Pellitory of Spain is the dried root of Anacyclus pyrethrum, a low daisy-like plant from North Africa and the Mediterranean. Old English herbals call it Bertram. In South Asian shops the same root is sold as akarkara.
Its signature is physical. Chew a sliver and the mouth burns, tingles and floods with saliva. That is why it was used for ages in mouth remedies, tooth powders and gargles.
Do not confuse it with pellitory of the wall, which is Parietaria and a different plant entirely.
Human evidence for Pellitory of Spain is very thin. Most claims rest on tradition and on lab or animal work. Long use in a tradition is not proof that something works, and it is not proof that something is safe.
The tingling and the rush of saliva are real and easy to observe. They come from oily compounds called alkylamides, chiefly pellitorine. These act on nerve endings in the mouth lining.
That local effect is the only part that is clearly established in people. Whether it helps a tooth, a throat or anything else has not been shown in good trials.
In male rats, root extracts raised testosterone and mating behaviour. In cell and animal tests, extracts appear to damp down inflammation and to stir the immune system.
None of those findings have been confirmed in people. Treat them as leads, not as results you can count on.
You will meet it in a small number of forms.
- Dried root pieces, sold whole or cut, for chewing - Root powder, loose or in capsules, often labelled akarkara - Tinctures (alcohol extracts), used in drops or in gargles - Tooth powders and mouth rinses - Occasional mixed formulas sold for male sexual health
The essential oil exists but is rare and harsh. It is not for swallowing. Most consumer products are the plain powdered root.
European healers knew the root mainly as a chewing remedy. Greek and Roman writers described a pyrethron root that burned the mouth, and medieval herbals carried the idea forward.
By the 1600s English writers such as Culpeper listed it for toothache, for a dull or heavy head, and for a tongue that would not move after a stroke. Chewing it to draw saliva and phlegm was the common method.
It also travelled east. Unani and Ayurvedic practice adopted it as akarkara, where it was given for male sexual complaints, weak nerves and aching joints.
These are historical uses, recorded here as history. They are not reasons to treat yourself with the root today.
Call emergency services at once if your lips, tongue or throat swell, if your breathing gets tight, or if you come out in widespread hives. That is an allergic reaction.
Stop using it and see a doctor or dentist if you get mouth ulcers that do not heal within a few days, if you have ongoing stomach pain or vomiting, or if you develop a rash.
See a dentist urgently for a toothache with facial swelling, fever or a bad taste from the gum. That suggests an abscess, which needs treatment.
In the UK, the EU and the US it is sold as a food or dietary supplement, not as a licensed medicine. No regulator has approved it to treat or prevent any condition.
