Custard apple seeds contain potent bioactive compounds, specifically annonaceous acetogenins, which are potent toxins with insecticidal properties. This is the primary reason why custard apple seed powder is used as a natural biopesticide and an anti-lice agent, but these same compounds also pose significant health risks to humans.

Over 99% of people who accidentally swallow a single, whole custard apple seed experience no ill effects. While the seed's kernel is toxic if crushed and ingested, its hard shell typically prevents the release of harmful compounds, allowing it to pass harmlessly through the digestive system.
