For thousands of years scientists are still shrouded in mystery about how the ancient corpses on the island of Sardinia on average in the smiling face condition. Scientists Reveal Mystery smiling corpse corpse corpse Smiling As National Geographic reported on Thursday (4 / 6) now after 2800 years have passed, they managed to reveal that there is plant material that is able to make people smile on his deathbed. This plant could be expected to make an appearance like a smiling face of the corpse. Previously, the author of the 8th century BC, Homer never mentions the term word "smile Sardonik" taken from the root word "Sardinia" in a number of his writings refer to ritual murders on the island that ended with a smiley face. According to recent studies, older people in the past that allegedly have no longer survive and those involved in criminal cases "sardonik fed with herbs and then killed by being dropped from a high hill or beaten to death". For centuries herbs identity remains a mystery. However, a study led by Giovanni Appendino colleagues managed to uncover the content of herbs that can make the people who will die of it smiling at a plant called hemlock water-dropwort. White flowering plants such as these rods grow along the ponds and rivers in several parts of the country of Italy. About a decade ago, a Sardinian shepherd committed suicide by consuming plant hemlock water-dropwort so that his body was found in a state of smiling. Death makes Mauro Ballero, botanists at the University of Cagliari in Sardinia to investigate further any dropwort plants on the island. His research was continued by Ballero and colleagues who examined the structure of plant toxin molecule hemlock water-dropwort and determine their impact on the human body. Appendino, an expert in organic chemistry at the Universita degli Studi del Piemonte Orientale in Italy explains, "The content is very high toxin and causes the symptoms are exactly the same as those described in ancient records and relics sardonik smiling corpses." Dikatakanya, hemlock water-plant dropwort is known to contain a neurotoxin and we think that's what plants people used to wear. "In addition to plant hemlock water-dropwort, there are also other plants are hairy buttercup (aka the Sardinian buttercup). However, these plants do not grow in damp places as mentioned in several ancient texts, and also does not contain a powerful toxin, clearly Appendino. He added that Sardinia is the only place in the entire Mediterranean vegetation types hemlock water-dropwort. According to a relative of the deceased victim, hemlock water-dropwort plants are very dangerous due to the smell and the taste is very sweet. "In general it is bitter but poisonous plant hemlock water-dropwort has a sweet taste. And this is the second case of toxic plants that can stimulate our senses. According Appendino, this plant is very useful for cosmetics because it can relax the muscles and eliminate wrinkles, wrinkles on the face. Their findings were presented in the Journal of Natural Products.
