Alder Buckthorn Bark

Frangula is a shrub that grows in wet conditions in many countries. It has greenish flowers and dark red berries. Bark is used from the larger branches of the shrub, and is collected in the spring.

Frangula is a remedy for constipation, similar to senna and rhubarb, but milder. The hydroxyanthracene glycosides and bitter principles that it contains give it a stimulating laxative action that is effective but relatively gentle. They also contribute a general toning action to the digestive tract. Resolving constipation frequently has a beneficial effect on the whole digestive system, and may remove or reduce many diverse symptoms, including the symptoms of IBS.

Avoid excessive doses. Start with the minimum dose and increase slowly if it is not effective.
