Tribulus terrestris, commonly known as Puncturevine, is a creeping annual plant native to the Asian region. Although it is considered a weed in many respects, its effects are invaluable. It is a natural stimulant of testosterone levels, not only in men but also in women, which can be beneficial, for example, when trying to conceive. In men, it helps improve spermatogenesis, potency, and also increases their libido. In medicine, it is also used in the treatment of heart disease and high blood pressure.
