Overview Information

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

Bael is used for constipation, diarrhea, diabetes, and other conditions, but there is no good scientific evidence to support these uses.

How does it work?

Bael contains chemicals called tannins, flavonoids, and coumarins. These chemicals help to reduce swelling (inflammation). This might help treat asthma, diarrhea, and other conditions. Also, some of these chemicals help to reduce blood sugar.


Uses & Effectiveness?

Insufficient Evidence for

  • Asthma. Research shows that taking a product that contains bael fruit and boswellia gum helps people with asthma to breathe better. It's unclear if the effects are due to bael, to boswellia, or to the combination.
  • Illness from a Shigella bacteria infection (shigellosis). Early research shows 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.
  • Depression.
  • Diabetes.
  • Diarrhea.
  • Memory.
  • Snakebite, when applied to the skin.
  • Stomach ache.
  • Other conditions.
More evidence is needed to rate the effectiveness of bael for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: There isn't enough reliable information to know if bael is safe to use as medicine. Large amounts may cause stomach upset and constipation.

When applied to the skin: There isn't enough reliable information to know if bael is safe or what the side effects might be.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if bael is safe to use when 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.
