It is pity that to save people poisoned with Ricin practically is impossible because of the absence of proper antidote to Ricin. Unfortunately, lectin – Ricin especially dangerous is for children, as beautiful leaves and fruit of this plant are very attractive for them. They make beads from its fruit and wear them around their necks. Based on the above-said, at detection of castor plant, it should be immediately timely uprooted and destroyed to avoid a danger of the spread of this deadly beautiful plant in the places available for the children. It is pity that several cases of the poisoning with this plant have already been recorded.
