Aegeline is a chemical found in the bael plant. It is also made in a laboratory.

Despite safety concerns, aegeline has been used for weight loss, athletic performance, and increased energy, but there is no good scientific evidence to support these uses.

Aegeline has been included in dietary supplements marketed for weight loss and muscle building. In 2013, the U.S. Food and Drug Administration (FDA) issued warning letters to the manufacturer of these products stating that aegeline is not recognized as a lawful ingredient for supplements.
When taken by mouth: Aegeline is POSSIBLY UNSAFE. Liver damage has been reported in people taking a product containing aegeline. Symptoms included fatigue, nausea, stomach pain, dark urine, and jaundice. In some cases, liver damage resulted in death.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if aegeline is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.
