Already, kisses to trees that have not asked anything by gripping them with strong feelings and stay like that tenderly, forehead pressed against his trunk that gives off the good vibe, it's a little grotesque. But hey, not so much more than any practice of "reconnecting" with nature (the simplest still being to live in the countryside). But here is Science and the Future, the science magazine (who knows what he says unlike some gurus who make people fool around to fiddle with trunks) drops a bomb in the open country: "Kissing a leafy or a conifer is not safe! The embrace, especially if it is practiced in shorts and short sleeves, may turn short as the trunks are home to many perils irritating, stinging … even fatal. "Yes, you have five minutes to sneer.
And so why would it be dangerous? Because, explains Christophe Bouget, researcher at the EFNO Forest Ecosystems Laboratory of the National Institute for Research in Science and Technology for the Environment and Agriculture of Nogent-sur-Vernisson (Loiret), quoted by the magazine, there is potentially in oak bark or charms for example, "a frullania, a foam that causes severe itching that may extend beyond areas of the body that have been affected."
Blisters, inflammation, swelling
In fact, we have never seen a logger engage in this kind of practices, they are well aware that frullanolide is an allergen responsible for allergic contact dermatitis. And the magazine to put a layer of leaves over: in a publication of the National Institute of Research and Security Cochin hospital, a dermatologist points a farandole of allergenic substances that can cause violent reactions, some also being " in the lichens of the genus Evernia, Parmelia, Cladonia or Usnea, which grow in particular on the oak trunks and produce highly allergenic acids ". In Quebec, the authorities recommend to wash very quickly if contact, otherwise it is blisters, inflammation, swelling etc.
Without mercy for the future of the silturotherapists, Sciences and future then attacks to the mancenillier, who nevertheless looks harmless. The air of a tree, what? " A member of the Euphorbiaceae family, he produced an extremely toxic latex that earned him the nickname" tree of death ". Wherever he is, tourist offices recommend not sheltering under his branches in case of rain because the runoff of his sap certainly causes burns. "And I do not charge you this bastard of pine processionary caterpillar, for example, whose small stinging hairs are lodged on the skin, causes itchy itching, "releases thaumetopoein, a toxin that intrudes into the body. The substance can then cause edema and – in 2 to 3% of cases – cause an anaphylactic reaction according to INRA ", that is to say a major allergic shock may be life-threatening. All this for a walk in the forest, plus the ticks that can get caught (Lyme disease), it's a little thinking about the next outing in the forest of Chantilly.
Frelons and mambas
With that, the magazine reminds that a tree can also shelter a nest of hornets or in some parts of the world (but not in Chantilly) the formidable black mamba, one of the most venomous snakes of the earth. In short, silvotherapy takes a hit on the limb. While the sites promise "to manage nervous stress gently, to take care of oneself and others in a 100% natural way, to connect with nature, trees, the tree that is in us and in our nature … " You excuse me, but I do not have a tree in me and finally I hate nature.
