HEALTH TIP: The soursop fruit, also known as graviola (Portuguese) guanábana (Spanish), or corossol (French) is a large, green fruit with a dull spiked surface, found mainly in tropical regions. It comes from a small evergreen tree with dark green leaves. You can eat it ripe by tearing off the green surface. A ripe soursop fruit can be very soft and easy to tear apart with the fingers. On the inside is a soft creamy pulp embedded with numerous black seeds. The pulp, the seeds, and even the leaves and bark can be of significant health benefits.
