Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Proprietary blends containing herbs and botanicals have traditionally been used in various systems of medicine, such as Ayurveda and Traditional Chinese Medicine (TCM), to support relaxation, stress reduction, and overall nervous system health. Many herbal formulations are designed to calm the mind and body, which aligns with the function of the parasympathetic nervous system—promoting "rest and digest" activities. Common ingredients in such blends may include valerian root, passionflower, ashwagandha, lemon balm, and others. While there is some scientific interest in individual herbs for their anxiolytic (anxiety-reducing) and sedative effects, the evidence supporting the efficacy of proprietary blends as a whole is limited and often confounded by variability in formulation, dosage, and ingredient quality. Most studies have focused on single herbs rather than combinations, and results are mixed regarding their direct impact on the parasympathetic nervous system, as measured by physiological markers such as heart rate variability or cortisol levels. Overall, the use of proprietary herbal blends to support the parasympathetic nervous system is primarily justified by traditional usage rather than robust clinical evidence. Individual components may have some supporting data, but the combined effect and mechanism remain insufficiently studied. Consumers should exercise caution and consult healthcare professionals before using such blends for nervous system support.
