guarana fruit

GUARANA

 

Guarana is a vine with compound leaves and flowers in bunches. The fruit (capsule) is small, red and contains a seed inside. This is a shrub native to the Amazon, found in Peru, Brazil, Colombia and Venezuela. Its scientific name is Paullinia cupana and belongs to the Sapindaceae family.

The genus is named Paul linia by Linnaeus in honor of Simon Paulli, a German botanist. In Brazil it is grown in the state of Amazonas and Bahia. In the region near the town of Maués, where it is cultivated, the Indians of the nation Sateré-Mawé have legends about the origin of the plant.

Guarana plays an important role in the culture of the Brazilian Tupi Guaraní. Guarana is a name derived from the word "wara" ná "in Tupi-Guarani means" fruit like the eyes of the people. "These tribes believed that the fruit was magic to cure intestinal diseases and a way to regain strength. They also believe in the myth of the "Divine Child" who was killed by a snake and his eyes gave life to this plant.

 

EFFECTS AND USES

Unlike coffee, Guarana is not nervous but acts as reanimarte and
Refreshes the body and mind. Its component caffeine (also called guaranine) for its high content in tannins and fibre, is absorbed slowly and gently through the body.

Often criticized the high percentage of caffeine, 3.5%, which is in 100g of Guarana powder. But do not pay attention to the fact that there are those who eat 100g, but 1 g of powder per serving and it contains only 40 mg of caffeine, while a cup of coffee has 80mg. Everything depends on the amount ingested .

2 I am apparently quite allergic to this Guarana. I wonder if my case is unique. First time I had it was 17 years ago in a soft drink called Josta which I donīt think they make anymore. It caused me to have a panic attack where I felt severe angina (chest pain) and like I couldnīt breathe. Since then I have avoided it and I do not use "energy drinks". Most nowadays contain guarana. I am aware that I am somewhat caffeine sensitive but I still drink coffee on a semi-regular basis in moderation. I notice there is some difference in the intensity of effects of various caffeinated drinks besides coffee such as Black and Green Tea, Yerba Mate, and Guayusa. However I hav never experienced the intense adverse effects that I got from guayusa with other caffeine sources, so I think there must be something uniquely different about its form of caffeine and or accompany alkaloid profile which is different from coffee and teas. I just used a couple of herbal energy tablet over the past two days in a split dose fashion. I was aware that the pills contained guarana as one of their component extracts. It said that one pill only contained 60 mgs of caffeine of which the guarana was only one component along with green tea, and yerba mate extracts. I had one of two sample tablets yesterday and the day before. The effects were the same; collapse of my autonomic respiratory function(found myself not breathing) combined with extreme angina and overall tiredness. I do not like guarana. I beleive I am allergic to it. I will not use it anymore for the rest of my life if I can help it.
