- Brief Summary
The investigators will conduct a randomized, double-blind, placebo-controlled study to investigate the effects and safety of the combination seed extracts of Cassia obtusifolia Linne and Foeniculum vulgare Mill in patients with chronic constipation for 4 weeks.
- Detailed Description
A previous animal study has indicated that the combined seed extracts of Cassia obtusifolia Linne and Foeniculum vulgare Mill have a laxative effect by recovering stool parameters, colonic morphology, and activation of mAchRs and their downstream signaling pathway in constipation. Furthermore, this study provides that the combined seed extracts of Cassia obtusifolia Linne and Foeniculum vulgare Mill could be considered as a therapeutic drug candidate for the prevention or treatment of constipation. Therefore, the investigators a randomized, double-blind, placebo-controlled study to investigate the effects and safety of the combination seed extracts of Cassia obtusifolia Linne and Foeniculum vulgare Mill in patients with chronic constipation for 4 weeks. The Investigators examine stool transit time, constipation Visual Analogue Scale (VAS), Bristol stool Form scale type 3 and 4 (frequency per week), VAS for Irritable Bowel Syndrome (VAS-IBS) questionnaire, IBS severity scoring system, BS Quality of Life instrument at baseline, as well as after 2 and 4 weeks of intervention. Interferon-1β and tumor necrosis factor-α concentrations were measured at baseline and 4 weeks. One hundred adults were administered either 1,000 mg of the combined seed extracts of Cassia obtusifolia Linne and Foeniculum vulgare Mill or a placebo each day for 4 weeks.

- Primary Outcome Measures
Name Time Method Change in Colonic transit time during 2 weeks At the 2nd weeks after the start of the study The number of retained radiopaque markers on a Day 4 plain abdominal film
Change in Colonic transit time during 4 weeks At the 4th weeks after the start of the study The number of retained radiopaque markers on a Day 4 plain abdominal film
- Secondary Outcome Measures
Name Time Method Change in Interferon-1β during 4 weeks At 4th weeks after the start of the study concentration (U/ml)
Change in Constipation Visual Analogue Scale during 2 weeks At the 2nd weeks after the start of the study The minimum score was 0, the maximum score was 100, and higher scores mean a worse outcome.
Change in Irritable Bowel Syndrome severity scoring system during 2 weeks At the 2nd weeks after the start of the study Among the questions, categorical questions asking about abdominal pain or bloating are excluded from the score calculation, and the remaining 5 questions are rated from 0 to 100 points using the Visual Analogue Scale. The total score is 500 points. Higher scores mean a worse outcome.
Change in Visual Analogue Scale for Irritable Bowel Syndrome during 4 weeks At the 4th weeks after the start of the study All except item 1 are rated from 0 to 100 points using the Visual Analogue Scale. A total of 700 points is obtained. Higher scores mean a better outcome.
Change in Visual Analogue Scale for Irritable Bowel Syndrome during 2 weeks At the 2nd weeks after the start of the study All except item 1 are rated from 0 to 100 points using the Visual Analogue Scale. A total of 700 points is obtained. Higher scores mean a better outcome.
Change in Tumor necrosis factor-α during 4 weeks At 4th weeks after the start of the study concentration (pg/ml)
Change in Constipation Visual Analogue Scale during 4 weeks At the 4th weeks after the start of the study The minimum score was 0, the maximum score was 100, and higher scores
Change in Bristol stool Form scale type 3 and 4 (frequency per week) during 2 weeks At the 2nd weeks after the start of the study Frequency of Bristol stool Form scale types 3 and 4 per week
Change in Irritable Bowel Syndrome Quality of Life instrument during 2 weeks At the 2nd weeks after the start of the study 5 points for 'not at all', 4 points for 'somewhat', 3 points for 'moderate', 2 points for 'very much', and 1 point for 'severe' (i.e., count opposite the number on the questionnaire). Higher scores indicate higher quality of life.
