Greek mountain tea (Sideritis spp.) has a long history of traditional use in the Mediterranean, particularly in Greece, where it is brewed as an herbal infusion. Traditionally, it has been used to support general wellness, boost the immune system, and relieve symptoms of colds and respiratory issues. Its use to support the "Senses" body system—encompassing sight, hearing, taste, smell, and touch—is primarily based on folklore and anecdotal applications. There is some traditional belief that Greek mountain tea may aid with eye health, particularly in folk medicine, but this is not a prominent or universally recognized use. Scientific research on Greek mountain tea has mainly focused on its antioxidant, anti-inflammatory, and neuroprotective properties. Some preliminary studies suggest it may have neuroprotective effects, which could theoretically support cognitive function and, by extension, senses such as memory or possibly even vision. However, direct clinical evidence linking Greek mountain tea to specific improvements or protection of the senses (e.g., eyesight, hearing) is limited. In summary, while Greek mountain tea has a place in traditional medicine, its specific use for supporting the senses is not robustly validated by scientific evidence, and traditional support for this specific system is limited. Most claims remain anecdotal, warranting a moderate evidence rating.
