Abstract
|
|
|
|
Platycodon (Platycodon grandiflorum) is used as a food and medicinal ingredient worldwide, particularly in Northeast Asia. Although a large number of studies have been conducted to determine its medicinal efficacy, there is still a paucity of literature summarizing the clinical activity of Platycodon. In this systematic review, we aimed to summarize the clinical efficacy of Platycodon. All literature describing the clinical efficacy of Platycodon was collected from international databases, and relevant papers were carefully evaluated for eligibility. Data were extracted from the selected papers and quality evaluation was conducted in accordance with the standards provided by the National Institutes of Health (NIH), with all procedures being conducted in accordance with PRISMA 2009 checklist guidelines. After the removal of 342 papers, 644 studies were fully screened for their titles and abstracts, among which, 19 studies were finally selected for full summarization. Extraction of data indicated evidence of the effectiveness of Platycodon in the treatment of respiratory system-related diseases and cancer, and in the provision of immunity. However, we found that the quality and objectivity of evaluation, management of variable factors, sample size, and reproducibility were generally poor. Although Platycodon has shown potential antiviral, antibacterial, anticancer, and antidepressant effects, and promotion of immunity in clinical settings, it was not possible to integrate objective indicators to conduct a meta-analysis due to the lack of literature and insufficient studies. More investigations in the clinical setting should be conducted to confirm the functional effects of Platycodon.
