Background

American pawpaw (Asimina triloba) is a fruiting tree native to North America. However, plantings of the tree can be found in Asia, Australia, and Europe. Pawpaw extract is made from the twigs of the tree.

In the 1980s and 1990s, researchers at Purdue University isolated compounds from pawpaw bark extracts. Many of these compounds were found to have cytotoxic effects on cancer cell lines. Currently, there is a lack of available scientific evidence supporting the safety or effectiveness of pawpaw for any condition.

Evidence

DISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Cancer treatment: Pawpaw extract may have some anticancer activity, but additional study is needed to make a firm recommendation.
Grade: C

Lice: Pawpaw extract in combination with thymol and tea tree oil in a shampoo formulation may be effective for the eradication of lice. Better-quality study using pawpaw alone is needed before a firm recommendation can be made.
Grade: C

Tradition

WARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Antibacterial, antifungal, anti-inflammatory (for the mouth and throat), antiprotozoal, antiviral, emetic (induced vomiting), fat substitute, fever reducer, food uses, insecticide (nematodes), pesticide, scarlet fever, skin rashes.

Dosing

Adults (18 years and older)

Dosing from scientific studies has not been proven safe or effective. For cancer, 12.5-50 milligrams of extract has been taken by mouth four times a day with food for periods of up to 18 months. For lice, 40 milliliters of Paw Paw Lice Remover Shampoo® (0.5% pawpaw extract, 1% thymol, and 0.5% tea tree oil) applied three times to dry hair, once every 8 days for up to 24 days, has been used.

Children (younger than 18 years)

Dosing from scientific trials has not been proven safe or effective. For lice, 40 milliliters of Paw Paw Lice Remover Shampoo® (0.5% pawpaw extract, 1% thymol, and 0.5% tea tree oil) applied three times to dry hair, once every 8 days for up to 24 days, has been used.
