5 mg freeze dried extract of Birch (Betula Pendula) pollen. Belonging to the Betulaceae family, birch trees are closely related to the Fabaceae family, which includes popular plants like beans and peas. As a deciduous hardwood tree, the birch stands out for its delicate, thin leaves, which form a triangular or diamond shape. Their bark is equally distinctive, with fairly long, horizontal lenticels that provide a unique texture to the tree’s appearance. Birch trees can grow up to 25 meters in height, with a trunk diameter of around 40 centimeters. During the early months of the year, typically between February and April, the trees release their pollen. This pollen is wind-pollinated, meaning it can be carried great distances by the wind. Unfortunately, for many people, birch pollen is highly allergenic, causing a range of symptoms such as sneezing, runny nose, itchy eyes, and even asthma attacks.
Despite the potential allergenic properties of birch pollen, the tree itself is a vital component of many ecosystems. It provides food and habitat for a wide variety of animals, including birds, insects, and mammals. Additionally, its wood is used for a range of purposes, from furniture and paper production to firewood and even toothpicks. Raw material was cultivated in Middle Europe by collecting branches of trees and put in a greenhouse until the inflorescences matured. After maturing the inflorescences were collected, sieved and extracted with acetone. The pollen have been extracted followed by filtration. They have been freeze dried after dialysis.
Pollen is one of the most common triggers of seasonal allergies worldwide. Depending on the season, weeds, grasses and trees release pollen to fertilize their own species. The wind travels the tiny and light pollen but unfortunately they end up in our noses, eyes and lungs as well.With their powdery, granular appearance they look quite delicate and innocent. In some people they will however trigger an allergic reaction. We mostly relate to this as hay fever. Most common symptoms are a runny nose, sneezing, itchy eyes but sometimes also symptoms of the lower airways (asthma). In allergy-prone individuals, their immune system reacts to allergenic proteins by generation of IgE antibodies, a process called sensitization. These antibodies will bind to receptors on mast cells and basophils, the effector cells of allergic diseases. If a pollen-sensitized person then gets exposed in pollen season, these effector cells release various mediators such as histamine. These mediators together are at the basis of starting off the allergic symptoms.
