10 mg vial of freeze-dried Ragweed extract.
Freeze dried extract of Ragweed (Ambrosia elatior) pollen. Ragweed is an annual plant that typically emerges in late spring and can grow up to 70 cm in height. The plant belongs to the genus Ambrosia and is native to North America, where it is commonly found in fields, along roadsides, and in other disturbed areas. Despite its unassuming appearance, ragweed is notorious for its ability to trigger allergies in sensitive individuals. The pollen of ragweed is a potent allergen that can cause a range of symptoms, including sneezing, runny nose, itchy eyes, and throat irritation. In some cases, exposure to ragweed pollen can also trigger asthma attacks or worsen existing respiratory conditions. Because ragweed pollen is so lightweight and easily airborne, it can travel long distances and affect individuals who live far away from the source plant. While ragweed is considered a nuisance by many people because of its potential to cause allergies, the plant does have some positive qualities. For example, it is an important source of food and habitat for a variety of insect species, including bees and butterflies. Additionally, some species of ragweed have been used in traditional medicine to treat a range of ailments, including fever, inflammation, and pain. Despite its potential to cause allergies, ragweed remains a common sight in many parts of North America, where it is an important component of the local ecosystem.
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. Each product will be delivered with a certificate of analysis. If you want to receive a certificate of analysis before ordering please let us know.
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.
