Tara is a small thorny tree from the dry Andes. Its botanical name is Caesalpinia spinosa. People use the pods and the seeds.
The seeds give tara gum, a thickener used in many foods. The pods are very rich in tannins, which taste dry and bitter. In Peru and Bolivia, pod washes and gargles were common home remedies.
One form has caused real harm. Tara flour, made from ground seeds, was linked to hundreds of liver injuries in the United States in 2022. Do not eat it.
Here is the short verdict. Human studies of tara as a remedy are very thin. Long traditional use is not proof that it works, and not proof that it is safe.
Most of what is claimed for tara comes from lab work, not from people. The pods hold tannins, which bind tightly to proteins. That binding is why a pod rinse feels dry and tight in the mouth.
In test tubes, tara tannins slow the growth of some bacteria and fungi. They also mop up free radicals in lab tests. Whether any of that helps a real sore throat is not known.
Tara gum works in a simpler way. It is a soluble fibre that soaks up water and forms a gel. Food makers use it for that reason.
The cause of the liver injuries from tara flour has not been pinned down. Researchers have looked at an unusual amino acid found in the seed. That work is not finished.
Tara reaches most people as tara gum. Labels list it as tara gum or E417. You will find it in ice cream, sauces, dairy desserts and gluten free baking.
Tannin powder and liquid extract are the industrial forms. They are used for tanning leather and for dyes. A few supplement sellers also offer pod extract in capsules.
Dried pods are the traditional form. In the Andes they were boiled into a dark rinse or gargle. Loose pods are still sold in Peruvian markets.
Tara flour is the form to avoid. It is sold in some places as a protein-rich food ingredient. United States regulators have ruled that it is not safe for food.
Tara has been used in the Andes since before the Spanish arrived. Peru is still the main grower. Pods were valued for tanning, ink and dye as much as for remedies.
Healers boiled the pods into a dark rinse. It was gargled for sore throats and swollen tonsils. The same liquid was used to wash cuts, and as a hair rinse for lice.
Some households drank weak pod tea for loose bowels. These uses passed down by word of mouth. They were never tested the way a medicine is tested.
Stop using any tara product and get medical help the same day if you notice signs of liver trouble. These include yellow skin or eyes (jaundice), dark urine, pale stools, pain under the right ribs, or deep tiredness with nausea.
Call emergency services for swelling of the lips, face or throat, or for trouble breathing. That can mean a severe allergic reaction.
See a doctor if a sore throat lasts more than a week, comes with a high fever, or makes swallowing hard.
Tara gum is an approved food additive in the European Union, listed as E417, and is permitted in the United States. Tara flour is different: United States regulators ruled in 2023 that it is not safe for food use. Pod extracts sold as supplements are not approved to treat any illness.
