Timothy Grass extract
10 mg vial of freeze dried Timothy Grass extract.
Description
Freeze dried extract of Timothy Grass (Phleum pratense) pollen. Timothy grass is a tall, hardy, and cool-season perennial grass with cylindrical flower heads that can reach over a meter in height. This grass species is widely distributed throughout the temperate regions of the world and is native to most of Europe, except for the Mediterranean region. It is commonly found in meadows, pastures, and other open grasslands. Timothy grass is an important forage grass that is widely used for hay, silage, and pasture. It is highly palatable to livestock and provides excellent nutrition, with high levels of protein and digestible fiber. The flowering period of timothy grass is typically from June to August, with the seed heads turning a distinctive purplish-brown color as they mature. This grass species is wind-pollinated, and the pollen can cause hay fever and other allergic reactions in sensitive individuals. However, despite its allergenic properties, timothy grass plays a critical role in supporting a diverse array of wildlife, including insects, small mammals, and birds.
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.
Additional information
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.
