Can I drink Bael juice?

Bael is highly laxative in nature, to the extent that it can even be violent sometimes.

Ash gourd juice is better. It works more gradually and more gently.

Bael is a little like isabgol - if taken too often, it can hinder our natural cleaning system, because when one stops taking them, constipation occurs. 

Having Bael fruit/juice once a week, in season, is ok. But it should not be consumed every day.
