Description

Freeze dried extract of Ribwort (Plantago lanceolate) pollen. Ribwort, also known as Plantago lanceolata, is a common weed that can often be found growing on cultivated or disturbed land. While its native range is Eurasia, it has been introduced to many other parts of the world where suitable habitats exist, including North America. Despite its status as a weed, ribwort has a number of interesting characteristics that make it a valuable plant in its own right. It is a perennial herb that can grow up to 60 cm in height, and it has long, narrow leaves that taper to a point. The plant produces numerous small, brownish flowers that are arranged in spikes, and these flowers are a rich source of nectar and pollen for bees and other pollinators.

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.

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.
