Large-Leaved Linden (Tilia platyphyllos), commonly known as linden or lime tree, has a long history of use in European traditional medicine for its calming and sedative properties. Herbalists have used linden flowers in teas and infusions to alleviate stress, anxiety, and mild insomnia. Historical texts and ethnobotanical records document linden flower tea as a folk remedy to "soothe the nerves" and promote relaxation, especially in Central and Eastern Europe.

The use is primarily justified by tradition, as there are few well-designed clinical trials evaluating linden’s efficacy for stress in humans. Some phytochemical studies indicate that linden flowers contain flavonoids, volatile oils, and mucilaginous compounds, which may have mild sedative and anxiolytic effects in animal models. However, these findings have not been robustly translated into clear clinical recommendations. A handful of small, low-quality studies and case reports suggest possible benefits for nervous tension, but these are not sufficient to establish scientific validation.

In summary, the use of Large-Leaved Linden for supporting stress is rooted in traditional herbal medicine rather than strong scientific evidence. More rigorous clinical research would be needed to confirm its effectiveness and clarify its mechanism of action.
