"Pear" here means the avocado, Persea americana. In Trinidad and Tobago it is often called pear or avocado pear. In Haiti it is zaboka, and in Cuba it is aguacate.
It is a green, buttery fruit with one large seed. Across the Caribbean it is eaten daily as food. The leaves and the seed are also brewed or grated for home remedies.
The short evidence verdict: eating the fruit has real but modest effects on blood fats. The leaf and seed remedies rest on tradition, not on good human trials. Long traditional use is not proof that something works, and it is not proof that it is safe.
Most of what the fruit measurably does comes from its fat and fibre, not from a drug-like compound.
The flesh is rich in monounsaturated fat, the kind found in olive oil. In human trials, swapping other fats for this one lowers LDL ("bad") cholesterol a little. The change is small, not dramatic.
Fat and fibre together slow how fast a meal leaves the stomach. In small human studies, people said they felt fuller after a meal with avocado added.
The leaf and seed claims sit on much weaker ground. In animal and test-tube work, avocado leaf extracts lowered blood pressure and blood sugar. Whether that happens in people who drink the tea is not established.
The leaves, skin and seed also hold persin, a natural plant compound. It is known to poison birds and some farm animals. Its effect in humans has barely been studied.
Most people meet avocado as food: the ripe flesh, eaten plain or mashed.
Fresh fruit. This is the form with the best human evidence behind it.
Avocado oil. Pressed from the flesh, used for cooking and in skin and hair products.
Leaf tea. Fresh or dried leaves steeped in hot water, a common home drink in Haiti and Cuba.
Ground seed. The pit is dried, grated and stirred into water or other drinks in some households.
Capsules and extracts of leaf or seed. Sold online as supplements. Strength and purity are not well controlled.
Skin and hair masks. Mashed flesh or oil, left on and rinsed off.
Avocado soybean unsaponifiables (ASU). This is a processed extract sold for joint pain, and it is not the same thing as eating the fruit.
Avocado reached the Caribbean from Central America long before Europeans arrived, and spread further during the plantation era. Many households kept a tree in the yard, for food first and medicine second.
Caribbean folk practice used leaf tea for colds, fever, gas and high blood pressure. In Haiti, zaboka leaf tea was a common drink for an upset stomach.
Ground seed was used for diarrhoea and for aching joints. In some places it was also taken to bring on a late period. That use is why leaf and seed preparations were treated as unsafe in pregnancy.
The oil and the mashed flesh were rubbed into dry hair, cracked skin and burns.
Call emergency services if your lips, tongue or throat swell, or if you struggle to breathe after eating avocado. That is a severe allergic reaction.
See a doctor soon if you get hives, repeated vomiting, or belly pain after leaf tea or ground seed. Stop the preparation first.
Contact your doctor if you take warfarin (a blood thinner) and notice new bruising or bleeding.
Get checked if you have kidney disease and feel weak, tired or notice an irregular heartbeat. These can be signs of high potassium.
Avocado is an ordinary food and is sold freely in the United States, the United Kingdom, the European Union and across the Caribbean. Leaf and seed capsules are sold as food supplements, not as approved medicines, so no health claim on the label has been checked by a regulator.
