Mull Seetha, commonly called Soursop, is a tropical fruit tree known for its large, green fruits covered with soft spines (mull). The fruit is oval to heart-shaped, with a tender spiny outer skin.

The pulp inside is white, soft, fibrous, and very juicy, with a sweet–sour flavor and pleasant aroma. It is widely used for fresh consumption, juice, smoothies, ice creams, and desserts.

The tree is a small to medium-sized evergreen, well suited for warm tropical climates and well-drained soils. Mull Seetha is also valued in traditional practices for its nutritional and medicinal properties, as the fruit is rich in vitamin C, fiber, and antioxidants.
