Where is Tribulus
herb found?
Tribulus terrestris herb grows naturally in many parts of
the world including the Americas, Australia, Europe, the Middle East, and
Africa. Tribulus is considered a noxious weed found abundantly on roadsides and vacant
lots whose seeds are sharp and painful to step on. The foliage of tribulus is toxic to livestock, especially sheep, when consumed
daily in large
quantities. The fruits / berries of tribulus are the parts most often used in traditional medicine. The
composition of different substances within tribulus is likely to vary depending
where in
the world it grows.

Lack of adequate human
research
Tribulus
terrestris herb has not been studied by Western scientists to any great extent
and there's a lot we don't know about the benefits and side effects of this
interesting plant. Although tribulus terrestris herb has been used in folk
medicine for many conditions, modern science has not yet adequately
evaluated this herb in terms of its clinical use, so we don't know what medical
conditions this herb
could benefit. However, there is
good confidence that tribulus terrestris is useful as a sexual enhancement herb.
Tribulus terrestris has been promoted and marketed for athletic
performance, muscle mass enhancement, and as a testosterone booster.
Does it work for this purpose? See below for research on
this topic.
Tribulus
Terrestris Benefit as sexual enhancer
One rodent study found tribulus to be helpful as a sex booster. Sexual behavior and
intracavernous pressure (ICP) were studied in both normal and castrated rats to further
understand the role of tribulus as an aphrodisiac. ICP refers to blood flow into the corpus
cavernosa of the penis. Adult rats were divided into groups of 8 each that included
distilled water treated (normal and castrated), testosterone treated (normal and
castrated, 10 mg/kg body weight) and tribulus treated (castrated, 5 mg/kg body weight).
Decreases in body weight, prostate weight and ICP were observed among the castrated groups
of rats compared to the intact group. Compared to the castrated control, treatment of
castrated rats (with either testosterone or tribulus extract) showed increase in prostate weight
and ICP. There was also a mild to moderate improvement in sexual behavior as evidenced by
an increase in mounting frequency.
Our experience and feedback from users of tribulus supplement are
consistent. Tribulus terrestris supplement does enhance sexuality in the
majority of those who take it. The sexual enhancement is noticed within a few
days. Passion Rx is more effective is it has a number of herbs that provide a
more comprehensive approach to sexual improvement.
Additional Tribulus
Terrestris Benefit - Much more research is needed to confirm these early
findings
Tribulus has been studied in China and early reports indicate it reduces the frequency of angina pectoris. Laboratory studies have found tribulus
to have anti-microbial and anti-tumor potential. Tribulus may also lower blood levels of cholesterol, and, in addition, tribulus
has antioxidant properties.
Additional benefits of tribulus terrestris extract
include hepatic protection from certain toxins and blood sugar control.
These early reports have to be confirmed by larger trials before we can be
certain that this herb is useful for these purposes.
Tribulus
Terrestris and athletic performance
Tribulus terrestris, by itself, does not
appear to improve athletic performance, not does tribulus seem to influence
testosterone levels in humans to any great extent.
The effect of five weeks of Tribulus
terrestris supplementation on muscle strength and body composition during
preseason training in elite rugby league players.
J Strength Cond Res. 2007 May;21(2):348-53. Rogerson S, Riches CJ, Jennings
C, Weatherby RP, Meir RA, Marshall-Gradisnik SM. School of Exercise Science and
Sport Management, Southern Cross University Lismore, New South Wales, Australia.
Although some manufacturers claim tribulus terrestris will not lead to a
positive drug test, others have suggested that tribulus terrestris may increase
the urinary testosterone / epitestosterone ratio, which may place athletes at
risk of a positive drug test. The purpose of the study was to determine the
effect of tribulus terrestris on strength, fat free mass, and the urinary
testosterone / epitestosterone ratio during 5 weeks of preseason training in
elite rugby league players. Twenty-two Australian elite male rugby league
players were match-paired and randomly assigned in a double-blind manner to
either a tribulus terrestris or placebo group. All subjects performed structured
heavy resistance training as part of the club's preseason preparations. A
tribulus terrestris extract (450 mg each day)) or placebo capsule was consumed
once daily for 5 weeks. Muscular strength, body composition, and the urinary
testosterone / epitestosterone ratio were monitored prior to and after
supplementation. After 5 weeks of training, strength and fat free mass increased
significantly without any between-group differences. No between-group
differences were noted in the urinary testosterone / epitestosterone ratio. It
was concluded that tribulus terrestris did not produce the large gains in
strength or lean muscle mass that many manufacturers claim can be experienced
within 5 to 28 days. Furthermore, tribulus terrestris did not alter the urinary
testosterone / epitestosterone ratio and would not place an athlete at risk of
testing positive based on the World Anti-Doping Agency's urinary testosterone /
epitestosterone ratio limit of 4:1.
Tribulus
Terrestris
Mechanism of Action
Tribulus may work by relaxing smooth muscles and increasing blood flow into the corpus
cavernosa. The relaxant effect observed is probably due to the increase in the release of
nitric oxide from the endothelium and nerve endings. Since tribulus relaxes smooth muscles, this
may account for its benefits in abdominal colic. Tribulus extract also
influences testosterone levels but long term human studies are not available to
determine what influence tribulus supplements would have on testosterone and
free testosterone levels in the blood when taken for several weeks or months..
What's in Tribulus Terrestris?
The fruits of tribulus contain a number of different
substances including saponins, glycosides, flavonoids, alkaloids, resins, tannins, sugars,
sterols, and essential oil.
Recently, two new saponins have been isolated from tribulus
terrestris: Terrestrinins A and B, .
A frequently mentioned substance in tribulus
terrestris is
protodioscin, which some claim is one of the active substances within this plant. When
different samples of tribulus were analyzed, significant differences in the composition
of saponins
were observed depending on the origin and plant part used. One analysis of products showed
considerable variations of 0.17 to 6.5 % in protodioscin content.
Availability of
Tribulus Terrestris supplement
Tribulus terrestris supplement is most often found in combination with other sex-enhancing herbs.
Tribulus terrestris
is also sold by itself often in a dosage ranging from 250 to 750 mg. Tribulus
supplement is
found in a variety of extract potencies.
Tribulus Terrestris side effects
No tribulus terrestris side effects have yet been reported in the medical
literature. However, little is
known about the long-term use of tribulus supplement consumption in humans. As with most
herbs, it is best to take breaks from use. According to Dr. Ray Sahelian, M.D.,
an expert in sexual herbs, and the author of Natural Sex Boosters, he mentions
in the book high doses of tribulus terrestris supplement can lead to a
feeling of restlessness, insomnia, and rapid heart beat. Another tribulus side
effect he mentions in increased body temperature.

Tribulus Terrestris Research Studies
Tribulus terrestris and cancer
It appears from lab studies that tribulus terrestris may cause death to cancer
cells. The clinical significance of this finding is not clear at this time.
Saponins from Tribulus terrestris L are less toxic for
normal human fibroblasts than for many cancer lines: influence on apoptosis and
proliferation.
Exp Biol Med (Maywood). 2007 Jan;232(1):126-33. Medical University, Sofia
1431, Bulgaria
The objective of the study was to explore the influence of saponins derived from
Tribulus terrestris on normal human skin fibroblasts and to compare it with
their anticancer properties... According to our results, Tribulus terrestris is
less toxic for normal human skin fibroblasts in comparison to many cancer lines
investigated in previous studies. The molecular mechanism of this cytotoxicity
involves up- and downregulation of polyamines' homeostasis, suppression of
proliferation, and induction of apoptosis. Further research in this field using
animal models would help to explore and interpret the potential properties of
Tribulus terrestris as an anticancer supplement.

Inhibitory effects of saponins from Tribulus
terrestris on alpha-glucosidase in small intestines of rats]
Zhongguo Zhong Yao Za Zhi. 2006 Jun;31(11):910-3. School of Life Science,
East China Normal University, Shanghai 200062, China.
To determine the effects of saponins from Tribulus terrestris on small
intestinal a-glucosidase and postprandial blood glucose levels in rats. METHOD:
The inhibitory effects of saponins from Tribulus terrestris on a-glucosidase
extracted from small intestines in rats were carried out in vitro. The blood
glucose levels were measured after 60 min when sucrose (2 g x kg(-1)) or glucose
(2 g x kg(-1)) was administered orally with saponins from Tribulus terrestris
(100 mg x kg(-1)). After treated with saponins from Tribulus terrestris (100 mg
x kg(-1)) for 14 d, the activities of a-glucosidase were determined daily, as
well as the postprandial blood glucose levels after oraly administered sucrose
(2 g x kg(-1)). It was through inhibiting the activity of a-glucosidase
in small intestines that saponins from Tribulus terrestris significantly
retarded the increase in postprandial blood glucose levels in rats.
Tribulus
terrestris liver
protection
Recovery of phosphatase and transaminase activity of mercury
intoxicated Mus musculus (Linn.) liver tissue by Tribulus terrestris (Linn.) (Zygophyllaceae)
extract. Trop Biomed. 2006 Jun;23(1):45-51. Department of Zoology, Faculty
of Science, Annamalai University, Annamalainagar - 608 002.
The efficacy of the methanolic fraction (MF) of Tribulus terrestris fruit
extract on mercury intoxicated mice, Mus musculus has been studied. At a
median-lethal dose of mercuric chloride administration an enhanced level of
glutamate oxaloacete transaminase (GOT), glutamate pyruvate transminase (GPT)
and simultaneously decreased level of acid phosphatase (ACP) and alkaline
phosphatase (ALT) activities were noticed in the liver. Due to the mercury
toxicity the liver cells are damaged to cause the alterations in their enzymes.
During the recovery period, all the enzymological parameters are restored to
reach near normal level. The result suggested that the oral administration of MF
of Tribulus terrestris fruit extract has provided protection against the
mercuric chloride induced hepatic damage in the mice, M. musculus.
Tribulus terrestirs and sexual health
Sexual behavior and intracavernous pressure (ICP) were studied in both normal and
castrated rats to further understand the role of tribulus containing protodioscin (PTN) as
an aphrodisiac. Adult Sprague-Dawley rats were divided into five groups of 8 each that
included distilled water treated (normal and castrated), testosterone treated (normal and
castrated, 10 mg/kg body weight, subcutaneously, bi-weekly) and
tribulus treated (castrated, 5
mg/kg body weight, orally once daily). Decreases in body weight, prostate weight and ICP
were observed among the castrated groups of rats compared to the intact group. There was
an overall reduction in the sexual behaviour parameters in the castrated groups of rats as
reflected by decrease in mount and intromission frequencies (MF and IF) and increase in
mount, intromission, ejaculation latencies (ML, IL, EL) as well as post-ejaculatory
interval (PEI). Compared to the castrated control, treatment of castrated rats (with
either testosterone or tribulus extract) showed increase in prostate weight and ICP that were
statistically significant. There was also a mild to moderate improvement of the sexual
behaviour parameters as evidenced by increase in MF and IF; decrease in ML, IL and PEI.
These results were statistically significant. It is concluded that tribulus extract appears to possess aphrodisiac activity.

The purpose of this study was to determine the effects of the herbal preparation
Tribulus terrestris (tribulus) on body composition and exercise performance in
resistance-trained males. Fifteen subjects were randomly assigned to a placebo
or tribulus (3.21 mg per kg body weight daily) group. Body weight, body
composition, maximal strength, dietary intake, and mood states were determined
before and after an 8-week exercise (periodized resistance training) and
supplementation period. There were no changes in body weight, percentage fat,
total body water, dietary intake, or mood states in either group. Muscle
endurance (determined by the maximal number of repetitions at 100-200% of body
weight) increased for the bench and leg press exercises in the placebo group (p
<.05; bench press +/-28.4%, leg press +/-28.6%), while the tribulus
terrestris group
experienced an increase in leg press strength only (bench press +/-3.1%, not
significant; leg press +/-28.6%, p <.05). Supplementation with tribulus does not
enhance body composition or exercise performance in resistance-trained males.

Tribulus terrestris and
androgen
- testosterone effect
The aphrodisiac herb Tribulus terrestris does not influence the androgen
production in young men.
J Ethnopharmacol. 2005 Oct 3;101(1-3):319-23. Department of Chemistry and
Biochemistry, Medical University, 2 Zdrave str., Sofia-1431, Bulgaria.
The aim of the current study is to investigate the influence of Tribulus
terrestris extract on androgen metabolism in young males. Twenty-one healthy
young 20-36 years old men with body weight ranging from 60 to 125 kg were
randomly separated into three groups-two experimental (each n=7) and a control
(placebo) one (n=7). The experimental groups were named TT1 and TT2 and the
subjects were assigned to consume 20 and 10 mg/kg body weight per day of
Tribulus terrestris extract, respectively, separated into three daily intakes
for 4 weeks. Testosterone, androstenedione and luteinizing hormone levels in the
serum were measured 24 h before supplementation (clear probe), and at 24, 72,
240, 408 and 576 h from the beginning of the supplementation. There was no
significant difference between Tribulus terrestris supplemented groups and
controls in the serum testosterone, androstenedione; controls or luteinizing
hormone. All results were within the normal range. The findings in the current
study anticipate that Tribulus terrestris steroid saponins possess neither
direct nor indirect androgen -increasing properties.
Saponins in tribulus
terrestris
A novel furostanol saponin from Tribulus terrestris of
Bulgarian origin.
Conrad J, Dinchev D.
Department of Chemistry, University of Hohenheim, 70593 Stuttgart, Germany..
Fitoterapia. 2004 Mar;75(2):117-22.
The phytochemical investigation of the aerial parts of Tribulus terrestris of
Bulgarian origin has resulted in the isolation of the novel furostanol saponin
1, named tribol, together with the known spirostanol saponins 2 and 3 and
sitosterol glucoside.
Tribulus terrestris
saponin composition from different tribulus plant species
Distribution of steroidal saponins in Tribulus terrestris from different
geographical regions.
Phytochemistry. 2007 Aug 22; Dinchev D, Janda B, Evstatieva L, Oleszek W,
Aslani MR, Kostova I. Institute of Organic Chemistry with Centre of
Phytochemistry, Bulgarian Academy of Sciences, Sofia 1113, Bulgaria.
The steroidal saponins of Tribulus terrestris L. (Zygophyllaceae) are considered
to be the factor responsible for biological activity of products derived from
this plant. The activity depends on the concentration and the composition of
active saponins, which in turn is influenced by the geographical origin of plant
material. Samples of Tribulus. terrestris collected in Bulgaria, Greece, Serbia,
Macedonia, Turkey, Georgia, Iran, Vietnam and India were analyzed for the
presence and the concentration of protodioscin (1), prototribestin (2),
pseudoprotodioscin (3), dioscin (4), tribestin (5) and tribulosin (6). The
flavonoid rutin (7) was also included in the comparison. The results revealed
distinct differences in the content of these compounds depending on region of
sample collection, plant part studied and stage of plant development. The
samples from Bulgaria, Turkey, Greece, Serbia, Macedonia, Georgia and Iran
exhibited similar chemical profile and only some quantitative difference in the
content of 1-7 with protodioscin and prototribestin as main components. The
Vietnamese and Indian samples exhibit totally different chemical profile. They
lack 2 and 5, while tribulosin is present in high amounts. Most probably, the
Vietnamese and Indian samples belong to other chemotypes which are still to be
studied and characterized.
Comments: There may be differences in composition between certain
regions, but the clinical significance of these differences in terms of sexual
enhancement or erectile function has yet to be determined.
Tribulus Terrestris questions
Q. If tribulus terrestris is stopped
after using for one month, is there any type of side effect?
A. We are not aware of any side effects or problems if tribulus
terrestris supplement is stopped after
one month of use.
Q. Is Bulgarian tribulus superior to tribulus from
other countries?
A. There is no human research comparison studies to indicate
whether Bulgarian tribulus terrestris is any
better in terms of sexual enhancement than tribulus terrestris that grows in other countries.
We have not seen research comparing Bulgarian tribulus versus German
tribulus, or American tribulus, etc..
Q. Does tribulus increase testosterone levels?
A. We have come across many
websites that report tribulus increases testosterone levels but we have not come
any long term human research that has looked into testosterone levels over
several weeks or months of tribulus supplement use. Perhaps tribulus does raise levels of
testosterone but at this point we are not sure. And even if it does, we don't know
whether it would do so consistently if tribulus is taken for prolonged periods.
Q. What is Tribulus Fuel? Do you have such a Fuel
Tribulus review?
A. Tribulus Fuel is the product name of a tribulus formulation. We
don't have a review of Tribulus Fuel.
Q. Can tribulus be combined with other herbs such as yohimbe,
maca, or hormy goat
weed?
A. We can only speak from our personal and professional experience. Thus far
we
have combined tribulus with several herbs and have not found any
significant side effects when used in low dosages.
Q. Does tribulus give more energy?
A. Tribulus has some energy boosting abilities, as do ginseng, cordyceps,
maca, and tongkat ali.
Q. Is tribulus appropriate for a woman?
A. Tribulus can be used by a woman or man.
Q. Can tribulus be taken regularly for many months?
A. As with most herbs, we recommend taking breaks from use. In the case of tribulus you could take it for 1 or 2 weeks on, 1 or 2 weeks off.
Q. Is it possible that chronic use, increasing over
time due to tolerance, of OTC herbals such as tribulus terrestris can lead
to secondary hypogonadism due, such as the HTPA axis being so imbalanced
that it cannot easily be restarted?
A. The hormonal influence of tongkat ali, tribulus terrestris, and
many other herbs, when used on a chronic basis, is not fully known since
human studies are few, but this, and other scenarios, are theoretically
possible. We always recommend people take breaks from the use of herbs
such as tribulus terrestris. In most people,
Q. How long after I start taking tribulus
terrestris should I expect results?
A. Everyone is different, but on average most people would notice the
benefits from tribulus on the third or fourth day of use. It also depends on
dosage. If your tribulus dosage is low, it may take a couple of days or more.
Q. How many different types of tribulus extracts are available?
A. There are many extract potencies of tribulus terrestris, the
most common being tribulus terrestris powder,
tribulus 20% extract, and tribulus 40% extract. There are other tribulus
extracts but they are not as common.
Q. Do you have a review of Twinlab Tribulus
supplement? I just want to know the best tribulus product.
A. We don't have a review of Twinlab Tribulus. We have no reason to
believe it would not be a good product. There are many companies that make
tribulus, and since the raw material is not very expensive, we suspect the
vast majority of the tribulus supplements on the market to be of good
quality. Therefore, we can't say what the best tribulus supplement is on
the market today.
Q. Is the right spelling tribulus terestris? I have
seen terestris used with one r.
A. The correct spelling is terrestris.
Q. Does tribulus extract really work as a sexual enhancing herb?
A. Yes, tribulus terrestris extract does help with healthy erectile function,
but it takes several days for the full benefits.

Q. Is Bulgarian tribulus extract a more effective aphrodisiac herb than
tribulus herb grown in other countries?
A. Tribulus terrestris is a plant that grows on several continents.
Since human research is lacking regarding comparisons of tribulus
terrestris herb from different countries, one cannot say that Bulgarian
tribulus is better than tribulus herb grown in the United States. Much of
the chemical composition of this herb depends on how the tribulus plant is
grown, the soil conditions, temperature, the harvesting, processing,
storing, etc.

Q. I have recently been taking tribulus terrestris pills and noticed quite
an effect as it relates to sexual performance. Mainly harder erections and
much greater stamina. I am not a drug user or even a fan of alcohol, but I
must say a pill like this is very addicting. My question is, does taking
tribulus terrestris extract or even Passion Rx for extended periods of
time (4 weeks, or longer) have any long term effects? I have noticed when
taking a week break that I begin to have a hard time keeping an erection,
and it never truly reaches the potential as with the tribulus pills, and
when it does become hard, endurance is out of the question, as I am
finished within seconds. My concern is that I may be lowering my natural
testosterone levels and could be affecting my sexual performance for the
future. Its difficult when your significant other becomes used to one way,
and without the pills you cannot perform. Is there a psychological issue
perhaps?
A. It is a good idea to take more frequent breaks from the use of
tribulus terrestris supplements or other sexual herbs. One option is to
experiment with different herbs so that your break from tribulus pills is
longer. Other options include catuaba, muira puama, tongkat ali, avena
sativa, horny goat weed, mucuna pruriens, and the two variations of
Passion Rx.

Tribulus terrestris
questions
Q. In your opinion, which would have the
superior effect on boosting testosterone levels in a deficient DHEA /
testosterone male. Bulgarian tribulus 300 mg (50% protodioscin) or DHEA 25 MG. I
understand that tribulus terrestris and DHEA supplements are a favorite among
consumers for boosting testosterone levels.
A. DHEA would increase tesstosterone levels more but there are
serious side effects and dangers with DHEA use. Tribulus terrrestris may not
have a significant effect long term on testosterone, but it is the safer
supplement to use.
Q. I took a tribulus terrestis product one
capsule and did not notice much. The next day I took four capsules and had side
effects of rapid heart beat and higher body temperature, I felt hotter than
normal. Does this mean tribulus terrestis is not an effective sexual product for
me?
A. Not necessarily. Herbs take longer to work and it is preferable
to take lower dosages over several days as opposed to a quick effect with
several capsules.
Q. How long does it take to get a
testosterone boost after taking a tribulus terestris supplement? And what dosage
of tribulus terestris is best to get a quick testosterone effect?
A. There's still some research that needs to be done in humans
before we determine in more detail how tribulus extract use influences hormone
levels, and for how long, and whether the effects wear off after long term use.
Tribulus terrestis, sex, tribulus testosterone tribulus.
Q. Tribulus terristris is an ingredient
that I see in a sexual formula that I bought this week. The product also lists
epimedium, maca, and several other herbs. Is tribulus terristris the most potent
of these herbs?
A. Much of the potency of an herb depends on how concentrated the
extract is. All the herbs you mentioned are effective sexual enhancers.
