A team of researchers led by Michel De Waard, Inserm Research Director at the Grenoble Institute of Neurosciences (Inserm, University Joseph Fourier, CNRS), has discovered that an African medicinal plant produces large quantities of molecules with analgesic properties. Even more surprising, analysis show that the molecule is identical to Tramadol, a wholly synthetic medication that is used world-wide as a painkiller. According to the research team, this is the first time ever that a synthetic medication produced by the pharmaceutical industry has been discovered in strong concentrations in a natural source. This unexpected discovery had just been published in the...

A cup of Brazilian mint tea has pain relieving qualities to match those of commercially available analgesics, a study suggests. Hyptis crenata has been prescribed by Brazilian healers for millennia to treat ailments from headaches and stomach pain to fever and flu. Working on mice, a Newcastle University team has proved scientifically that the ancient medicine men were right. The study is published in the journal Acta Horticulturae.

A NEW painkiller based on the venom of a sea snail will be available in Britain from today. Prialt, or ziconotide, is the result of more than 20 years’ research by a scientist born in the Philippines, Baldomera Olivera, who is a professor at the University of Utah. It is 1,000 times more potent than morphine but, unlike that drug, is not addictive. It is aimed at people suffering from severe, chronic pain who would normally require morphine. Given by injection into the fluid around the spine, it is the first non-opioid painkiller using this method of administration to be...

The lethal toxins produced by cone snails are in hot demand for neuroscience research, and are being developed as potent drugs. Laura Nelson visits a would-be snail ‘farmer’, for whom milking time is fraught with danger. 24 June 2004 LAURA NELSON This article is from the news section of the journal Nature Marine cone snails are among the most venomous beasts on the planet. © Nature Jon-Paul Bingham fumbles around for a condom.
