Milder temperatures, longer days and finally the sun’s return. After months of gloom and somewhat compelling news, the arrival the spring Sunday will do moral good. But the return of sunny days is also synonymous with the plight of millions of French Allergy for pollen. In the office of Dr. Michael Poliquin, an allergist at the St. Gregoire Clinic near Rennes, consultations for allergic rhinitis, commonly known as hay fever, have already begun. “Mainly for alder and ash pollen right now,” he says.
In the next few days, the peak of activity is expected with the first vaccine Birch, a very common delicacy. “Then there will be the weed period that runs from April to July and peaks at the end of May or beginning of June,” explains the allergist. In addition to the pollen sensors installed in the four corners of France, the profession has had a new tool for fifteen years to prevent this allergy. These are sentinel pollen plants that have appeared in many cities, especially in the Great West.
Real-time monitoring of pollen emissions
The Rennes, which opens to the public this Saturday with guided tours, has been installed since 2016 above Place Lucien-Rose, very close to Thabor Park. In this small garden, about fifteen plants common to the area, such as meadow foxtail, plantain tongue, and oak peduncle or hazel, were grown. “These are the species with the most sensitive pollen,” confirms Hervé Tiger, the gardener-botanist in Rennes and responsible for the pollen.
Every day, these plants are checked by gardeners to discover the beginning and end of the pollen release of each species. “We are thus closer to what happens in nature,” he says. Then the data is collected Via the pollen alerts website Which then takes care of alerting allergy sufferers and health professionals subscribing to our newsletter in near real time.
Only about fifteen animals are vaccinated in France
“It’s a very useful preventative tool because it allows the patient to know exactly when to start their treatment and when to stop it,” says Dr. Michael Poliquin, M.D., reference physician at Rennes pollinarium. The alerts also allow him to put together a very accurate pollen calendar each year, which helps him determine what allergies patients have. “It’s often very complicated because the pollen is overlapping,” he says. But depending on when the first symptoms appeared, we can identify the types that are most likely to cause the allergy.”
Valuable witnesses to pollen alert, pollen remains relatively unknown since there are only about fifteen cities. Dr. Poliquin hopes it “would be something good to develop everywhere.”
