Report on the risk of using Tribulus terrestris in food supplements
Tribulus terrestris L. is a plant from the Zygophyllaceae family whose use in food supplements is authorised in various countries of the European Union. In its natural form, it contains various active substances, the most notable of which are steroidal saponins, b-carboline alkaloids, flavonoids and lignanamides. Tribulus terrestris' toxicity to animals has been widely documented throughout its history as a medicinal plant and it has been reported to have negative neuronal, muscular, hepatic and renal effects. Some countries consider using parts of the Tribulus terrestris plant to produce food supplements to be unsafe, so they do not allow such supplements to be sold. This is reported through the European Rapid Alert System for Food and Feed (RASFF). The Scientific Committee has conducted a risk assessment with the aim of determining whether consuming fruit, plant shoots and extracts from Tribulus terrestris in food supplements is safe, concluding that there is insufficient toxicological data to assess how safe using parts from the Tribulus terrestris plant in food supplements is. In any case, the maximum daily quantity of Tribulus terrestris in food supplements should not exceed the dose used for pharmacological purposes. The part of the plant used, whether it was extracted or prepared in some other way, as well as its saponin content, should all be made clear on the supplement itself. ; ES; en; pfefsa@msssi.es
