Aguacate, also called palta, is the fruit of the tree Persea americana. It is a green fruit with creamy flesh and one large seed. In Latin America it is both a daily food and a home remedy.
The pulp is eaten raw, mashed or blended. Folk use goes further than the fruit. The leaves are brewed as a tea, and the oil, pulp and seed are put on skin and hair.
Here is the short verdict. The fruit is well studied as a food, and eating it in place of other fats can lower LDL (the "bad" cholesterol) a little. The leaf and seed remedies have barely been tested in people.
Long use in a tradition is not proof that a remedy works, and it is not proof that it is safe. That applies to the leaf tea and seed powders here. The fruit itself is simply food for most people.
The clearest effect comes from what the fruit is made of, not from any special action. Most of its fat is oleic acid, a monounsaturated fat. Human trials show that swapping saturated fat for this kind of fat lowers LDL cholesterol.
Avocado also brings fibre and plant sterols. Both are known in people to cut how much cholesterol the gut takes up.
Fat helps your body absorb some vitamins. In small human trials, adding avocado to a salad raised the uptake of carotenoids, the colour pigments in carrots and tomatoes. This is a real, measured effect.
Avocado soybean unsaponifiables (ASU) are a processed extract of avocado and soybean oil. In cell and animal studies, ASU appears to slow the breakdown of cartilage. Whether that is what happens in a human joint is not settled.
The leaves contain persin and other plant compounds. In animal studies, leaf extracts have acted as a mild water pill (diuretic) and have lowered blood sugar. These findings have not been confirmed in people.
Fresh fruit is the main form, and the best studied one.
Other forms you may meet:
Avocado oil, sold for cooking and for skin and hair. Avocado soybean unsaponifiables (ASU) capsules, sold for joint pain.
Dried avocado leaves, sold loose for tea. Ground seed powder and seed capsules. Creams, masks and hair oils in cosmetics.
In Latin American markets you may also see the leaf sold fresh, often beside other kitchen herbs.
The forms differ a lot in how well they are tested. Fruit and oil are ordinary food.
ASU has been studied in human joint trials. Leaf tea and seed powder have very little human data behind them.
Avocado has been grown in Mexico and Central America for thousands of years. Seeds have been found at sites dating back many centuries BCE.
Healers in the region used far more than the pulp. Leaf tea was taken for stomach upset, coughs, period pain and to pass more urine. The seed was ground and used for diarrhoea and for parasites.
The oil and pulp were rubbed on dry skin, burns, scalp and hair. Spanish records from the colonial era noted these uses.
The fruit later spread worldwide as a crop. The food use travelled; the leaf and seed medicine mostly stayed home.
Call emergency services at once if you get swelling of the lips, tongue or throat, trouble breathing, or widespread hives after eating avocado. This can be a severe allergic reaction.
See your doctor soon if you get an itchy mouth or throat each time you eat it. That pattern needs allergy testing.
Stop avocado leaf tea and speak to your doctor if you feel dizzy, shaky or unwell, or if your blood sugar readings drop.
Tell the clinic that checks your warfarin if you start eating avocado every day.
Avocado is an ordinary food and is sold freely worldwide. Avocado oil is sold as food and as a cosmetic. ASU extract is sold as a supplement in the United States and the United Kingdom, and is a prescription medicine in France.
