title: Melissa officinalis and Passiflora caerulea infusion as physiological stress decreaser.
abstract: The objective of this study was to determine the effect of a Melissa officinalis and Passiflora caerulea infusion on the severity of physiological chronic stress induced by movement restriction in CF-1 mice. 40 CF-1 male mice, six weeks of age, were divided into 4 groups (n = 10 for each group): (1) Group RS/MP received two treatments, induced stress through movement restriction and a infusion of Melissa officinalis and Passiflora caerulea in a dose of 200 mg/kg, (2) RS group with induced stress using movement restriction, (3) MP group, which received only a infusion, and (4) a CONTROL group that received no treatment. The severity of the stress was obtained by analysis of the physical parameters of body weight, thymus and spleen, and associated biomarkers with stress, corticosterone, and glucose. Animals that consumed Melissa officinalis and Passiflora caerulea infusion had lower plasma corticosterone levels (Student's t test, Welch, p = 0.05), which is the most important biomarker associated with physiological stress, demonstrating a phytotherapy effect.
