An African bark extract studied since the 1960s for nighttime urinary comfort.
Pygeum Africanum (Prunus africana) is a large evergreen tree native to sub-Saharan Africa. Its bark extract has been used in traditional African medicine for urinary complaints for centuries, and has been the subject of controlled research since the 1960s.
The bark is rich in phytosterols, pentacyclic triterpenoids and ferulic acid esters. One of its most studied areas is nocturia — waking during the night to urinate — one of the most quality-of-life-affecting symptoms tied to prostate enlargement in older men.
FlowStrong includes Pygeum specifically for this nighttime comfort angle, complementing Saw Palmetto's daytime urinary flow focus.
