Graviola (Annona muricata) is a tropical evergreen tree in the Annonaceae family native to the Caribbean, Central America, and northern South America. It bears large glossy leaves, green spiny fruit, and pale flowers, while the leaves and fruit are the parts most often mentioned in traditional household use.

In tropical herbal traditions, graviola has been prepared in teas, fresh fruit preparations, and other local remedies. It is more strongly associated with tropical home use than with classic European herb gardens, and because different parts of the plant vary widely, careful identification and cautious use are important.
