Unlike other members of the MYRTACEAE family, eucalyptus or cloves , guava is not very aromatic.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

This small tree, PSIDIUM GUAJAVA, of 3 to 10 m, with very hard wood, is native to tropical America .<\/p>\n\n\n\n

It was introduced very early by Spanish navigators in the Philippines or Portuguese in India; it is now pantropical.<\/p>\n\n\n\n

Its robustness and its ease of dissemination (by birds) make it consider as a plant plague in many islands of the Pacific where it smothers native vegetation on inaccessible mountain slopes.
In tropical America, it is a plant that invades abandoned agricultural land (felled) before being itself covered by higher vegetation which limits its development.<\/p>\n\n\n\n

Birds, wasps, monkeys or humans seek its fruit: the guava.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It is a small round or ovoid fruit 4 to 10 cm in diameter that turns green to yellow when ripe; it contains a sweet pulp of pink to red color, including many hard seeds, yellow or brown, kidney-shaped from 2 to 5 mm.<\/p>\n\n\n\n

CHEMICAL COMPOSITION AND PROPERTIES<\/h2>\n\n\n\n

All parts of the tree are rich in TANNINS, especially the bark (10%) but also the leaves, roots and epicarp of the fruit.<\/p>\n\n\n\n

The average composition of the guava endocarp without seeds reveals 10 to 15% of sugars and a lot of VITAMIN C (25 to 500 mg per 100g depending on the fruit, their maturity and the variety), it is on average 2 to 5 times more than orange juice.<\/p>\n\n\n\n

Guava pulp contains also VITAMIN A, iron, calcium and phosphorus.<\/p>\n\n\n\n

GUAVA SEEDS<\/h2>\n\n\n\n

They are a by-product of guava juice.
The small seeds are lightly roasted to lower humidity, increase oil content percentage and decrease anti-nutritional compounds.<\/p>\n\n\n\n

Average composition (dry weight basis) :
Proteins : 7%
Lipids : 19%
Glucids : 23%
Crude fibers : 43%
Water : 4%
Mineral ash : few %<\/p>\n\n\n\n

An EDIBLE OIL can be chemically extracted from the roasted seeds, average composition :<\/p>\n\n\n\n

Saturated fat : 14%.<\/p>\n\n\n\n

Unsaturated fat : 86%, with a very high percentage of linoleic acid (omega 6) , with cosmetic properties.<\/p>\n\n\n\n

USES<\/h2>\n\n\n\n

Fresh guava is a good source of VITAMIN C.<\/p>\n\n\n\n

The fruit is digestible when peeled and does not have the acidic character of citrus fruits but it does not keep very well.<\/p>\n\n\n\n

Concentrated and dehydrated guava juice is a source of vitamin C which was used during the 2nd world war to improve the rations of the American soldiers.<\/p>\n\n\n\n

It is now found pasteurized in many countries; guava pulp without seeds is used to make excellent jams or jellies.<\/p>\n\n\n\n

In traditional and herbal medicine, leaves, bark, young twigs or green fruits are used to obtain an ASTRINGENT decoction:<\/p>\n\n\n\n

Example: 10 to 20 leaves in 1\/2 to 1 liter of water, boil and reduce by half by boiling.<\/p>\n\n\n\n

It is useful in case of:<\/p>\n\n\n\n

DIARRHEA (one cup twice a day).<\/p>\n\n\n\n

ANGINA, tonsillitis (gargling).<\/p>\n\n\n\n

PRURITUS.<\/p>\n\n\n\n

INFECTED OR OOZING DERMATOSIS (including erysipela) in bath or application.<\/p>\n\n\n\n

LEUCORRHEA, postpartum delivery (vaginal injection or bath).<\/p>\n\n\n\n


GUAVA SEED OIL<\/h2>\n\n\n\n

Cosmetic uses : skin protection.<\/p>\n\n\n\n

Culinary uses : better if mixed with another oil with a much lower content in linoleic acid like canola oil, palm oil .<\/p>\n\n\n\n

GUAVA CULTIVATION<\/h2>\n\n\n\n

The guava tree is a plant from the tropical-equatorial region but there are varieties that adapt to the warm regions of temperate countries, for example: Florida, California, southern Spain, Greece.<\/p>\n\n\n\n

In colder regions, the guava tree must be protected during the winter and is then generally planted in pots.<\/p>\n\n\n\n

Propagation can be done by seeds, by root shoots, by cuttings.
You can graft the guava tree to keep an interesting variety, on another guava tree or on a neighboring species more resistant to diseases such as coronilla (Psidium friedrichsthalianum).
In hot regions the guava tree can become invasive.<\/p>\n\n\n\n

ABSTRACT<\/h2>\n\n\n\n

GUAVA VITAMIN C and tannins<\/p>\n\n\n\n

Guava tree is very common in tropico equatorial regions, its fruit, guava, is eaten locally or exported in the form of juice or jam, it contains a lot of vitamin C.
The leaves, the bark contain tannins which are used (in decoction) to treat all the disorders which require an astringent, for example: infection or inflammation of the mouth, skin or genital infections or diarrhea.<\/p>\n\n\n\n
