A Cup Of Brazilian Mint For Pain Relief

November 27, 2009

For thousands of years it has been prescribed by traditional healers in Brazil

to treat a range of ailments from headaches and stomach pain to fever and flu.

Now for the first time, researchers at Newcastle University have been able to

scientifically prove the pain relieving properties of Hyptis crenata - otherwise

known as Brazilian mint.

Testing this ancient South American herb on mice, the team led by researcher

Graciela Rocha was able to show that when prepared as a 'tea' - the traditional

way to administer the medicine - the mint was as effective as a synthetic

aspirin-style drug Indometacin.

The research was presented at the 2nd International Symposium on Medicinal and

Nutraceutical Plants in New Delhi, India, and will appear in the society's

journal Acta Horticulturae.

Now the Newcastle University team plan to launch clinical trials to find out how

effective the mint is as a pain relief for people.

Graciela explains: " Since humans first walked the earth we have looked to plants

to provide a cure for our ailments - in fact it is estimated more than 50,000

plants are used worldwide for medicinal purposes.

" Besides traditional use, more than half of all prescription drugs are based on

a molecule that occurs naturally in a plant.

" What we have done is to take a plant that is widely used to safely treat pain

and scientifically proven that it works as well as some synthetic drugs. Now the

next step is to find out how and why the plant works. "

What the study showed

In order to mimic as closely as possible the traditional treatment, the

Newcastle University team first carried out a survey in Brazil to find out how

the medicine is typically prepared and how much should be consumed.

The most common method was to produce a decoction, a process whereby the dried

leaves are boiled in water for 30 minutes and allowed to cool before being drunk

as a 'tea'.

The team found that when the mint was given at a dose similar to that prescribed

by traditional healers, the medicine was as effective at relieving pain as the

Indometacin.

Graciela, who is herself Brazilian and remembers being given the tea as a cure

for every childhood illness, adds: " The taste isn't what most people here in the

UK would recognize as a mint.

" In fact it tastes more like sage which is another member of the mint family.

Not that nice, really, but then medicine isn't supposed to be nice, is it? "
