Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- The LD50 of Fessoukh extract with absolute ethanol in rats is 1656 mg/kg bw therefore it is classified as category 4, "H302: Harmful if swallowed" according to Regulation EC No. 1272/2008.
- Executive summary:
Six groups of 10 albino rats each (5 males and 5 females) were administrated Fessoukh extract with absolute ethanol at doses of 500, 1000, 1500, 2000, or 3000 mg/kg bw. The control group was given peanut oil only, which was used as the vehicle. All animals were observed daily for 15 days, and deaths or any other toxic effect were noted.
At 3000 mg/kg, deaths occurred within 24 h after administration. At lower doses, deaths of rats began after 4 days. Rats that survived more than 4 days had bleeding from nose, eyes, and anal and genital organs. The affected rats first had diarrhea on the 1st and 2nd day after dosing and then bleeding on days 2 and 3. The animals then had anemia and ataxia, and the last died the 7th day after dosing.
The calculated LD50 was 1656.1 mg/kg bw, with a 95% confidence limit of 1576.0 to 1740.4 mg/kg therefore the test item is classified as category 4, "H302: Harmful if swallowed" according to Regulation EC No. 1272/2008.
