It may seem unlikely that reducing the number of allergenic plants in a single garden would make a difference to a sufferer of allergic disease. Nonetheless, it is important to limit the spread of allergenic plants because a collective effort by as many of us as possible could have a real impact on the levels of pollen in our atmosphere. Eliminating allergenic plants close to dwellings can reduce symptoms of occupants who have allergic respiratory disease. We are planting new allergens.
