Typha angustifolia Pollen Source & Identity
The botanical entity is Typha angustifolia L., a tall marsh plant of the cattail family, Typhaceae, common in wetlands of the northern hemisphere. The part used is the pollen, a fine yellow dust shed from the male flower spike that sits above the brown female spike. Leaves, rhizomes and the spike itself are not part of this cattail pollen extract.
Pollen from other sources is a different material. Bee pollen is collected by honeybees from many flowers, pine pollen comes from Pinus, and the broad-leaved cattail, Typha latifolia, is a related species. Chinese pharmacopoeial texts accept pollen from T. angustifolia, T. orientalis and other plants of the same genus as puhuang.
Flavonoids, including isorhamnetin and typhaneoside, together with polysaccharides and sterols, are the constituent families of the pollen.
