Abstract

|
|
Objectives : Decoction is a method of extraction by boiling herbal to dissolve the chemicals of the material. The decocting method is a pharmacological extraction method in Korea. When decocting herbal medicines, the volume of water is an important factor. The aim of this research was to determine the proper amount of water when decocting herbal medicines.
Methods : When water boiled without herbal medicines, the amount of water evaporation was measured. The total volume of water is determined by the amount of herbal water absorption, extraction and the water evaporation.
Results : When the total amount of water was below 200ml, the water evaporation was 40%. Therefore the water evaporation was measured by this formula [(extraction + water evaporation) × 0.4]
Conclusion : When the amount of herbal medicines increased, the volume of water should be increased also.
