Anacyclus pyrethrum (Akarkara) is an aphrodisiac herb in Ayurveda that is said to enhance male vitality and virility in addition to being a brain tonic. Evidence is preliminary, but it seems to be a pro-fertility agent and testosterone boosting herb with some neuroprotective effects.

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 (similar to Spilanthes Acmella and Maca), 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).

Dosage information

Studies in rats use a range of 50-150 mg/kg bodyweight Anacyclus pyrethrum roots (DC) daily, with all tested extracts (ethanolic, petroleum ether, water) appearing to be effective. This results in an estimated human dosage range of:

  • 550-1,600 mg daily for a 150 lb person
  • 700-2,200 mg daily for a 200 lb person
  • 900-2,700 mg daily for a 250 lb person

These are just estimates as to the effective range of the root extract in humans, since there is currently no human evidence to base recommendations on.
