Description
Tribulus (Tribulus terrestris)
Tribulus, also known as caltrops, goathead, bindii or puncture vine, has a long history in Chinese, Ayurvedic and Arabic herbal traditions. Its fruit has traditionally featured in preparations associated with urinary wellbeing, reproductive wellbeing and general vitality.
These historical uses reflect traditional herbal practice. They should not be interpreted as established benefits of this product, as human clinical evidence remains limited.
Traditional Uses and Wellbeing
Traditional herbal references describe Tribulus in connection with:
- Urinary wellbeing and fluid balance
- Reproductive wellbeing, libido and sexual vitality
- Wellbeing during menopause
- Cardiovascular wellbeing
- Physical vitality
- Digestive and respiratory wellbeing
These uses provide historical context rather than confirmation of clinical effectiveness. Results may differ between preparations, and traditional use does not establish that a product will deliver a particular health outcome.
Research into Tribulus
Research has explored Tribulus in relation to sexual function, hormone activity, cardiovascular function, urinary processes, metabolic markers and inflammation.
Much of this research involves laboratory or animal studies. These findings do not establish equivalent benefits in humans or demonstrate the effectiveness of this particular product.
Human studies examining muscle strength and sports performance have not established the substantial improvements sometimes associated with Tribulus marketing. Findings also vary between preparations because plant part, geographical origin, composition and standardisation can differ.
Key Constituents
Tribulus contains naturally occurring steroidal saponins, including protodioscin and compounds identified in the supplied monograph such as tribulosin and terrestrinins A and B.
The monograph also describes other constituents, including beta-sitosterol, vitamin C, minerals and alkaloids.
Constituent levels vary according to the plant part, growing region and stage of development. This botanical information does not confirm the composition or concentration of any particular finished product.
Important Information
In traditional herbal descriptions, Tribulus is characterised as neutral and moist.
Tribulus is not recommended during pregnancy or breastfeeding because safety information is insufficient.
