毒性The six insecticidal constituents of the extract of the pyrethrum flowers Pyrethrum (Chrysanthemum cinerariaefolium). Pyrethrins I and II are most prominent, existing in the ratio 71:21:7 for pyrethrin (I and II), cinerin (I and II), jasmolin (I and II). Pyrethrins are potent, nonsystemic, contact insec_x0002_ticides, causing rapid paralysis or knockdown and death at a later stage in a variety of insects. They exhibit low vertebrate toxicity with an acute oral LD50 in rats of 1.2 g/kg. The mechanism of action involves modification of nerve membrane Na1 channels. Opening and closing of the Na1 channel is slowed, resulting in increased Na1 permeability and depolarization leading to hyperexcitability. Symptoms in humans include gastrointestinal irritation, nausea, vomiting, diarrhea, numbness of tongue and lips, syncope, hyperexcitability, incoordination, convulsions, muscular paralysis, collapse and death due to respiratory paralysis. Treatment involves gastric lavage, emetics, cathartics, demulcents, artificial respiration if necessary and short-acting barbiturates for convulsions.
