Dietary Supplement: longan syrup
Registration Number
NCT04300036
Lead Sponsor
Chulalongkorn University
Brief Summary

The objectives of this study were to evaluate efficacy and safety of longan syrup in healthy volunteers with insomnia. Subjects will take 15 ml of longan syrup once a day for 3 months. They will be investigated their insomnia using Insomnia Severity Index (ISI) questionnaire, Thai- The Pittsburgh Sleep Quality Index (PSQI) questionnaire,STOP - BANG questionnaire, Epworth Sleepiness Scale (ESS) questionnaire, Actiwatch, plasma cortisol, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), creatinine (Cr), blood urea nitrogen (BUN), fasting blood sugar, HbA1C, complete blood count (CBC), hemoglobin, lipid profile, phosphate level, saliva cortisol, and urine melatonin before and after taken longan syrup.
