Greek mountain tea (Sideritis spp.) has been traditionally consumed in Greece and neighboring regions for its purported health benefits, including for relaxation and emotional well-being. Folk medicine often recommends Greek mountain tea as a calming beverage, believed to soothe nerves, reduce stress, and enhance mood. However, the evidence supporting its use specifically for "emotional sensitivity"—a modern psychological term encompassing heightened emotional responses or vulnerability—is largely anecdotal and based on tradition rather than rigorous science.

Some phytochemical studies have identified antioxidant and anti-inflammatory compounds in Sideritis species, and limited preclinical research suggests possible anxiolytic (anxiety-reducing) and neuroprotective effects, possibly due to modulation of neurotransmitter systems such as GABA. A few small human studies have indicated potential for mild mood support or cognitive benefits, but these are preliminary and not directly linked to emotional sensitivity as a clinical condition. No substantial clinical trials have specifically investigated Greek mountain tea for treating or supporting emotional sensitivity.

In summary, while Greek mountain tea is traditionally used for promoting relaxation and general emotional well-being, scientific validation for its efficacy in managing or treating emotional sensitivity is currently limited. The tradition is strong, but the evidence base is weak, justifying a rating of 2.
