Journal of integrative medicine July 1, 2023 Biao Gao, Yi-Cui Qu, Meng-Yu Cai et al. 9 citations
Research on plant-based treatments for post-traumatic stress disorder has surged since 2015, with nearly half of all relevant articles coming from North America. A cluster co-occurrence network analysis of 301 articles from the Web of Science database (2007–2022) shows the field is dominated by neuroscience and neurology, and most studies focus on psychedelic interventions. Three timelines reveal an "ebb and flow" between research on substance use/marijuana abuse and psychedelic medicine/medicinal cannabis. Other phytochemicals account for a small proportion of studies, examining neurosteroid turnover, serotonin levels, and brain-derived neurotrophic factor expression. The research is unevenly distributed across countries, disciplines, and journals.
