Chances are, you've seen energy drinks featuring guarana, but did you know that guarana is actually a plant native to the Amazon, with medicinal properties? Some say it's an over-stimulating, potentially dangerous caffeine product but is that true?
What is guarana?
Found in Venezuela and Brazil, guarana is a plant with seeds that have been used for centuries to boost energy levels and libido, while suppress appetite.
Also known as "paullinia cupana", guarana is now thrown into a range of food and beverages, including chewing gum and energy drinks. You can also buy it as a supplement over-the-counter.
It's important to note that guarana contains caffeine. Lots of it. And it's the caffeine that's attributed to the herb's stimulating properties. Although experts say the caffeine in the seeds is slow-releasing, providing ongoing energy unlike coffee.
Does guarana work?
Scientific opinion is divided on whether guarana is healthy or not – and whether its health benefits can be believed.
One recent study found no link between guarana and improved mood and wellbeing. Another trial highlighted that guarana supplements could improve mood.
And this ABC article cites a 2011 trial that suggested guarana could help treat fatigue in breast cancer patients – at least in the short term.
Then there's historical evidence, such as the Amazonia Indians using it to treat bowel problems, and diarrhea.
Is guarana safe?
Perhaps a more important question is whether guarana is safe to take. Some studies have provided evidence that too much guarana could cause kidney and heart problems, as well as seizures.
And because it's so high in caffeine (up to 80mg per gram), people taking certain medications such as blood thinning drugs and stimulants should avoid the herb. People with anxiety, ulcers, and diabetes are also warned against the stimulant.
Too much guarana, like coffee and other caffeine products, can result in insomnia, heart palpitations, anxiety, and dehydration.
If you are interested in trying guarana or other energy stimulants, chat to a herbalist. Then you can ensure you are getting the real deal, and not unknown amounts in a chemical concoction.
