Description
What is Tribulus Terrestris Extract?
This herb has been traditionally used for centuries by the Greek, Chinese and Indian cultures for a variety of health concerns.Tribulus Terrestris may enhance the production of the luteinizing hormone (LH). When LH levels are increased, the natural production of testosterone is also increased. LH is a hormone that also enhances sex drive and libido. Tribulus Terrestris may help enhance testosterone production promoting improved muscle growth and overall body strength.
Proerectile pharmacological effects of Tribulus terrestris extract on the rabbit corpus cavernosum.
The objective of the present study was to investigate the effect of oral treatment of Tribulus terrestris (TT) extract on the isolated corpus cavernosal tissue of New Zealand white (NZW) rabbits and to determine the mechanism by which protodioscin , a constituent of the TT, exerts its pharmacological effects. 24 rabbits were randomly assigned to 4 experimental groups of 6 each. Group I served as control. Groups II to IV were treated with the extract at different dose levels, i.e. 2.5 mg/kg, 5 mg/kg and 10 mg/kg body weight, respectively. The TT extract was administered orally, once daily, for a period of 8 weeks. The rabbits were then sacrificed and their penile tissue isolated to evaluate the responses to both contracting and relaxing pharmacological agents and electrical field stimulation (EFS).
Tribulus terrestris extract:
Tribulus terrestris herb, also called "puncture vine" is a plant long used around the world for the treatment of various ailments. Tribulus terrestris is popularly claimed to improve sexual function in humans. In Europe tribulus terrestris herb has been used in folk medicine throughout history, as far back as the Greeks, treating such wide-ranging conditions as headache, nervous disorders, constipation, and sexual dysfunction. In China and India, tribulus has been touted for use in liver, kidney, urinary, and cardiovascular remedies.
Tribulus Terrestris Extract: Supplement Fact or Fiction:
The original purpose for tribulus terrestris extract was as a "tonic" to treat sexual dysfunction. In animal husbandry studies tribulus extract was shown to stimulate rutting behavior (i.e. attempting to score) in rams as well as boars. When the supplement Tribestan was given to healthy men (Milanov, 1981) in a dose of 750 milligrams per day for five days, LH and testosterone were elevated 72% and 40% respectively. As you might expect, estradiol was also elevated. In fact estradiol was elevated by 81%. The increase in testosterone is obviously what all the fuss is about, nevertheless, you can’t ignore the fact that whenever you increase testosterone you are going to increase aromatization and therefore estrogen levels. To put these changes in hormone levels into perspective, the reference range for testosterone in men is between 300 - 1,000 ng/dL. The subjects in this study started out with an average of 600 ng/dL and ended up with about 850 ng/dL. This is still well within the "normal" range for men. Estradiol on the other hand went from normal levels of about 76 pg/ml to significantly elevated levels of 137.5 pg/ml. This is well above normal levels which range from about 20-80 pg/ml in men.
