The 'papaya' (from
Carib via
Spanish), is the
fruit of the
tree ''Carica papaya'', in the genus ''
Carica''. It is native to the tropics of the Americas, and was cultivated in
Mexico several centuries before the emergence of the
Mesoamerican classic cultures.
Nowadays, the papaya is also known as 'fruta bomba' (Cuba), 'lechosa' (Venezuela, Puerto Rico, the Philippines and the Dominican Republic), 'mamão', 'papaw' (
Sri Lankan English), 'Papol' 'Guslabu' (Tree melon - in
Sinhalese ), 'pawpaw' or 'tree melon', as well as 'tree melon' (木瓜) in
Chinese and 'đu đủ' in
Vietnamese.
It is a small tree, the single stem growing from 5 to 10 m tall, with spirally arranged
leaves confined to the top of the trunk; the lower trunk is conspicuously scarred where leaves and fruit were borne. The leaves are large, 50-70 cm diameter, deeply palmately lobed with 7 lobes. The tree is usually unbranched if unlopped. The
flowers are similar in shape to the flowers of the ''
Plumeria'' but are much smaller and wax like. They appear on the axils of the leaves, maturing into the large 15-45 cm long, 10-30 cm diameter fruit. The fruit is ripe when it feels soft (like a ripe
avocado or a bit softer) and its skin has attained an amber to orange hue. The fruit's taste is vaguely similar to
pineapple and peach, although much milder without the tartness, creamier, and more fragrant, with a texture of slightly over-ripened
cantaloupe.
Cultivation and uses

Papaya output in 2005
Originally from southern
Mexico,
Central America and northern
South America, the papaya is now cultivated in most countries with a
tropical climate like
Brazil,
India,
South Africa,
Sri Lanka and the
Philippines.
The ripe fruit is usually eaten raw, without the skin or seeds. The unripe green fruit of papaya can be eaten cooked, usually in curries, salads and stews.
Papaya is rich in an enzyme called
papain, a
protease which is useful in
tenderizing meat and other proteins. Its ability to break down tough meat fibers was utilized for thousands of years by indigenous Americans. It is included as a component in powdered meat tenderizers, and is also marketed in tablet form to remedy
digestive problems.
Papain is also popular (in countries where it grows) as a topical application in the treatment of cuts, rashes, stings and burns. Papain ointment is commonly made from fermented papaya flesh, and is applied as a gel-like paste.
Caution should be taken when harvesting, as papaya is known to release a latex fluid when not quite ripe, which can cause irritation and provoke allergic reaction in some people. The papaya fruit and leaves also contains
carpaine, an
anthelmintic alkaloid which could be dangerous in high doses.
Women in India, Pakistan, Sri Lanka, and other parts of the world have long used papaya as a folk remedy for contraception and abortion. Medical research in animals has confirmed the contraceptive and abortifacient capability of papaya, and also found that papaya seeds have contraceptive effects in adult male langur monkeys, possibly in adult male humans as well.
[1] Unripe papaya is especially effective in large amounts or high doses. Papaya is not
teratogenic and will not cause miscarriage in small, ripe amounts.
Phytochemicals in papaya may suppress the effects of
progesterone.

The black seeds are edible and have a sharp, spicy taste. They are sometimes ground up and used as a substitute for
black pepper. In some parts of Asia the young leaves of papaya are steamed and eaten like spinach.
Excessive consumption of papaya, as of carrots, can cause
carotenemia, the yellowing of soles and palms which is otherwise harmless.
The papaya fruit is susceptible to the
Papaya Fruit Fly. This wasp-like fly lays its eggs in young fruit.
