Which poison is most lethal to humans?
<|assistant|>
The most lethal poison to humans is ricin, a toxin found in the castor beans of the plant Ricinus communis. Ricin is one of the most powerful naturally occuring poisons and can cause severe damage or death if ingested or injected in small doses. Symptoms of ricin poisoning include vomiting, convulsions, fever, and circulatory collapse. Without prompt medical attention, ricin poisoning can cause respiratory failure, pulmonary edema, and eventual death.
