Support your libido with dry extracts from Bulgarian Tribulus, Yohimbe, Ginkgo biloba and Nettle root.*
How and Why It Works?
VemoHerb® Men’s Formula is very suitable for supporting the sexual health of middle-aged men, used in cases of low sexual activity caused by physical overwork and stress.* [1 – 7]
The combination of active ingredients is especially selected, complementing and helping each other synergistically in physiological aspect so that the properties and the application of the supplement is endorsed.
The aphrodisiac effects of the extract from Pausinystalia yohimbe are due to the yohimbine, which promotes the blood flow in the organs in the pelvis, and the sexual desire.* [2, 6, 8] These properties of the yohimbine are strengthened by the ginkgo flavone glycosides in the extract from Ginkgo biloba, the hydroxycoumarins, sterols and zinc in the extract from Urtica dioica, and the furostanol saponin protodioscin in the Bulgarian Tribulus terrestris extract.
The ginkgo flavone glycosides influence positively the male sex hormones and together with the terpenoids, support the blood circulation in the limbs.* They help the activity of the cardio-vascular and nervous systems and have positive influence in cases of physical overwork and stress.* [3, 9]
The hydroxycoumarin derivatives, sterols and zinc support the natural production of testosterone and influence positively the prostate health.* The properties of the Urtica dioica extract to encourage sexual desire are additionally empowered by the yohimbine in the dietary supplement blend.* [2, 3, 6, 8]
Protodioscin in combination with the other furostanol saponins from the Bulgarian Tribulus terrestris extract positively influence the hormonal balance (especially of sex hormones) in both sexes.*[1, 10, 11, 12] In women, they work on the levels of pregnenolone, progesterone, and estrogens and enhance the libido, thus in general supporting the physical and psycho-emotional health.* [13, 14] Together with the yohimbine, these biologically active substances help the natural hormone production, particularly testosterone, enhance sexual desire and show aphrodisiac properties.
VemoHerb Men’s Formula is a very effective way of improving sexual relations, which are an important part of living a normal life.* [2 – 6, 15]

1. Gauthaman, K. and Ganesan, A. – The hormonal effects of Tribulus terrestris and its role in the management of male erectile dysfunction – an evaluation using primates, rabbit and rat. Phytomedicine (2008) 15: 44.
Hormonal effects of Tribulus terrestris (TT) were evaluated in primates, rabbit and rat to identify its usefulness in the management of erectile dysfunction (ED). TT extract was administered intravenously, as a bolus dose of 7.5, 15 and 30 mg/kg, in primates for acute study. Rabbits and normal rats were treated with 2.5, 5 and 10mg/kg of TT extract orally for 8 weeks, for chronic study. In addition, castrated rats were treated either with testosterone cypionate (10mg/kg, subcutaneously; biweekly for 8 weeks) or TT orally (5mg/kg daily for 8 weeks). Blood samples were analyzed for testosterone (T), dihydrotestosterone (DHT) and dehydroepiandrosterone sulphate (DHEAS) levels using radioimmunoassay. In primates, the increases in T (52%), DHT (31%) and DHEAS (29%) at 7.5mg/kg were statistically significant. In rabbits, both T and DHT were increased compared to control, however, only the increases in DHT (by 30% and 32% at 5 and 10mg/kg) were statistically significant. In castrated rats, increases in T levels by 51% and 25% were observed with T and TT extract respectively that were statistically significant. TT increases some of the sex hormones, possibly due to the presence of protodioscin in the extract. TT may be useful in mild to moderate cases of ED.

In this study the effects of yohimbine and sildenafil on cold stress-induced erectile dysfunction in rats were investigated. Yohimbinehydrochloride (0.2 mg/kg, i.p.) and sildenafil citrate (20 mg/kg, i.p) were administered to rats 1h before the stress session daily for 14 consecutive days and their effect was assessed. Results of this section revealed that, immersion of rats in cold water significantly decreased sexual arousal and motivation as indicated by increased latencies and intervals. Furthermore decreased copulatory performance and potency as indicated by decreased ejaculation frequency was observed. Decreased copulatory activity was confirmed by decreased testosterone, luteinizing hormone (LH) and follicle-stimulating-hormone (FSH) levels as well as decreased cholesterol content in rat testes. Treatment with yohimbine or sildenafil significantly increased the sexual arousal and potency and corrected the effects induced by stress on the mating behavior of male rats. On the contrary they did not significantly alter testosterone, FSH and LH levels which is reflected by failure of both drugs to alter cholesterol content in rat testes. Regarding the effect of yohimbine and sildenafil on isolated rat corpus cavernosum, their cumulative dose response curves (3×10(-7), 3×10(-6) and 3×10(-5) M) were determined in corpus cavernosum strips isolated from normal rats and pre-contracted with phenylephrine (3×10(-6) M) were also assessed. Results of this part showed that both yohimbine and sildenafil have a relaxant effect on rat corpus cavernosum strips in a dose dependant manner, which is confirmed by the increase in nitric oxide content in rats’ penis shown bysildenafil.

In the East, many herbal tonics and preparations are used to assist the aging male improve his sexual drive or ability to perform penetrative sex by increasing sexual stimulation, erectile, ejaculatory, orgasmic and other responses for sexual function and satisfaction. The herbs and tonics act as or as “pick-me-ups” and energizing tonics which help the tired and fatigued male and those with sexual asthenia. The myths and realities concerning Tongkat Ali, sea horse, cobra meat and blood, animal penises and testicles amongst many other herbs and portions for oral intake or local application used by traditional “medical” practitioners and village doctors will be discussed.
4. Jameel Mohd, Ansari Javed Akhtar, Ali Abuzer, Ahamad Javed, Ali M., Tamboli Ennus – Pharmacological scientific evidence for the promise of tribulus terrestris
The usage of plants, plant extracts or plant-derived pure chemicals for disease management, become a therapeutic modality, which has stood the test of time. In the present review, we focus on pharmacological profile (in tabular form) of Tribulus terrestris L., apart from Phytochemistry, Taxonomy and Traditional uses. Data were located, selected and extracted from SCI database, Medline, Pubmed, Highwire and Google Scholar. Fruits and seeds of Tribulus terrestris L., (Zygophyllaceae) are of immense importance in oriental medicine because they are used as an aphrodisiac, diuretic and anthelmintic, as well as to treat coughs and kidney failure. Tribulus terrestris L. has reported to have antimicrobial, antihypertension, diuretic, antiacetylcholine, haemolytic activity, spermatogenesis and libido enhancer, antitumor activity and effects on cardiovascular system. Furostanol and spirostanol saponins, flavonoid glycosides, alkaloids, steroidal saponins named terrestrosins A, B, C, D and E, F-gitonis, gitnin and amides have been reported to occur in Tribulus terrestris L. Traditionally T. terrestris is used in folk medicine as a tonic, aphrodisiac, palliative, astringent, stomachic, antihypertensive, diuretic, lithon-triptic, cordial drug and urinary anti-infective. The ash of the whole plant is good for external application in rheumatic-arthritis.

5. Saurabh Chhatre, Tanuja Nesari, Gauresh Somani, Divya Kanchan, and Sadhana Sathaye – Phytopharmacological overview of Tribulus terrestris
Tribulus terrestris (family Zygophyllaceae), commonly known as Gokshur or Gokharu or puncture vine, has been used for a long time in both the Indian and Chinese systems of medicine for treatment of various kinds of diseases. Its various parts contain a variety of chemical constituents which are medicinally important, such as flavonoids, flavonol glycosides, steroidal saponins, and alkaloids. It has diuretic, aphrodisiac, antiurolithic, immunomodulatory, antidiabetic, absorption enhancing, hypolipidemic, cardiotonic, central nervous system, hepatoprotective, anti-inflammatory, analgesic, antispasmodic, anticancer, antibacterial, anthelmintic, larvicidal, and anticariogenic activities. For the last few decades or so, extensive research work has been done to prove its biological activities and the pharmacology of its extracts. The aim of this review is to create a database for further investigations of the discovered phytochemical and pharmacological properties of this plant to promote research. This will help in confirmation of its traditional use along with its value-added utility, eventually leading to higher revenues from the plant.
6. A. Adimoelja – Phytochemicals: modern views and breakthrough in traditional herbal management of sexual dysfunctions
Traditional herbs have been a revolutionary breakthrough in the management of erectile dysfunction and have become known world-wide as an ‘instant’ treatment. The modern view of the management of erectile dysfunction subscribes to a single etiology, i.e. the mechanism of erection. A large number of pharmacological agents are orally consumed and vasoactive agents inserted intraurethrally or injected intrapenially to regain good erection. Modern phytochemicals have been developed from traditional herbs. Phytochemicals focus their mechanism of healing action of the root cause, i.e. the inability to control the proper function of the whole body system. Hence phytochemicals manage erectile dysfunction in the frame of sexual dysfunction as a whole entity. Protodioscin is a phytochemical agent derived from Tribulus terrestris L plant, which has been clinically proven to improve sexual desire and enhance erection via the conversion of protodioscin to DHEA (Dehydroepiandrosterone). Preliminary observations suggest that Tribulus terrestris L grown on different soils does not consistently produce the active component protodioscin. Further photochemical studies of many other herbal plants are needed to explain the inconsistent result found with other herbal plants, such as in diversities of Ginseng, Eurycoma longifolia, Pimpinella pruacen, Muara puama, Ginkgo biloba, Yohimbe etc.
7. Mrinalini Kumari, Praveen Kumar and Poonam Singh – Safety Evaluation of Tribulus Terrestris on the Male Reproductive Health of Laboratory Mouse
Tribulus terrestris (TT) has emerged as an instant plant for the treatment of sexual dysfunctions and fertility related disorders in the males. The present study was aimed to assess the safety efficacy of the fruit extract of TT on the male reproduction. Animals of Group I served as control while that of II and III were administered with 100mg/kgBW/day and 200mg/kgBW/day of the fruit extract of TT, respectively, for 28 days. Testicular histology, sperm parameters, serum clinical biochemistry (SGOT, SGPT and creatinine) and tissue biochemistry (fructose in the seminal vesicle, sialic acid in the epididymis, antioxidant enzymes activity, LPO, LDH and ALP in the testis) were carried out to establish the safety of the fruit extract. Safety of the extract was evidenced by the unaltered body weight and serum clinical biochemistry. Administration of the fruit extract of TT neither interfered with the weights of the reproductive organs nor altered the sperm indices in the cauda epididymidis as well as the spermatogenic activity in the testis. The unaltered androgen – dependent biochemical markers i.e. sialic acid in the epididymis and fructose in the seminal vesicle indicated the normal status of the testosterone level. Unaltered activities of testicular antioxidant enzymes and the level of LPO suggest that the fruit extract does not cause oxidative stress. Further the unaltered activities of LDH and ALP in the testis represent normal physiological activity of the organ that could be correlated with the uninterrupted spermatogenic activity. It can, therefore, be concluded that the fruit extract of this herb could effectively be used as a natural remedy in treatment of male reproductive disorders without causing any side effects.

Yohimbine hydrochloride, an alpha 2-adrenoceptor antagonist, was administered (3.3 mg/kg i.v.) to anesthetized normal dogs provided with a T-shaped catheter inserted in the ancreaticoduodenal vein. The effects on blood glucose levels and pancreatic hormones were investigated. We show that yohimbine induced an immediate and pronounced stimulatory effect on insulin secretionaccompanied by a clear decrease in blood glucose levels. Yohimbine also stimulated the pancreatic secretion of somatostatin and glucagon. However, the secretion kinetics were not the same for the three hormones: the stimulation was rapid and immediate forinsulin and somatostatin, whereas it was progressive for glucagon. All these stimulatory effects were suppressed by propranolol, thus implicating beta-adrenergic mechanisms. Bilateral cervical vagotomy markedly reduced the immediate effect of yohimbine on insulinsecretion, suggesting that a central neural pathway was implicated. In contrast, the progressive elevation in glucagon secretion was not decreased by vagotomy. Our results suggest that yohimbine stimulates, at least in part, insulin secretion by blocking central alpha 2-adrenoceptors.

Ginkgo biloba is among the most favourite and best explored herbal drugs. Standardized extracts of Ginkgo biloba represent the only herbal alternative to synthetic antidementia drugs in the therapy of cognitive decline and Alzheimer’s diseases. The clinical efficiency of such standardized Ginkgo biloba extracts (GBE) is still controversial, but authors of numerous international clinical studies recommended the use of GBE in the described therapies.Extracts of Ginkgo biloba are a mixture of substances with a wide variety of physical and chemical properties and activities. Numerous pharmacological investigations lead to the conclusion that the terpene trilactones (TTL) and the flavonoids of GBE are responsible for the main pharmacological effects of the extract in the therapy of cognitive decline. Therefore, the quality of GBE products must be oriented on a defined quantity of TTL and flavonoids. Furthermore, because of their toxic potential the amount of ginkgolic acid should be less than 5 ppm.However, data on pharmacokinetics and bioavailability, especially related to the central nervous system (CNS), which is the target tissue, are relatively rare. A few investigations characterize the TTL and flavonoids of Ginkgo biloba pharmacokinetically in plasma and in the brain. Recent investigations show that significant levels of TTL and Ginkgo biloba flavonoids cross the blood-brain barrier and enter the CNS of rats after oral application of GBE. Knowledge about the pharmacokinetic behaviour of these substances is necessary to discuss the pharmacological results on a more realistic basis.

This study was conducted on 30 consecutive male patients presenting to Kasr-Al Ainy Andrology outpatient clinic complaining of manifestations of partial androgen deficiency in aging males (PADAM). In this study (750 mg/day) of Tribulus terrestris in 3 divided doses, each of 250 mg, as an endogenous testosterone enhancer had been tried for a duration of 3 months and the evaluation of its effect had been monitored for each patient concerning its effect on serum testosterone (total and free) and luteinizing hormone (LH), as well as its impact on erectile function, which was evaluated by the International Index of Erectile Function-5 (IIEF-5) questionnaire for those patients. Results showed a statistically significant difference in the level of testosterone (total and free) and IIEF-5, but no statistically significant difference in the level of LH before and after treatment. Also, the study showed statistically significant correlation between testosterone (total and free) and IIEF-5, but no statistically significant correlation between the level of LH and the IIEF-5 before and after treatment.
11. Ganzera M1, Bedir E, Khan IA. – Determination of steroidal saponins in Tribulus terrestris by reversed-phase high-performance liquid chromatography and evaporative light scattering detection.
This paper describes the first analytical method suitable for the determination of steroidal saponins in Tribulus terrestris. A separation by high performance liquid chromatography (HPLC) was achieved by using a reversed-phase (RP-18) column, evaporative light scattering (ELS) detection, and a water/acetonitrile gradient as the mobile phase. The marker compound, protodioscin, was detected at a concentration as low as 10.0 microg/mL. Several different samples of plant material were successfully analyzed, and depending on origin and plant part used for extraction, significant differences in the composition of the saponins were observed. The analysis of market products showed considerable variations of 0.17 to 6.49% in the protodioscin content.
12. Dragomir Dinchev, Bogdan Janda, Liuba Evstatieva, Wieslaw Oleszek, Mohammad R. Aslani, Ivanka Kostova – Distribution of steroidal saponins in Tribulus terrestris from different geographical regions
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 T. terrestris collected in Bulgaria, Greece, Serbia, Macedonia, Turkey, Georgia, Iran, Vietnam and India were analyzed by LC-ESI/MS/MS 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 (1) and prototribestin (2) as main components. The Vietnamese and Indian samples exhibit totally different chemical profile. They lack 2 and 5, while tribulosin (6) is present in high amounts. Compounds different from 1 to 7 are dominating in these 3 samples. The presented results suggested the existence of one chemotype common to the East South European and West Asian regions. Most probably, the Vietnamese and Indian samples belong to other chemotypes which are still to be studied and characterized. No clear correlation between the burrs morphology and the chemical composition of the samples has been found.

Tribulus terrestris as a herbal remedy has shown beneficial aphrodisiac effects in a number of animal and human experiments. This study was designed as a randomized double-blind placebo-controlled trial to assess the safety and efficacy of Tribulus terrestris in women with hypoactive sexual desire disorder during their fertile years. Sixty seven women with hypoactive sexual desire disorder were randomly assigned to Tribulus terrestris extract (7.5 mg/day) or placebo for 4 weeks. Desire, arousal, lubrication, orgasm, satisfaction, and pain were measured at baseline and after 4 weeks after the end of the treatment by using the Female Sexual Function Index (FSFI). Two groups were compared by repeated measurement ANOVA test. Thirty women in placebo group and thirty women in drug group completed the study. At the end of the fourth week, patients in the Tribulus terrestris group had experienced significant improvement in their total FSFI (p < 0.001), desire (p < 0.001), arousal (p = 0.037), lubrication (p < 0.001), satisfaction (p < 0.001) and pain (p = 0.041) domains of FSFI. Frequency of side effects was similar between the two groups. Tribulus terrestris may safely and effectively improve desire in women with hypoactive sexual desire disorder. Further investigation of Tribulus terrestris in women is warranted.
14. Mameri Filho J, Haidar MA, Soares Junior JM, Baracat EC. – Effects of the association of estrogen and androgen in postmenopausal women. Rev Bras Ginecol Obstet (2005) 27: 118.
To evaluate the effects of the association of estrogen and androgen on the quality of life and sexuality of women during climacterium. Ninety-six postmenopausal women with vasomotor symptoms and sexual dysfunction were included. The participants were randomly divided into three treatment groups with 32 pacients each: placebo, conjugated equine estrogens (CEE) (0.625 mg per day) and CEE (0.625 mg per day) associated with methyltestosterone (2.5 mg per day). The length of the treatment period was three months. The Women Health Questionnaire (WHQ) and the Modified Sexuality Questionnaire were applied to evaluate the quality of life and sexuality before and after the treatment. Some parameters of cardiovascular risk, endometrial echo and hepatic toxicity were evaluated. ANOVA was used for data analysis followed by the Fisher test and the Shapiro-Wilk post hoc test. The improvement in WHQ parameters was significant in the hormonal treatment groups (CEE and CEE + methyltestosterone) compared to the placebo group. However, there were no differences in somatic symptoms among the three groups. The association of estrogen with androgen significantly improved sexual function (score (mean): 64 vs 67, p<0.05) and depressive humor (score (mean): 75 vs 80, p<0.05) compared to estrogen alone. This therapy also presented a large number of WHQ questions with a high score (p<0.05). The use of CEE associated with methyltestosterone decreased the total cholesterol (212±42 and 194±43, before and after the treatment, respectively) and HDL colesterol (56±16 and 48±14, before and after the treatment, respectively), and slightly increased the endometrial echo (4.7±2.3 and 5.5±2.3, before and after the treatment, respectively). No signifcant changes in liver enzymes during the treatment period was detected. Estrogen associated with methyltestosterone resulted in significant improvement in the quality of life and sexuality of postmenopausal women. This effect was superior to estrogen alone and placebo. The effect of treatment with the estrogen-androgen association was evident regarding depressive humor and sexual function questions of the WHQ.
15. K. Milasius, R. Dadeliene, Ju. Skernevicius – The influence of the Tribulus terrestris extract on the parameters of the functional preparadness and athletes organism homeostase
The influence of the Tribulus terrestris extract on the parameters of the functional preparadness and athletes’ organism homeostase was investigated. It was established the positive impact of dietary supplement “Tribulus” (Optimum Nutrition, U.S.A.) using per 1 capsule 3 times a day during 20 days on athletes’ physical power in various energy producing zones: anaerobic alactic muscular power and anaerobic alactic glycolytic power statistically reliable increased. Tribulus terrestris extract, after 20 days of consuming it, did not have essential effect on erythrocytes, haemoglobin and thrombocytes indices. During the experimental period statistically importantly increased percentage of granulocytes and decreased percentage of leucocytes show negative impact of this food supplement on changes of leucocytes formula in athletes’ blood. Creatinkinase concentration in athletes’ blood statistically importantly has increased and creatinine amount has had a tendency to decline during 20 days period of consuming Tribulus terrestris extract. The declining tendency of urea, cholesterol and bilirubin concentrations has appeared. The concentration of blood testosterone increased statistically reliable during the first half (10 days) of the experiment; it did not grow during the next 10 days while consuming Tribulus still.
