I have got LD50 value for my plant is 5.18 gm/kg BW. Then, what would be the correct dose to use orally for the further study. My research area is diabetes using Wistar rats as the animal model.
I think the LD50 value for your plant is too high. Acute toxicity studies should have been done. You should consider administering 2000 mg/kg p.o. and if no mortality is observed, then select a 1/10th, 1/20th and 1/40th dose for your experiments. This will also be in accordance with the OECD guidelines.
