Medicated leaven, particularly bran-perched or burnt varieties, enhances digestive function. This study found processed leaven improved pepsin action and gastrointestinal functions in mice compared to raw products.

Area of Science:

  • Gastroenterology
  • Biochemistry
  • Food Science

Background:

  • Digestive health is crucial for nutrient absorption and overall well-being.
  • Medicated leaven has been traditionally used to aid digestion.
  • Understanding the biochemical impact of different leaven preparations is essential.

Purpose of the Study:

  • To compare the digestive effects of raw versus processed medicated leaven.
  • To investigate the influence of medicated leaven on gastric acid and pepsin activity.
  • To evaluate the impact on gastrointestinal motility and function in a murine model.

Main Methods:

  • Analysis of free and total acid content in gastric samples.
  • Assessing pepsin activity in the stomachs of hungry mice.

  • Monitoring gastrointestinal functions and intestinal activity in mice.
  • Comparative analysis of raw and processed medicated leaven products.

    • Main Results:

    • Processed medicated leaven demonstrated enhanced pepsin activity.
    • Significant improvements were observed in impelling functions and intestinal activity.
    • Bran-perched or burnt leaven showed superior effects compared to other preparations.

    Conclusions:

    • Bran-perched or burnt medicated leaven is more effective for invigorating spleen function and promoting digestion.
    • Processed leaven offers superior benefits for gastric acid and pepsin activity.
    • These findings support the use of specific medicated leaven preparations for digestive health.
