Exposure to pyrethrum, the crude form of pyrethrin, [31] causes harmful health effects for mammals. Pyrethrum also has an allergenic effect that commercial pyrethroids don't have. [ 31 ] In mammals, toxic exposure to pyrethrum can lead to tongue and lip numbness, drooling , lethargy , muscle tremors , respiratory failure , vomiting , diarrhea ...
[1] In household concentrations pyrethroids are generally harmless to humans. [1] However, pyrethroids are toxic to insects such as bees, dragonflies, mayflies, gadflies, and some other invertebrates, including those that constitute the base of aquatic and terrestrial food webs. [2] Pyrethroids are toxic to aquatic organisms, especially fish. [3]
The National Institute for Occupational Safety and Health (NIOSH) has set a Recommended exposure limit (REL) of 5 mg/m 3 over an 8-hour workday. At levels of 5000 mg/m 3, pyrethrum is immediately dangerous to life and health.
Chronic exposure to allethrins alters the plasma biochemical profile of humans and may have adverse health effects. [2] Bioallethrin has been shown to cause oxidative damage, cellular toxicity and necrosis of human lymphocytes studied in vitro. [3] It is highly toxic to fish and aquatic invertebrates.
[1] Like other pyrethroids, bifenthrin is chiral; it has different enantiomers which can have different effects. Bifenthrin is found in two enantiomers: 1S-cis-bifenthrin and 1R-cis-bifenthrin. 1S-cis-Bifenthrin is 3-4 times more toxic to humans than 1R-cis-bifenthrin, while the latter is more than 300 times more effective as a pesticide.

Cyfluthrin is a pyrethroid insecticide and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of isomers.Like most pyrethroids (MoA 3a), [1] it is highly toxic to fish and invertebrates, but it is far less toxic to humans. [2]
Now TikTokers are drinking it, claiming that a pinch of borax dissolved in water, or even mixed into a smoothie or coffee, has plenty of health benefits. The claim and how it started
Tanacetum cinerariifolium is a species of flowering plant in the aster family, Asteraceae, [1] and formerly part of the genus Pyrethrum, but now placed in the genus Chrysanthemum, or the genus Tanacetum by some biologists. It is called the Dalmatian chrysanthemum or Dalmatian pyrethrum, denoting its origin in that region of Europe (Dalmatia ...
