Apple Guava - Psidium guajava

Order:Myrtales  Family:Myrtaceae  Genus:Psidium

dern-day researchers to study guava extracts. Its traditional use for diarrhea, gastroenteritis and other digestive complaints has been validated in numerous clinical studies. A plant drug has even been developed from guava leaves (standardized to its quercetin content) for the treatment of acute diarrhea. Human clinical trials with the drug indicate its effectiveness in treating diarrhea in adults. Guava leaf extracts and fruit juice has also been clinically studied for infantile diarrhea. In a clinical study with 62 infants with infantile rotaviral enteritis, the recovery rate was 3 days (87.1%) in those treated with guava, and diarrhea ceased in a shorter time period than controls. It was concluded in the study that guava has "good curative effect on infantile rotaviral enteritis."

Guava has many different properties that contribute to its antidiarrheal effect: it has been documented with pronounced antibacterial, antiamebic and antispasmodic activity. It has also shown to have a tranquilizing effect on intestinal smooth muscle, inhibit chemical processes found in diarrhea and aid in the re-absorption of water in the intestines. In other research, an alcoholic leaf extract was reported to have a morphine-like effect, by inhibiting the gastrointestinal release of chemicals in acute diarrheal disease. This morphine-like effect was thought to be related to the chemical quercetin. In addition, lectin chemicals in guava were shown to bind to E-coli (a common diarrhea-causing organism), preventing its adhesion to the intestinal wall and thus preventing infection (and resulting diarrhea).

The effective use of guava in diarrhea, dysentery and gastroenteritis can also be related to guava's documented antibacterial properties. Bark and leaf extracts have shown to have in vitro toxic action against numerous bacteria. In several studies guava showed significant antibacterial activity against such common diarrhea-causing bacteria as Staphylococcus, Shigella, Salmonella, Bacillus, E. coli, Clostridium, and Pseudomonas. It has also demonstrated antifungal, anti-yeast (candida), anti-amebic, and antimalarial actions.

In a recent study with guinea pigs (in 2003) Brazilian researchers reported that guava leaf extracts have numerous effects on the cardiovascular system which might be beneficial in treating irregular heat beat (arrhythmia). Previous research indicated guava leaf provided antioxidant effects beneficial to the heart, heart protective properties, and improved myocardial function. In two randomized human studies, the consumption of guava fruit for 12 weeks was shown to reduce blood pressure by an average 8 points, decrease total cholesterol levels by 9%, decrease triglycerides by almost 8%, and increase "good" HDL cholesterol by 8%. The effects were attributed to the high potassium and soluble fiber content of the fruit (however 1-2 pounds of fruit was consumed daily by the study subjects to obtain these results!). In other animal studies guava leaf extracts have evidenced analgesic, sedative, and central nervous system (CNS) depressant activity, as well as a cough suppressant actions. The fruit or fruit juice has been documented to lower blood sugar levels in normal and diabetic animals and humans. Most of these studies confirm the plant's many uses in tropical herbal medicine systems.

CURRENT PRACTICAL USES

Guava, known as the poor man's apple of the tropics, has a long history of traditional use, much of which is being validated by scientific research. It is a wonderful natural remedy for diarrhea - safe enough even for young children. For infants and children under the age of 2, just a cup daily of guava fruit juice is helpful for diarrhea. For older children and adults, a cup once or twice daily of a leaf decoction is the tropical herbal medicine standard. Though not widely available in the U.S. market, tea-cut and powdered leaves can be obtained from larger health food stores or suppliers of bulk botanicals. Newer in the market are guava leaf extracts that are used in various herbal formulas for a myriad of purposes; from herbal antibiotic and diarrhea formulas to bowel health and weight loss formulas. Toxicity studies with rats and mice, as well as controlled human studies show both the leaf and fruit to be safe and without side effects.

Traditional Preparation: The fruit and juice is freely consumed for its great taste, nutritional benefit and nutrient content, as well as an effective children's diarrhea remedy. The leaves are prepared in a standard decoction and dosages are generally 1 cup 1-3 times daily.

Contraindications:

Guava has recently demonstrated cardiac depressant activity and should be used with caution by those on heart medications.

Guava fruit has shown to lower blood sugar levels and it should be avoided by people with hypoglycemia.

Drug Interactions: None reported, however excessive or chronic consumption of guava may potentiate some heart medications.
