Crawford (2015) gave a very elaborate record of the ethnic uses of cetrarioid lichens, including Cetraria islandica, Cetrelia pseudolivetorum, Flavocetraria cucullata, Flavocetraria nivalis, Masonhalea richardsonii, Nephromopsis pallescens, Vulpicida canadensis, Vulpicida juniperinus and Vulpicida pinastri.
One example is the study of Cetraria islandica complex: by a careful examination of over 3000 specimens, Kristinsson (1969) found that this group contained both fumarprotocetraric acid-producing and -deficient variants revealed by p-phenylenediamine spot testing, and that such chemotypes had no correlations with morphology and geography.

The extracts had a high total phenolic content, and the main constituents identified by HPLC were fumarprotocetraric acid in Cetraria islandica, and usnic, pinastric and vulpinic acids in Vulpicida canadensis.
The present work focuses for the first time on the possible neuroprotective and anticancer properties of the methanol extracts from two Parmeliaceae lichens from the cetraroid clade: Cetraria islandica and Vulpicida canadensis.

In traditional medicine some lichen species such as Iceland moss, Cetraria islandica, have been widely used for treating inflammatory conditions such as asthma and gastritis, as well as tuberculosis, without being associated with any adverse effects.
