Detailed description

Greek mountain tea, Sideritis scardica Griseb, is an aromatic plant emblematic of the Balkan basin, notably originating in the mountainous regions of Albania, Bulgaria, Greece, Northern Macedonia and Kosovo.

Used since ancient times as an infusion, it is traditionally appreciated for its aromatic properties and its role in supporting general well-being, particularly vitality and a feeling of daily comfort.

The flowering tops of Sideritis scardica are particularly rich in natural bioactive compounds:

Phenols and polyphenols: verbascoside, chlorogenic acid, caffeic acids – (antioxidants)
Flavonoids: apigenin, hypolaetin, isoscutellarein – (antioxidants and neuroprotectors)
Phenylethanoid glycosides: lavandulifolioside, verbascoside, echinacoside
Terpenoids and iridoids: contributing to its complex aromatic profile

These compounds give the plant an aromatic richness and support for general well-being, as well as interest in dietary supplement formulations designed to promote vitality and normal cognitive function.
