Peppermint oil mainly has the effect of soothing the liver and bile, anti-inflammatory and pain relief, and is often used clinically to treat cholecystitis and gallbladder stone effects. Of course for different symptoms of cholecystitis, need to be treated differently, peppermint oil does not necessarily work for all patients with symptoms of gallbladder. Generally speaking, if the gallbladder infection is in a severe attack, it must be treated in a regular hospital, even including surgery, and peppermint oil may not work. For general symptomatic cholecystitis such as gastrointestinal discomfort, indigestion normal, often with epigastric fullness and discomfort, peppermint oil may have a role to play. Of course peppermint oil treatment should be treated with evidence and should not be treated the same.
