mg/kg bw/day of Myrrh oil . Animals were observed for mortality and clinical signs for 14 days.
10 mortality on 10 animals observed at 5000 mg/kg bw
10 mortality on 10 animals observed at 3200 mg/kg bw
8 mortality on 10 animals observed at 2560 mg/kg bw
9 mortality on 10 animals observed at 2050 mg/kg bw
2 mortality on 5 animals observed at 1640 mg/kg bw
1 mortality on 5 animals observed at 1050 mg/kg bw
In this study, the oral LD50 is 1650 mg/kg bw in rats.
Under the experimental conditions of this study, the test substance is classified Acute tox 4 (H302) according to Regulation (EC) No. 1272/2008 (CLP) and to GHS
