Phytochemical Strategies for Schizophrenia Management: Bridging Traditional Remedies with Modern Psychiatry

Schizophrenia (SZ), a chronic psychiatric disorder, presents significant challenges in its management, primarily due to its complex etiology and the limitations of current antipsychotic therapies. Traditional antipsychotics often alleviate positive symptoms but exhibit limited efficacy for negative and cognitive symptoms, alongside notable adverse effects. This has led to an increasing exploration of herbal remedies as complementary or alternative approaches. The review highlights the function of medicinal plants and phytochemicals in SZ management. The highlighted neuroprotective, antioxidant, anti-inflammatory, and receptor-modulating characteristics of plant-based compounds, such as alkaloids, glycosides, terpenes, and polyphenols, target critical neurotransmitter systems, including dopaminergic, serotonergic, and GABAergic pathways. Key examples, such as Mitragyna speciosa, Withania somnifera, and Ginkgo biloba, demonstrate the potential to mitigate SZ symptoms through mechanisms like oxidative stress reduction and receptor modulation. Furthermore, the synergistic effects of these herbs, when used as polyherbal formulations, as exemplified by traditional remedies like Yokukansan and Suoquan pill, underscore the therapeutic potential of combining multiple herbs. While promising, challenges remain in standardizing herbal preparations and validating their efficacy through rigorous clinical trials. The review consolidates the current understanding of phytoconstituents and herbal formulations, advocating for their potential integration into mainstream psychiatric care.
