Which Fruits Have More Papain?

Dec 13, 2010 | By Owen Pearson

Papain is a proteolytic enzyme that helps keep proteins in certain foods from solidifying. Although the healing powers of papain are relatively new to the United States, this enzyme has a long history of use in other countries. Filipino healers believed that this enzyme could prevent hemorrhoids, according to Michael Castleman, author of "The New Healing Herbs." Javanese physicians recommended it as a remedy for arthritis. Caribbean natives believed that papain could speed labor.

Papaya

Papain is found only in the papaya, a fruit native to the Caribbean, Mexico, the island of Java and the Philippines. It is found in the latex, or milky fluid, between the skin and flesh of this fruit. The papaya is a tropical fruit roughly the size of a large potato, and has a yellow-green skin and juicy orange pulp.

Uses

Papain may help ease digestive distress by aiding in the breakdown of proteins in foods. This may ease the symptoms of ulcers and heartburn. It may also reduce the pain of peptic ulcers caused by frequent use of aspirin and anti-inflammatory drugs, Some natural food enthusiasts also use papain in papayas to tenderize meat, according to Phyllis Balch, author of "Prescription for Nutritional Healing."

Dangers

Avoid using papain if you are pregnant -- this enzyme may induce labor and increase your risk of miscarriage, according to Castleman. It may also cause an allergic reaction that worsens the symptoms of asthma. In rare cases, papain may cause gastritis, or inflammation of your stomach lining. Consult your doctor before using any herbal remedies, especially if you are using other medicines.
