Description

Freeze dried extract of Cypress (Cupressus arizonica) pollen. The Cupressus arizonica is a type of evergreen coniferous tree that has a conical shape and can grow as tall as 25 meters with a trunk diameter of up to 60 cm. It releases pollen during the period between February and March. This tree species is commonly found in dry, rocky slopes and canyons at elevations between 1,000 to 6,000 feet (300 to 1,800 meters) in the southwestern United States and northern Mexico. The bark of the Arizona cypress is grayish-brown and has deep furrows, while its scale-like leaves grow opposite each other along the stem. During the early spring season, the tree produces small, reddish-brown pollen cones at the tips of its branches, which shed great quantities of yellow-colored pollen, creating a fine dust that covers the surrounding area.

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.
