Uses

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.[3] Where it is used to treat stomach, digestive, and gastrointestinal disorders during pregnancy.[4]

The species' extract, which contains isorhamnetin, luteolin, and quercetin, is used to fight herpes.[5] A. satureioides extract might have antiviral effects against the Western equine encephalitis virus. The extract could also have immunomodulatory properties. In general, it can help with management of viral respiratory infections, including SARS‐COV2 also known as Covid.[6]

A. satureioides could also have effects on rat pregnancy. The rats had reduced delivery index and neonatal survival after being supplemented with Achyrocline satureioides. This also has an impact on variations in tissue-specific redox homeostasis and enzymatic activity, especially in the liver and kidney.[4]

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. [7]

The plant, or sometimes just the flowers, are used to make tea. The heads of the flowers are used to make medicinal wines and bitters. The flowers are also crushed up and put in a pillow to help sleep.[8]
