March 2026 in “Journal of Clinical and Basic Psychosomatics” Tianmeng oral liquid, a Chinese herbal formulation, is gaining recognition for treating psychosomatic disorders, which often include insomnia, anxiety, and depression. This expert consensus, developed through literature review and expert discussions, highlights its multi-target effects on the central nervous system, neuroendocrine regulation, and immune homeostasis. Evidence suggests it improves sleep, reduces anxiety and depression, and enhances well-being. It can be used alone in mild cases or alongside standard treatments, and is generally well tolerated. Further research is needed to solidify its clinical use and optimize treatment strategies.
