Abstract
Objective
A systematic review and meta-analysis was carried out to verify evidence regarding the efficacy and safety of the clinical applicability of natural products in the prevention and treatment of oral mucositis induced by chemotherapy and/or radiotherapy.
Methodology
An electronic research according to the PICOS strategy, using the terms “natural products” and “oral mucositis,” was carried out at Pubmed, Cochrane, Embase, and “gray literature.” The stages of eligibility, data extraction, and quality assessment of the studies were carried out independently and in duplicate.
Results
The number of studies identified as eligible was 151, including 47 randomized controlled trials, reporting a total of 3075 participants undergoing some therapy with natural products on oral mucositis. The included clinical trials covered a variety of 31 types of natural products. Considering the risk of bias of the clinical trials, 24 studies (51.1%) were considered to have a low overall risk of bias, nine (19.1%) were at moderate risk, and 14 clinical trials (29.8%) were at high risk of bias. Honey was the most assessed natural agent. Fourteen studies (3.4%) reported that natural agents reduced pain.
Conclusion
The results of the meta-analysis support a positive effect of honey and Aloe vera in reducing mucositis in patients receiving cancer therapy.
Clinical relevance
The results found add relevant information to the scientific community regarding the prevention and treatment of mucositis.
