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.
Anacyclus pyrethrum is a pro-fertility and virility enhancing herb that is currently in preliminary
testing in rodents. The main bioactives in this plant are the alkylamides, and preliminary
evidence seems to confirm its traditional claims of fertility and libido enhancement as well as its
role as a ‘brain tonic’ (since it appears to have anti-amnesiac and anti-convulsive effects).
Supplementation of Anacyclus pyrethrum ethanolic root extract (50-150mg/kg) over 28 days in
rats noted dose-dependent increases in testosterone and luteinizing hormone to approximately
two-fold of baseline (exact values not given). It is though anacyclyus works via stimulating the
hypothalamus, as the alkylaimde class of molecules have been known to work in this manner.
A water extract of Anacyclus pyrethrum at 50-100mg/kg over 28 days appears to possess libido
enhancing properties due to enhancing the penile erection index (202%), mounting and
intromission frequency (increases of 196-266% and 173-384%, respectively), and latency time
for mounting and intromission (82-90% and 63-76% of baseline, respectively).
