In Zebrafish embryos and larva, the therapeutic applications of <em>P.tinctorum </em>widely reported. However the teratogenic effects not&nbsp; reported. This study was aimed to examine the toxicity of&nbsp;<em>P.tinctorum</em>&nbsp;on the promising model for toxicity research, the Zebrafish, because their genetic structure is more similar to human beings. Additionally, we have demonstrated a toxic effect of <em>P.tinctorum</em> extract on the human normal cell line (HEK293T) by MTT assay. The methanol extract of&nbsp;<em>P.tinctorum</em>&nbsp;was extracted by Soxhlet and for embryotoxicity and teratogenicity activities, we use different concentrations (50µg/ml – 200µg/ml) of lichen extracts on twelve selected fertilized Zebrafish embryos. The extract did not exhibit any effect on Zebrafish Survival rate, hatching rate, heartbeat and teratogenicity which was similar to control groups. To conclude that, methanol extract of <em>P.tinctorum</em> is found to have a nontoxic property to zebrafish embryo and human normal cell line (HEK293T) and suggests that this might be safe for consumption.</p>}, number={2}, journal={International Journal of Modern Agriculture}, author={M.
