PYRETHRUM

Chrysanthemum cinerariaefolium

(family

Asteraceae

)

GENERAL CHARACTERISTICS

The pyrethrum, whose scientific name is Chrysanthemum cinerariaefolium (trev.) Vis., belongs to the family of Asteraceae (former Compositae). It is a plant that in Europe is found spontaneously only along the coasts of the Adriatic Sea.

It is widely cultivated (especially in Kenya and Congo, scarcely in Italy) to extract pyrethrins, very toxic for cold-blooded animals and therefore used for the preparation of insecticides.

It is a perennial plant that recalls the daisy from which it differs for its deeply engraved, velvety, greyish leaves, almost all located at the base of the stem and for the unmistakable scent.

PROPERTY'

Pyrethrum is made up of pyrethrins and its properties are parasiticidal.

USED ​​PARTS OF THE PLANT

From the pyrethrum, the freshly opened harvested flower heads are used which are dried in the shade and then ground to obtain a yellow-greenish powder called razzia or pyrethrum.

HOW TO USE IT

It is used for the preparation of insecticides for cold-blooded animals towards which it is very toxic while it is very little toxic for humans and warm-blooded animals in general as well as being low-polluting.

CURIOSITY'

Pyrethrum is currently widely used as an insecticide and is spreading more and more also in agriculture because it is not very polluting and is among the least harmful for humans and warm-blooded animals.

WARNINGS

There are no particular reports for its use.
