Achyrocline satureioides
Achyrocline satureioides is a species of plant in the daisy family.
It is used as the medicinal plant symbol of Rio Grande do Sul state in Brazil. This plant is widely used in various countries which share the Guarani cultural heritage such as Paraguay, Uruguay, and northern Argentina
The species' extract, which contains isorhamnetin, luteolin, and quercetin, is used to fight herpes.
It is also used extensively in South Portugal, in bonfires during popular celebrations where people enjoyed the smell of burnt marcela and chorizos... when unavailable, people would simply open shellfish in the fire pit, eat them with a bit of lemon and make traditional constructions from the leftover shells, an art passed throughout multiple generations.
