Track Alligator pepper (grains of paradise) with reminders and record whether it helped, in the app.
Alligator pepper is the seed of Aframomum melegueta, a plant in the ginger family. It is also sold as grains of paradise. In West Africa it is both a kitchen spice and a ritual item.
The seeds are hot and sharp, with a hint of citrus. Yoruba speakers call them atare. Cooks use them whole, crushed or ground into pepper blends.
Here is the honest verdict on the evidence. Human research is very thin, and a few tiny trials looked only at how fast the body burns energy. Long use in tradition is not proof that it works, and not proof that it is safe.
Almost all of what is known comes from the lab, not from people.
The seeds hold pungent compounds much like those in ginger. In test tubes these slow the growth of some bacteria. They also lower markers of swelling in cell and animal work.
Whether any of that happens in your body is not known. Nobody has shown that the spice treats an infection or a swollen joint in people.
A few small studies in healthy adults used a seed extract. The rate at which the body burned energy went up for a short time. Researchers think the extract may switch on brown fat, a tissue that makes heat.
That idea is still early. The same studies did not show clear weight loss. Treat it as a lead, not a finding you can rely on.
Whole dried seeds are the common form. Ground seed is sold as a spice, often mixed with other peppers.
You may also find capsules of a dried extract. Some people chew the raw seeds. Others steep them in hot water as a tea.
In folk practice the seeds were soaked in gin or palm wine. Extracts are far stronger than kitchen use. Label strength is often unclear, so two products may differ a lot.
Alligator pepper has been used in West Africa for many centuries. Traders in medieval Europe knew it as grains of paradise.
Yoruba hosts offered atare with kola nut to welcome guests. Elders used the seeds in naming rites and in prayers for a newborn. Healers gave them for stomach upset, chills and poor appetite.
In Europe the seeds flavoured beer, wine and spirits. Britain restricted their use in beer in the 1800s. The spice later came back as a flavouring for gin and craft beer.
Stop and get urgent care if you get a swollen face, lips or tongue, a spreading rash, or trouble breathing. These can be signs of a serious allergic reaction.
See a doctor soon if you have bleeding that will not stop, black or tarry stools, or blood when you are sick.
Book a normal appointment if stomach pain, heartburn or loose stools last more than a few days. Also see a doctor if belly pain, weight loss or low sex drive goes on without a clear cause. Those need a diagnosis, not a spice.
In the United States, grains of paradise is listed by the FDA as a spice and flavouring that is generally recognised as safe. In the UK and the EU it is sold as an ordinary food spice, and extracts are sold as food supplements rather than medicines.

The published evidence for Alligator pepper (grains of paradise) is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
