The native plant causes serious liver injury in grazing animals, and but tribulus extracts have not been linked convincingly to instances of clinically apparent liver injury when given in typical doses in humans.</p></div><div id="Tribulus.Background"><h3>Background</h3><p>Tribulus is prepared from the leaves and roots of the low-growing shrub and common weed <i>Tribulus terrestris</i> that is found in dry habitats in many parts of the world, including Asia, Africa, Australia and North and South America. Extracts of the shrub have been used in traditional medicine as an aphrodisiac, general tonic and mood stimulant for centuries. A major use of tribulus has been for sexual dysfunction such as erectile dysfunction in men and hypoactive sexual syndromes in women, but also for menopausal symptoms, premenstrual syndrome and infertility. Recently tribulus has been used commonly for increasing athletic performance. Tribulus is also purported to be beneficial for several other medical conditions, including urinary tract infections, kidney stones, hypertension, angina pectoris, hypercholesterolemia, gastrointestinal disorders, diarrhea and even liver disease. Studies in animal models suggested that tribulus increases testosterone levels in males and estrogen levels in females, but these hormonal effects have not been reproduced consistently in humans. Furthermore, in controlled trials, improvements in sexual function were no greater with <i>Tribulus terrestris</i> extracts than with placebo. The active ingredients in extracts of tribulus are believed to be saponins such as dioscine, diosgenin and protodioscin which are steroidal molecules and thought to increase levels of sex hormones. Tribulus is available in tablets and capsules of 250 and 500 mg, and the usual daily dose is 250 to 750 mg daily. <i>Tribulus terrestris</i> is also included in many multi-ingredient dietary supplements used for sexual dysfunction and body building. Tribulus is reported to be well tolerated but may be associated with mild gastrointestinal discomfort, nausea or dyspepsia. The plant, also known as puncture vine because of the sharp spines on its fruit, has been linked to outbreaks of liver injury in grazing animals known as geeldikkop or hepatogenous photosensitivity. The toxic component of the plant is believed to be the steroidal sapogenins which form crystals in bile ducts and renal tubules in sheep that feed upon its leaves.</p></div><div id="Tribulus.Hepatotoxicity"><h3>Hepatotoxicity</h3><p><i>Tribulus terrestris</i> has been not been reported to cause serum enzyme elevations in persons taking the herbal extract, but prospective studies with regular monitoring of liver tests have not been done. Isolated case reports of renal injury with serum aminotransferase elevations have been published but may have represented instances of ischemic or anabolic steroid induced liver and kidney injury rather than direct hepatotoxicity of the extract. Interestingly, the <i>Tribulus terrestris</i> plant is known to be toxic to grazing animals and can cause distinctive liver injury known as “geeldikkop” or hepatogenous photosensitivity. Histology of the liver from sheep dying after feeding upon the leaves of <i>Tribulus terrestris</i> demonstrates crystals in bile ducts and renal tubules.

Severe Jaundice and Renal Dysfunction in a Patient Taking Tribulus.(<a class="bk_pop" href="#Tribulus.REF.1">1</a>)</h3><p>A 30 year old man developed weakness, nausea and poor appetite a few months after starting <i>Tribulus terrestris</i> extract tablets (once daily) as a part of his body building program. He began to feel poorly and over the next 6 weeks lost 50 pounds in weight, eventually developing pruritus and jaundice and seeking medical attention. He had no history of liver disease and drank alcohol only occasionally. His only other medications were naproxen for headaches and protein shakes for nutrition. Laboratory tests showed a total bilirubin of 36 mg/dL (direct 18.7 mg/dL), <a class="def" href="/books/n/livertox/glossary/def-item/glossary.alanine-aminotransferase-alt-/">ALT</a> 90 U/L, <a class="def" href="/books/n/livertox/glossary/def-item/glossary.aspartate-aminotransferase-ast-/">AST</a> 49 U/L and alkaline phosphatase 219 U/L. Tests for hepatitis A, B and C and HIV infection were negative as was the ANA. Abdominal ultrasound showed a homogenous but enlarged liver but no evidence of biliary obstruction. A liver biopsy showed severe cholestasis, no inflammation and no bile duct injury or fibrosis. Tribulus was stopped and he was treated with ursodiol. He was discharged but then readmitted 2 weeks later with persistent jaundice (bilirubin 39 mg/dL) and an increase in serum creatinine from 1.1 to 3.1 mg/dL. One month after the second admission he was seen as an outpatient and both liver and kidney tests had improved.</p><div id="Tribulus.Key_Points"><h4>Key Points</h4><div id="Tribulus.Tc"

The clinical history, laboratory tests and course are typical of anabolic steroid jaundice, which usually presents with severe pruritus and jaundice in an otherwise healthy young male body builder who may or may not admit to use of anabolic steroids. The pattern of liver enzymes is usually a mild-to-moderate increase in serum aminotransferase levels and normal or only minimal increase in alkaline phosphatase despite the marked increase in serum bilirubin. Liver biopsy shows severe canalicular cholestasis with minimal cell injury or inflammation (bland cholestasis) and no fibrosis. Patients with serum bilirubin levels above 30 mg/dL can develop bilirubin nephropathy with bilirubin stained casts. The liver and renal injury can be severe, but are self-limiting and eventually resolve without evidence of chronic injury to either the liver or kidneys. Because anabolic steroids are illegal drugs, patients may refuse to admit that they were being used.</p></div></div></div><div id="Tribulus.PRODUCT_INFORMATION"><h2 id="_Tribulus_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
