Quick Summary

Rotenone is a crystalline insecticide derived from the roots of tropical plants, such as derris. It is highly toxic to fish but has low toxicity to warm-blooded animals. Rotenone is used as an insecticide, particularly in home gardens. It can cause irritation to the skin, eyes, and lungs, and may cause mild central nervous system stimulation. In rats, it has been identified as a carcinogen. Rotenoids are compounds chemically related to rotenone and often occur alongside it.123
