Negative Effects of Tribulus Terrestris

Tribulus terrestris is a flower most often found in Europe, Asia, Australia and Africa. While eaten for centuries by livestock, it's most commonly used in herbal supplements as an aphrodisiac and for erectile dysfunction. While generally considered safe in small doses, if ingested in larger quantities, it can lead to certain side effects.

Liver Problems

While not likely to be found in humans, when ingested as about 80 percent of their diet, livestock were found to exhibit signs of liver damage.

Restlessness

Tribulus terrestris is a stimulant and can cause increased energy in doses above 500 mg. This can also lead to restlessness.

Elevated Heart Rate

Another side effect of its stimulating properties is an elevated heart rate. While the elevation is usually minor, it can be noticeable, especially while resting.

Increased Blood Pressure

Increased energy and heart rate can contribute to a sudden spike in blood pressure. Though not life-threatening, you should keep an eye on it and make sure it goes back down after the effects of the supplement wear off.

Warning

When taking any new drug or supplement, it is a good idea to first see a physician. While harmless at first glance, there may be side effects and drug interactions that you should be aware of.
