Pedalium murex

Last Updated: September 28, 2022

Pedalium Murex is a herb traditionally used alongside Tribulus Terrestris for male enhancement and urinary/genital health. It has minimal evidence, but appears to have similar bioactivities as Tribulus (although one study suggests Pedalium increases testosterone).


Pedalium murex is most often used for


Pedalium Murex is a fruit-bearing herb that has its history intertwined with Tribulus Terrestris due to the visual similarities of the two fruits and their traditional interchanging in Goshukra formulas. Pedalium fruits are much less studied than Tribulus fruits currently.

Preliminary evidence suggests that Pedalium could increase testosterone and act as an aphrodisiac, although there are no human studies currently. The exact bioactives in Pedalium are equally unknown, and all that can be said is that many of the bioactivities of Pedalium are somewhat similar to Tribulus.

There is currently insufficient toxicity information on Pedalium Murex, although three rat studies suggest that there is not a low LD50 to be concerned with (in regards to overt toxicity, no in-depth organ histologies or blood panels have yet been conducted).

Dosage information

There is insufficient human evidence to recommend an appropriate dose, but 200mg/kg of the ethanolic fruit extract appears to be effective in rats. This is an estimated human dose of 32mg/kg and thus:

  • 2,200mg for a 150lb person
  • 2,900mg for a 200lb person
  • 3,600mg for a 250lb person

It is not known if these are optimal dosages for humans due to lack of testing.
