Pine pollen comes from the male cones at the end of lower branches. Relative humidity, wind, moisture and health of the male cone all make a difference. Dry, warm, sunny days open the cone and spread the pollen. Also global warming has found that allergy season is affecting more people and lasting up to 27 days longer than it has in the past. Some research has suggested that the warming trend that we have in our environment is causing the pollen seasons to start a little bit earlier and extend a little bit longer. Pine pollen powder, which is dispersed by the wind, generally within 300 feet from the original tree. To determine when the pine pollen season will begin and when the trees will be producing the maximum amount of pollen one needs to estimate the number of degree-days above 55 Fahrenheit after February. Pine Pollen has been identified as a component of medicines that are 2,000 years old. Itâs believed that pine pollen has anti-aging properties, alleviates fatigue, and boosts testosterone.
