Indications of the frangula

Occasional or chronic constipation , hemorrhoids , productive cough .

Heads up! As with almost all laxatives, it is not advised to use it on a long-term basis (the constituents, the anthracene derivatives found in this plant can be irritating to the gastrointestinal system) as there is a risk of loss of electrolytes (minerals, ….). Talk to your doctor or pharmacist for advice on the cause of constipation if it lasts for several weeks. More and more people believe they suffer from constipation when they don’t go to the bathroom once a day, but this can be normal, while some people go to the bathroom once every five days, and that can be considered constipation.

Secundary effects

Loss of electrolytes (minerals like potassium,…), cramps in the gastrointestinal region, intestinal sluggishness,… Please read the medication leaflet.


Acute intestinal inflammations (eg Crohn’s disease), in case of constipation over a long period; pregnancy, breastfeeding,… Please read the package leaflet for the medications.
