Conium maculatum the difficulty in associating malformations with the much earlier maternal poisoning. Since no specific antidote is available, prevention is the only way to deal with the production losses caused by the plant. Control with herbicides and grazing with less-susceptible animals (such as sheep) have been suggested. "C. maculatum" alkaloids can enter the human food chain via milk and fowl. "Conium maculatum" is the plant that killed Theramenes, Socrates and Phocion. In ancient Greece, hemlock was used to poison condemned prisoners. Socrates, the most famous victim of hemlock poisoning, was accused of impiety and corrupting the young men of Athens in

Like many of the genus "Hyloxalus", "H. subpunctatus" possesses fairly weak toxins, compared to those of other dendrobatids. It may be one of the most primitive of dendrobatids, as it has only begun to develop skin alkaloids and is still fairly drab in coloration. Its poison is already an effective defense mechanism; if tasted by a predator, the alkaloids in the frog's skin cause extreme pain and unpleasant taste. This will usually discourage a predator from attacking a cream-backed poison frog more than once. However,
