Objective: The aim of this study is to investigate the symptomatic efficacy of oral use of different functional honeys in patients complaining of sore throat.

Materials and Methods: In the preclinical phase of the study, a total of 1000 samples of honey were examined, and the honeys were subjected to physicochemical and microbiological analyses. Based on their functional properties, five different groups of honey were determined. These are thyme honey with high antioxidant capacity, Yüksekova with high antimicrobial activity, chestnut honey with high organic acid amount, linden honey with high enzymatic and pine honey with high anti-microbial, antioxidant and phenolic compounds and enzymes. In the clinical phase of the study, patients receiving conventional treatment were randomly assigned to receive either one of five different types of honey or a honey-like food product in addition to their treatment. They were instructed to use 15 grams twice daily for 10 days. Patients were assessed on the 1st, 3rd, 7th, and 10th days for symptoms and complaints such as sore throat, difficulty swallowing, sensation of throat swelling, weakness, and fatigue.

Inclusion Criteria: Adults presenting with sore throat symptoms due to an upper respiratory infection (URI) within the last four days were included in the study. A total of 300 patients over 18 years of age, who were prescribed necessary medication and exhibited signs and symptoms of sore throat, were enrolled.

Exclusion Criteria: Exclusion criteria included a history of diabetes, pollen or bee allergies, and aversion to honey. Participants were required not to use any additional products outside of those provided by the researchers during the study period. Written informed consent was obtained from all participants, who were then randomly assigned to either the study or control group.
