"Chaste Tree" (Vitex agnus-castus) is a deciduous shrub native to the Mediterranean and parts of Asia, recognized for its violet flowers and aromatic fruit. It incorporates flavonoids, iridoids, and diterpenes that engage with biochemical pathways involved in endocrine balance. These active compounds influence neurotransmitter signaling and enzymatic activity linked to reproductive physiology. Chaste tree also contributes to hormonal feedback mechanisms that regulate systemic adaptation. Traditionally valued in herbal practices, it remains a foundational element in plant-based wellness traditions.
