Official title
Interactive Omics: Black Raspberry Metabolites and the Oral Microbiome in Smokers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This randomized clinical trial studies the effects of black raspberry compounds (phytochemicals) on the bacteria in the mouth (oral microbiome) of current smokers and non-smokers. The oral microbiome protects the body from pathogenic bacteria. Smoking alters the oral microbiome and may increase the susceptibility to cancer by modulating normal host-bacteria interactions. Black raspberry phytochemicals may protect the oral microbiome of smokers and may lower their risk of developing oral cancer.
