Iberogast side effects
Several clinical reports on the iberogast review have been documented, with all the results showing little to no side effect on the use of the herbal drug.
However, a recent study linked the use of iberogast to liver damage.
This is because of greater celandine (Chelidonium majus) in the drug.
In a 2-year study to examine the hepatotoxic potential of greater celandine, 10 cases of acute hepatitis were recorded.
The victims were patients who used the drug to treat gastric and biliary disorders.
However, after the discontinuation of the medication, a rapid recovery was seen in all patients, and their liver enzyme levels returned to normal within 2 to 6 months.
This shows that greater celandine can induce acute (cholestatic) hepatitis.

Warning and storage instructions
Patients with existing liver disease, a pregnant and breastfeeding mother, should not take the drug unless under doctors’ supervision.
