Latin name: Anacyclus pyrethrum DC (Asteraceae), A. officinarum Hayne
Sanskrit/Indian name: Akarakarabha, Akarkara
Anacyclus pyrethrum (pellitory, Spanish chamomile, or Mount Atlas daisy) is a perennial herb much like chamomile in habitat and appearance. It is in a different family (Asteraceae) from the plants known as pellitory-of-the-wall (Parietaria officinalis) and spreading pellitory (Parietaria judaica). It is found in North Africa, elsewhere in the Mediterranean region, in the Himalayas, in North India, and in Arabian countries. Medicinally, pellitory root has a pungent efficacy in relieving toothache and promoting a free flow of saliva and making it popular as a food spice. It induces heat, tingling and redness when applied to the skin. Although one might assume from the pyrethrum suffix that this plant may contain pyrethrins, it does not. The second part of the binomial name stems from the Ancient Greek name for the plant, whereas the pyrethrins are named after Pyrethrum, used more recently for several plants of the genus Chrysanthemum some of which do contain pyrethrins.
