FWIW, I have personally tried Tribulus Terrestris and if made me feel foul. I only took for about a week and then returned it. I remember the symptons as having an increased heart rate and had difficulty sleeping.

From my understanding, Trib has an impact on luteinizing hormone. It stimulates the Leydig cell production of testosterone. However, messing with your body's normal levels can foul up the natural production of T so that you no longer produce a decent level without the artificial help. Stick with good food and exercise which naturally stimulates testosterone and growth hormone production.

I don't know that I would do it. Yes, herbs can provide all sorts of benefits. However, there's a couple things to watch out for when using these things for medicinal purposes. They're natural plants, so there's natural variations in the active ingredients. You don't know what you're really getting when you take it. Next, it's in the wild. You don't know what's been sprayed on it in the past, or if there's anything bad leeching in the soil.

That's why the pharmaceutical industry is so big (well asides from all the negative stuff about the "evil" RX companies). They identify the active ingredients, test and standardize the amounts, identify side effects, overdosing symptoms, etc.

The Chinese and the Indians have been using it for thousands of years, mostly for making tonics to invigorate the human body. The Tribulus Terrestris fruit is a part of treatment for of a variety of health problems connected to the immune system, liver, kidney, and cardiovascular system. The Tribulus Terrestris fruit has antioxidant properties and some studies have been done on the liquid extract of Tribulus Terrestris fruit to establish the facts.

I have been taking it for awhile and it defiantly helps increase mood, boost strength, and defiantly increases your chances of being a gladiator in the bedroom. Boosting testosterone from diet alone is possible, if you went "true paleo", and ate the fatty meats a lot, and not just lean, like cavemen actually did. However we are smarter and understand the problems with high cholesterol. Trib is safe and effective if needed if you are in you mid to late 30's-40's and up and your test levels are down. Younger guys bodies are still pumping it out naturally. If it makes you feel to aggressive and moody, then you levels were probably fine and don't need it. If it makes you feel good and happy and strong like when you were younger, then your levels were probably lower and you benefit from it. check with your primary care physician first, and see what they say. I work in surgery and ran it past many different MD's and my PCP before I started, and got the green light from them. My PCP said it's natural and safe, and you would have to take a lot of it to do any harm long term and is a safe alternative to try first for guys with ED.

Just my two cents on it. I did a lot of checking and research before doing it myself and have had no problems. On a side note, take it with food. On an empty stomach can make you feel a little weird.

Personally, I have a hard time believing that an herbal supplement could have a positive effect on overall health unless it contained a particular nutrient that you happened to be deficient in. The pharm/supp magic pill syndrome seems to me to be the wrong approach to health, even if you are picking the sources wild.
