There are, however, one major mistake, and this is a mistake that is not uncommon. The common name centaury is used for several unrelated plant genera, most commonly Centaurium (a gentian, in Gentianaceae), and Centaurea in the sunflower and aster family (Asteraceae).
The plant listed as "Centaury (Centaurium Erythraea)", should be Centaurium erythraea, but the photo at Weleda's website is of Centaurea cyanus, so the two genera are also mixed up. It is simply the wrong species photo with the bitter-tasting Centaurium plant they use in their products.

The species epithet should be listed with a lower case letter in the beginning, as 'erythraea'. Weleda gets this formatting rule wrong for most of its plant species names, but that is easy to fix. For example, 'Arnica Montana' should be 'Arnica montana' in the ingredient list to be accurate.
Common names that are the same for several unrelated species are not at all unusual; examples are snakeroot, hemlock, sycamore, and ironweed. One species can have several common names too, so common names can be very confusing. Only scientific names are unique to a species and universal and the same worldwide. But more on that in a later post.
