Tribulus Summary:

Trubulus is a small shrub that can be found growing all over the world, including the harsh environments of the desert. Theyhave the ability to adapt quickly and change their growth pattern depending on the climate they are growing in. 

Medicinally, the leaves and aerial parts are used to treat heart conditions, and sexual dysfunctions. The mechanism of action is much the same, improving blood flow via cardiac innervation and by improving microcirculation.

In traditional Chinese medicine, the fruit is reportedly used for chest pain, skin lesions, and swollen or painful eyes [6]. 

In Ayurveda, the fruit has been used to treat urinary tract infections and inflammations, as well as reproductive disorders. [6]. 

In Unani medicine, tribulus has been used as a diuretic, mild laxative, and general tonic [8]. 

Overall, the traditional uses of tribulus involves its use as a tonic, aphrodisiac, palliative, astringent, stomachic, antihypertensive, diuretic, lithotriptic, for chest pains, paifnul swollen eyes, and urinary tract infections [5]. 


    Botanical Description:

    Tribulus is a small hardy herb, found growing in even the most extreme dry climates. The leaves tend to grow outward in a flat patter, but may grow in a more upward pattern if in a shadier location. 

    The seeds have sharp, rigid spines on them [6]. 


    Habitat Ecology, and Distribution:

    Tribulus is considered an invasive weed in many regions of the world. [6]. 


    Harvesting Collection, and Preparation:

    Although the fruit has been used in the past, the leaves are considered superior and are the preferred part used today [6]. 

     


    Constituents:

    Tribulus leaves contain steroidal saponins (mainly furostanol glycosides including protodioscin and prototribestin), as well as small quantities of spirostanol glycosides, phytosterols (beta-sitosterol), harmala alkaloids (tryptophan-derived beta-carbolines)(some debate as to the presence of this however) [1-4, 7]. 


    Pharmacology and Medical Research:

     

    Cartioprotective

    The constituent tribulosin was shown to protect the myocardium against ischemia/reperfusion injury (through protein kinase C epsilon activation) [9]. 

     

    Aphrodisiac

    [10]. 

     

    Toxicity

    The LD50 of tribulus leaf extract was found to be greater than 10g/kg in mice. this indicates very low toxicity. [6]. 

     

    Cautions:

    • Some Tribulus products marketed towards performance enhancement have been found to contain anabolic steroids [6]. be cautious of this and only purchase from reputable companies. 
    • The root and fruit of tribulus have also been sold as supplements, however, there is indication that these are not suitable for equal substitution for the leaf [6]. 

    Traditional Chinese Medicine:

    Still compiling research. 


    Synergy:

    • Tribulus fruit has often been employed with Withania in Ayurvedic formulas. [6]. Synergy may be present between these 2 herbs.
