Tribulus is an antidepressant, aphrodisiac, fertility enhancer and bodybuilding
tonic. It is used in the treatment of eczema, heart disease and Parkinson's disease and
has had one of the longest documented 'clinical trials' in history.
MAOIs(mono-amine-oxidase-inhibitor) act in the brain by stopping the breakdown
of certain chemicals, one of which is dopamine. This is a chemical that is low in people
suffering Parkinson's disease and explains why the ancients used Tribulus for tremors.
The Ayurvedics added Tribulus to another herb to treat for Parkinsonian tremors called
Mucuna. This contains L-dopa, the direct precursor of dopamine in the brain. Tribulus
basically helps you absorb the L-dopa and stops its breakdown. This is exactly the same
as the modern treatment for Parkinson's-a combination of L-dopa and a MOAI. There is
nothing new under the sun!
Because the harmine(main active ingredient in Tribulus)contained in Tribulus acts
as a MOAI, this leads to higher levels of dopamine in the brain. Dopamine though, is not
just involved in movement. It is one of the brains happy chemicals-the higher the
dopamine levels, the stronger, better and happier you feel.
High dopamine levels in men also stimulate the pituitary gland to release
leutenizing hormones which in turn leads to an increase in testosterone levels. This
enhances libido, increases strength and lean muscle tissue and makes you feel great.
In both men and women, high dopamine levels lead to increased growth hormone
production. This is the major body repair hormone and is currently being used in anti-
There is also a chemical in Tribulus called a furoctanol biglycoside which enhances sperm production and motility, therefore increasing male fertility. Another chemical,
terrestrioside-F, enhances the libido in both men and women.
Another interesting modern finding is that Tribulus seems to dilate the coronary
arteries around the heart and therefore benefits heart disease sufferers. This circulatory
effect is also useful for those with high blood pressure and hardening of the arteries.
