Efficacy and Safety of Longan Syrup in Healthy Volunteers With Insomnia

Study Overview
=================
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Insomnia severity index | Insomnia severity index after taken longan syrup will be less than before taken. The minimum and maximum values are 0 and 28 scores, respectively. Higher scores mean a worse outcome. | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Thai- The Pittsburgh Sleep Quality Index | Thai- The Pittsburgh Sleep Quality Index after taken longan syrup will be less than before taken. The minimum and maximum values are 0 and 21 scores, respectively. Higher scores mean a worse outcome. | 3 months | 
| Snoring, Tiredness, Observed apnea, blood Pressure, Body mass index, Age, Neck circumference and Gender questionaire | Snoring, Tiredness, Observed apnea, blood Pressure, Body mass index, Age, Neck circumference and Gender questionaire (STOP - BANG) after taken longan syrup will not be more than before taken. The minimum and maximum values are 0 and 8 scores, respectively. Higher scores mean a worse outcome. | 3 months | 
| Epworth sleepiness scale | Epworth sleepiness scale after taken longan syrup will be less than before taken. The minimum and maximum values are 0 and 24 scores, respectively. Higher scores mean a worse outcome. | 3 months | 
| Actiwatch value | Actiwatch value after taken longan syrup will be better than before taken. | 3 months | 
| Serum cortisol | Serum cortisol value at 8.00 o'clock (normal value 5-23 mcg/dL) after taken longan syrup will not be less than before taken. | 3 months | 
| Saliva cortisol | Saliva cortisol at 20.00 o'clock (normal value 3.9 +/- 0.2 nmol/L (range 2.2-4.1 nmol/L)) after taken longan syrup will not be more than before taken. | 3 months | 
| Urine Melatonin | Urine Melatonin overnight (in ng/mL) after taken longan syrup will not be less than before taken. | 3 months |
