Description

Tribulus terrestris has the prostate, flat stems radiate from the crown to a diametre of up to a metre. They grow in horizontal patches unless growing in shade where they tend to grow taller. T. terrestris produces flowers that are mesuaring 5mm to 10mm wide with yellow petals. The flowers produce a fruit that is composed of four or five sections or nutlets which have sharp spines. The carpals of the fruit resemble the cloven hoof of a cow.

Origin / Habitat

T. terrestris is a flowering annual found widely throughout India at elevations up to 5,400 metre. It thrives in warm and tropical areas of the world and can grow in desert conditions and sandy soils. It can also grow as a summer annual in colder climates.

Chemical Constituents

Terrestrosins A, B, C, D, E; alkaloids; Sterols including Beta-sitosterol, campesterol, stigmasterol; flavinoids; terrestiamide, tannins, tribol, spirostanol saponins [1][2][3].

Plant Part Used

Fruit and root. Occasionally the stem is used as an astringent [4].

Traditional Use

In the variety of African traditional medical systems, the most concentrated usage of T. terrestris occurs in the Central Saharan region of the continent. Most commonly, it is the fruit of T. terrestris that is used in its various applications. As it is throughout the rest of its natural habitat, one of the most common uses of T. terrestris is that of an aphrodisiac. In Algeria, one popular application of T. terrestris as an aphrodisiac is an infusion of the fruit ingested [4]. In West Africa, it is more common for the fruits to be ingested alone to achieve the same effect [4].In other cases, the whole plant is decocted and ingested [5]. In cases of certain sexually transmitted diseases, namely gonorrhea, the roots are boiled in water, and then ingested throughout the day [6].

Another very common usage of T. terrestris is as a gastrointestinal aide. In cases of diarrhea, the leaves and twigs are often used to alleviate symptoms. In some cases, leafy twigs are macerated and combined with herbs into a sauce which is eaten with meals [5]. In other cases, a leaf tea is ingested [4]. T. terrestris is also considered in some African traditional medical systems to be a very effective diuretic. Fruit extracts of T. terrestris have been used and thought to be both diuretic and stimulant [7].

Pharmacology

Pre-clinical

T. terrestris has been found in laboratory studies to possess antifungal and antibacterial properties. In one study this herb was tested against 11 species of pathogenic and non-pathogenic microorganisms. Extracts from all parts of the plant were tested and all demonstrated antimicrobial activity against most of the 11 organisms. Of the plant parts tested, the most active against both Gram-negative and Gram-positive bacteria was ethanol extract from the fruits. This same extract also demonstrated anti-fungal activity against C. albicans [8]. An in vitro study examined the anti-fungal activity of eight saponins from T. terrestris against six fluconazole-resistant yeasts. The results demonstrated effective antifungal activity for two of the saponins (TTS-12 and TTS-15) against several candidal species [9]. Additional research has supported these findings [10].

Research has continued into the cytotoxic properties of T. terrestris against several types of cancer cell lines. One of the active principles of this herb, spirostanol glycoside, demonstrated a broad range of anticancer activity against multiple areas [10]. In one study, saponins from T. terrestris were examined against liver cancer cell lines. The saponins demonstrated cytotoxic activity against the liver cancer cells through apoptosis [11]. In an in-vitro study, saponins were examined against renal carcinoma cells and again, the results indicated that the saponins decreased the number of cancer cells though apoptosis [12]. The method by which this action takes place is thought to involve up- and down-regulation of polyamines' homeostasis, suppression of proliferation, and inducing apoptosis [13].

T. terrestris is also often used in the treatment of hypertension [14] and in heart disease. In one fairly large study of over 400 patients with coronary heart disease, saponins from T. terrestris demonstrated the action of dilating coronary artery and improving coronary circulation and demonstrated more positive effects on improving ECG of myocardial ischemia than patients in a control group taking Yufen Ningxin Pian. Researchers concluded that this herb has the potential to be an ideal treatment for angina pectoris as it produces no adverse side effects on hepatic and renal functions even when taken over a long period of time [15].

T. terrestris is also used as anaphrodisiac, primarily in males [16] and, due to its ability increase certain sexual hormones, it has been used in mild cases of erectile dysfunction [17].

Clinical

T. terrestris is also marketed as a dietary supplement to improve endurance and strength during exercise. Not only has this not been substantiated, but there have been numerous studies that have shown negative results for this application [18][19]. There have also been reports of increased incidence of gynaecomastia in male body builders [20].
