广藿香的水提物、去油水提物和挥发油均可抑制离体兔肠的自发收缩和乙酰胆碱、氯化钡引起的痉挛性收缩，对乙酰胆碱和氯化钡引起的收缩作用强度顺序是：挥发油＞去油水提物＞水提物。在整体实验中，广藿香水提物和去油水提物均能抑制正常小鼠胃肠推进运动和新斯的明引起的小鼠胃肠推进运动亢进，对抗番泻叶引起的小鼠腹泻。而广藿香挥发油反促进腹泻。结果提示广藿香改善肠道功能和抗腹泻的有效成分可能为水溶性成分。
Patchouli water extract, oil-water extract and volatile oil can inhibit spontaneous contraction of isolated rabbit intestine and acetylcholine, barium chloride induced spastic contraction of acetylcholine and barium chloride contraction caused by the intensity of the order: Volatile Oil> De-Oil Water Extract> Water Extract. In the whole experiment, patchouli water extract and de-oiling water extract can inhibit gastrointestinal propulsion in normal mice and neostigmine-induced gastrointestinal motility in mice and antagonize the diarrhea in mice induced by senna. Patchouli Volatile Oil promotes diarrhea. The results suggest that patchouli may improve intestinal function and anti-diarrhea effective ingredients may be water-soluble ingredients.
