Overview Information

Bael is a plant. The unripe fruit, root, leaf, and branch are used to make medicine.

People use bael for constipation and diarrhea.

How does it work?

Bael contains chemicals called tannins, which help treat diarrhea by reducing swelling (inflammation).


Uses & Effectiveness?

Insufficient Evidence for

  • Diarrhea. Early research suggests that taking dried bael fruit powder for 3 days does not reduce the number of stools in people with diarrhea caused by an infection called shigellosis.
  • Constipation.
  • Other conditions.
More evidence is needed to rate the effectiveness of bael for these uses.

Side Effects

Side Effects & Safety

There isn't enough information to know if bael is safe. Large amounts may cause stomach upset and constipation.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking bael if you are pregnant or breast-feeding. Stay on the safe side and avoid use.

Diabetes: Bael might lower blood sugar levels. If you have diabetes and take medications to lower your blood sugar, adding bael might make your blood sugar drop too low. Monitor your blood sugar carefully.

Surgery: There is a concern that bael might interfere with blood sugar control during and after surgery. Stop using bael at least 2 weeks before a scheduled surgery.



We currently have no information for BAEL Interactions.



The appropriate dose of bael depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for bael. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
