Pimienta gorda is the dried unripe berry of Pimenta dioica, the tree we call allspice. It is a kitchen spice first and a folk remedy second. The name comes from its smell, which mixes clove, cinnamon and nutmeg.
In Mexico, Guatemala, Jamaica and across the Caribbean it flavours moles, adobos, stews and jerk rubs. Home tradition also used warm teas of the crushed berry for upset stomach, gas and cramps. Crushed berries and the oil were rubbed on sore joints and aching teeth.
Here is the honest evidence verdict. There are almost no human trials of allspice for any health use. Most of what is known comes from test tubes and animals, which cannot tell you what happens in a person.
Traditional use is not proof that something works, and it is not proof that something is safe. That applies to every claim on this page. As food, the spice has a long record of ordinary safe use.
The concentrated essential oil is a different product from the spice. It is far stronger, and it is the form that carries real risk.
No mechanism for allspice has been confirmed in people. What follows is lab and animal work only.
The berry is rich in eugenol, the same compound that gives clove its smell. In test tubes, eugenol numbs nerve endings on contact. Dentists have long used eugenol pastes for this local numbing effect.
In laboratory tests, allspice extracts slow the growth of several bacteria and fungi. Whether that happens inside the gut after you eat the spice is not established.
In cell and animal studies, extracts appear to lower markers of swelling and to mop up free radicals. These are early findings. They have not been shown to ease pain or disease in humans.
Some animal work suggests the spice relaxes gut muscle and may ease cramping. That fits the traditional stomach tea, but it does not confirm it.
Eugenol has also shown blood-thinning activity in lab studies. That matters for drug safety even though the human effect is unclear.
Common forms you will meet:
- Whole dried berries, the usual kitchen form. They keep their oil longest. - Ground powder, sold in supermarkets worldwide.
- Home tea made from crushed berries steeped in hot water. - Essential oil (pimento oil), sold for scent and for dental or topical use. This is highly concentrated.
- Pimento leaf oil, a related product distilled from the leaves. - Capsules of ground spice or extract, sold as supplements. These are not standardised.
- Allspice-scented liniments and rubs.
Food use and essential oil use are not the same thing. Treat the oil as a strong product, not a stronger spice.
Allspice was used by Maya and other peoples of Mesoamerica long before European contact. Records describe it in food, in drink and in embalming.
Spanish sailors met it in the Caribbean and named it pimienta, mistaking it for pepper. Jamaica became the main grower, which gave the Spanish name pimienta de Jamaica.
In Latin American and Caribbean home medicine, warm berry teas were given for indigestion, gas, colic and menstrual cramps. Crushed berries were used in poultices for bruises and joint pain.
In rural dentistry, the oil was dabbed on an aching tooth, much as clove oil was. Folk texts also listed it as a warming tonic after chills.
These are historical records of what people did. They are not recommendations for you to do the same.
Get emergency care if someone has swallowed allspice essential oil, especially a child. Warning signs include vomiting, drowsiness, confusion, seizures or yellow skin and eyes.
Stop use and call your doctor if you notice:
- Easy bruising, nosebleeds or bleeding gums - Dark urine, pale stools or yellowing of the skin or eyes - A spreading rash, swelling of the lips or face, or trouble breathing - Stomach pain that is severe, or that lasts more than a few days
A toothache, blood in your stool or vomit, or unexplained weight loss needs a doctor or dentist, not a home remedy.
In the United States, allspice is an ordinary food spice and is listed by the FDA as generally recognised as safe for that use. In the UK, EU, Mexico and most of Latin America it is sold freely as a food.
Supplement capsules are sold as food supplements and are not tested or approved as medicines. Pure essential oil is sold as a scent or flavouring, not as something to swallow.
