Tanacetum coccineum
Caucasian daisy; natural pyrethrin insecticide source; topical use for lice and scabies.
Tanacetum coccineum, known as Caucasian daisy, is a perennial herb whose flowers yield natural pyrethrins, potent insecticides used topically for head lice and scabies. Its primary active compounds include pyrethrin I and II, along with cinerins, which act on insect nervous systems. Despite its efficacy, the plant is toxic if ingested and may cause skin irritation or allergic reactions in sensitive individuals.
Pyrethrins exert insecticidal effects by binding to voltage-gated sodium channels in insect nerve cells, prolonging their open state and causing repetitive firing, paralysis, and death. They also inhibit GABA-gated chloride channels, enhancing neurotoxicity. In mammals, rapid metabolism by esterases and cytochrome P450 enzymes limits systemic toxicity, but topical application can still trigger local allergic responses via histamine release and contact dermatitis pathways.
