The method is the artisan one to produce very normal candles: a gas stove, classic tubes, glasses, pestle and mortar and rope for the wick. But the young Vitalis Kiplagat, on the outskirts of Nairobi, mixing wax with a mix of particular herbs, seems to have created the most powerful mosquito repellent candle in circulation.
As it happens for inventions that can mark an era or at least raise the bar of a certain area, the "recipe" is secret, but we know that one of these herbs wisely dosed by Vitalis is the Lantana Camara, a plant already known by international companies that sell the seeds to plant them in gardens and green spaces of areas particularly frequented by mosquitoes, even in Italy to keep away the fearsome "tiger". The other main ingredient are the leaves of a particular type of eucalyptus, the one known as "Tasmanian Bluegum Tree".
Vitalis told the Kenyan media that at the basis of his discovery there is a finding: attending high school, while the gardener set fire to the brushwood, he noticed that mosquitoes and other insects dispersed quickly only when certain plants were burned.
From there began the experiments that led to the creation of green candles that potentially keep away malaria, which still kills thousands of people every year in Kenya. Biological candles that passed the test and that now Kiplagat produces and sells to 50 shillings each, succeeding in producing at least one hundred by itself per day.
The preparation is not difficult: once the herbs have been ground, add a solvent in the ground powder to obtain a green solution, then immerse the rope in a green solution, with the wick that is then put in the solution of boiling wax to harden it.
The solution based on wisely dosed herbs is then added to the boiling wax and the whole is poured into the test tubes, to be cooled and solidified.
Finally, the same tubes are heated over a slow and constant fire to let out the candles thanks to the accumulation of pressure during heating.
An invention so successful, it seems, that the Kenya Medical Research Institute (KEMRI) is interested in the thing and is analyzing the composition to be able to transform the intuition of the Kenyan boy in a patent to be marketed in style.
