Pellitory has been used in medicine since ancient times and originates in Algeria , although it is now grown in the Himalayas (cultivated) and various other parts of the world. It can be used as a herb in stews and so on as it has a peppery taste, perhaps because of the piperine–like substance in it. It is a member of the Asteraceae/Compositae or daisy family so is a relative of marigolds, chamomile, which it resembles closely and a whole host of other flowering plants.

Culpeper writing later in the 17th century agrees in the main: -

He also says that it resembles yarrow.
It has also been used as an insecticide and a tonic for the nervous system. In India it is used for malaria and cholera and is given as a tonic to aid digestion. It is applied externally as a poultice or compress for a headache, and also is a traditional aphrodisiac. Some herbalists recommend it for diabetes and for erectile dysfunctions combined with other herbs such as puncture vine.

It has been used as a gargle with cold water and honey to relieve sore throats and relieves the dryness of the mouth and promotes the flow of saliva if chewed. A tincture made from the plant has been used for toothache, either rubbed on the gums or put into a decaying tooth with a cotton wool swab.
The root has been applied as a counter-irritant to joints and limbs afflicted by rheumatism and arthritis and it seems to affect the nerve endings as it causes redness and a tingling sensation. It was once believed that if you chewed the root regularly over a period of several months it would help sufferers of rheumatic and neuralgic pains in the head and face.
The main active ingredient in the volatile oil from pellitory seems to be pyrethrine or pellitorin an alkaloid, along with lignans such as sesamine (also found in sesame seeds), inulin (a starchy substance), and tannins. Lignans such as those found in flax seeds have anti-inflammatory properties.
Research is still being carried out on pellitory so we will have to wait and see what health benefits scientists say this plant has. Probably many of the old uses of the herb will prove to have scientific backing.
