Plain English Summary
Background and study aims
Sasang constitutional medicine (SCM) is a unique traditional Korean therapeutic alternative form of medicine. SCM classified individuals into 4 types: Taeyang, Soyang. Taeeum, and Soeum. Clinical diagnosis and treatment are done according to the constitution. Taeeum type is considered as a constitution that is easily affected by metabolic syndrome including obesity.
Taeeumjowui-tang is the herbal medicine widely used for taeeum type people. Recent studies have been continued to investigate its effects on obesity, lipid metabolism, metabolic syndrome, and hepatotoxicity.
The aim of this study is to estimate the effect and safety of Taeeumjowui-tang on overweight and obesity with metabolic syndrome risk factors in Taeeum-in constitution diagnosed by SCAT(Sasang Constitutional Analysis Tool) after 12-week oral administration.
Who can participate?
Overweight and obese Taeeum-in (Taeeum type people) with metabolic syndrome risk factors.
What does the study involve?
This is a one-group, pretest-posttest design trial. All participants will be receiving 5g Taeeumjowui-tang, administered 3 times daily, 2 packs at a time.
What are the possible benefits and risks of participating?
Participants will have the chance to be diagnosed by SCAT (Sasang constitutional Analysis Tool) and classified into four constitutions. Potential benefits include improvements in BMI and metabolic syndrome risk factors. Potential side effects include insomnia, excessive sweating, tachycardia, frequent urination, general weakness, mental excitement, anorexia, stomach discomfort, nausea, vomiting, diarrhea, and dysuria.
Where is the study run from?
Cheonan Oriental Hospital and Dunsan Oriental Hospital.
When is the study starting and how long is it expected to run for?
The trial is expected to start on 01/02/2019, and end on 31/05/2020
Who is funding the study?
This work was supported by the National Research Foundation of Korea(NRF) grant funded by the Korea government(MSIT) (Grant Mo.: 2015M3A9B6028311).

The main contact is Dr. Teak-Won Ahn, firstname.lastname@example.org.
The effect of Taeeumjowui-tang on overweight or obesity with metabolic syndrome risk factors in Taeeum-in constitution diagnosed by SCAT (Sasang constitutional Analysis Tool): a non-randomised trial
Recent studies have been continued to investigate the effects of Taeeumjowui-tang on obesity, lipid metabolism, metabolic syndrome, and hepatotoxicity. In Sasang constitutional medicine (SCM), Taeeumjowui-tang is the herbal medicine best suited to taeeum type people. The objective of this study is to investigate whether Taeeumjowui-tang could influence obesity and metabolic syndrome risk factors.

1. Generic drug name : Taeeumjowui-tang
2. The dosage given, the method and frequency of administration : total 30 grams daily, orally administered. (3 times daily, 2 packs at a time. One pack contains 5 grams of Taeeumjowui-tang.)
3. The total duration of treatment : 12 weeks
4. Follow-up: the subjects will have 5 visits: visit 1 screening, visit 2 enrollment, and 3 other visits 4, 8, 12 weeks after visit 2, respectively. (±5 days of error range). On every visit, anthropometric and vital sign data will be collected, and clinical laboratory test will be carried on. Calculation of Body Mass Index (BMI) will also be done on every visit. Any drug combinations and adverse events will be checked on visit 3~5. Clinical drug compliance will be checked on visit 3~5, and on visit 5, the total compliance will be assessed.
Primary outcome measure
Body Mass Index (BMI) will be measured at baseline (visit 2) and 12 weeks later (visit 5)
Secondary outcome measures
1. Improvement in the number of metabolic syndrome risk factors according to the metabolic syndrome criteria (NCEP-ATPIII, 2006 Defining Abdominal Obesity in the Korean Population, Korean Society for the Study of Obesity). Metabolic syndrome is diagnosed when three or more of the following criteria are met.
1.1. Waist circumberence: men ≥ 90 cm, women ≥ 85 cm.
1.2. High fasting glucose: ≥ 100 mg/dL
1.3. Hypertriglyceridemia: ≥ 150 mg/dL
1.4. Low HDL-chol. : men <40 mg/dL , women <50 mg/dL
1.5. High blood pressure: ≥ 130/85 mmHg
2. Dyslipidemia will be determined using changes in triglyceride, total cholesterol, HDL-cholesterol and LDL-cholesterol at baseline, 4 weeks, 8 weeks, and 12 weeks.
3. Changes in blood pressure will be determined by measuring blood pressure (SBP, DBP) at baseline, 4 weeks, 8 weeks, and 12 weeks.
4. Blood sugar will be measured using:
4.1. Changes in FBS (IFG), insulin NS free fatty acid at baseline, 4 weeks, 8 weeks, and 12 weeks.
4.2. Changes in HbA1c at baseline, 8 weeks, and 12 weeks.
5. Obesity factors will be measured using:
5.1. Changes in BMI at baseline, 4 weeks, and 8 weeks.
5.2. Changes in waist circumference at baseline, 4 weeks, 8 weeks, and 12 weeks.
6. Collecting oriental medical information:
6.1. Facial color measurement, voice measurement, body measurement, and questionnaire at visit 5.
6.2. 3D facial measurement at visit 1 and 5.
6.3. Tongue diagnosis, body temperature (Digital Infrared Thermal Imaging) measurement at visit 2 and 5.
7. The changes in glucose metabolism and metabolic syndrome risk factors will be measured using the oral glucose tolerance test (OGTT) on 30 subjects whose fasting blood glucose level is 110 mg/dl or more, and who are not taking diabetes medication.
