Female plants, especially trees, are natural air cleaners. According to Ogren this is because the flowers on female trees are positively charged and airborne pollen is negatively charged. This makes the two mutually attractive, and removes allergy-causing pollen out of the air. Critics of Ogren's theory say that pollen knows no boundaries and can blow in from just about anywhere. And while Ogren concedes that some pollen does blow in from far way, the majority of the pollen falls close to where it originates.
Gravity affects everything- including pollen.
According to Ogren, allergy is often very localized. For example, frequently cases of allergy are seen where people have male shrubs of species such as Yew or Juniper planted right under bedroom windows. Pollen is tiny and can easily pass right through the tightest window screens. All Rights Reserved. Straight Goods respects the intellectual property of our contributors.
