In the charcoal meal test fifteen (15) Sprague Dawley rats were randomized to a control group (normal saline 5 ml/kg orally, n¼5), a positive control group (atropine sulfate 0.1 mg/kg i.p., n¼5) and a test group (400 mg/kg B. biternata extract, n¼5). Charcoal meal was then administered via oral gavage to each rat thirty (30) minutes after the administration of the various treatments. The distance covered by the charcoal meal from the pylorus was then determined after sacrifice of the animals thirty minutes after the meal.
