This mixed (qualitative and systematic) study aimed to investigate the effectiveness of lavender tea in reducing nervous tension and anxiety disorders. In the systematic review section, 45 (30 quantitative and 15 qualitative) published between 2015 and 2024 were analyzed. The results showed that daily consumption of 1.5 g of dried lavender flowers for 4 weeks reduced the GAD-7 score by an average of 34% (SMD = -0.72; p < 0.001) and increased the duration of deep sleep (NREM stage 3) by 27 minutes. Qualitatively, the participant's experiences in a 12-month longitudinal study reported five main themes: a feeling of immediate relaxation, reduced heart rate, improved sleep, 30 naturalness over chemical drugs, and enhanced self-efficacy. The mechanisms of action were assessed through the modulation of GABA-A receptors by the compounds linalool and linalyl acetate and a 22% reduction in cortisol levels. The main challenges included heterogeneity in tea preparation methods (water temperature and steeping time) and demographic differences (higher efficacy in women and Mediterranean populations). Despite the favorable safety profile (only 8% of mild adverse events), there is a need for standardization of consumption protocols and long-term studies to increase environmental sustainability. This study suggests lavender tea as a low-cost and low-complication intervention in the management of mild to moderate diabetes and calls for its integration into complementary medicine protocols, especially for vulnerable populations.
