An extract prepared from the pollen of various Swedish flowers, often including plants from the Passiflora genus (passion flowers).

The extract is said to reduce the size of the prostate, restoring sexual function in older men with enlarged prostates. Some supplement manufacturers also claim that Swedish flower pollen has antioxidant and cholesterol-lowering effects.

Several clinical studies have supported these benefits in specific preparations, although it is important to note that manufacturers may use different types of pollen sources when preparing their products.
