Exploring the antidepressant potential of Yueju Pill: Insights from traditional Chinese medicine

Depression, a complex global disorder with unmet therapeutic needs, imposes profound societal burdens. Yueju Pill (YJP), a classic TCM formula targeting 'six stagnations', synergistically integrates five herbs (Atractylodes, Cyperus, Ligusticum, Gardenia and Massa Medicata) to restore Qi-blood homeostasis. Contemporary evidence delineates its multitarget antidepressant efficacy: normalising monoaminergic neurotransmission and the tryptophan-kynurenine pathway, potentiating neurotrophic support (BDNF/eEF2) for neuroplasticity, antagonising neuroinflammation via microglial M1-to-M2 polarisation and NF-κB/MAPK inhibition, mitigating oxidative stress and mitochondrial dysfunction and enhancing synaptic plasticity through glial/neuronal gene regulation (e.g., GADD45g/PHGDH). This synthesis of TCM principles with mechanistic evidence positions YJP as a holistic, systems-level therapeutic candidate, advocating for rigorous clinical validation and integration into precision psychiatry.
