Paige. I would try to dissuade him from trying it. There are safer methods of inducing polyploidy using other chemicals. Colchicine can be absorbed through the skin and is very toxic. Also once in the body, there is no antidote for it. It is used in extremely small concentrations (dosages) for the treatment of gout and is probably available in Turkey by Rx at a university hospital. I would strongly dissuade him unless he has some experience in handling toxic substances or laboratory experience with dangerous chemicals. Regards, Adam Fikso
