Objectives: To analyse the quality of abstracts of the randomized controlled clinical trials on Curcuma longa L. Materials and methods: The research assessed the quality of the abstracts of randomized controlled trials available in the MEDLINE database using the PubMed search engine with the keyword search „Curcuma longa“ and the option „randomized controlled trial“. The abstracts were then evaluated according to the criteria from the CONSORT list. The obtained data were then analysed and interpreted using the statistical analysis program MedCalc. Results: The search resulted in 170 scientific articles, among which 138 articles met the inclusion criteria for the research. The median of the total sum of the abstract was 7 with an interquartile range of 6-9. Significant differences were found regarding the presence of CONSORT items depending on the abstract structure. CONSORT items that appeared with the highest frequency were objective and primary outcomes. CONSORT items that appeared with the lowest frequency were the source of funding and randomization process. Conclusion: Abstracts of scientific research with the Curcuma longa L. are of low to moderate quality according to the criteria of the CONSORT list. A worrying fact is that there is a lack of information of founding source and randomization process in most of the abstracts, which significantly impact transparency and trustworthy of the clinical trials.
