Nymphaea alba, also known as the European white water lily, white water rose or white nenuphar, is an aquatic flowering plant of the family Nymphaeaceae. It is native to North Africa, temperate Asia, Europe and Tropical Asia (India).

It grows in water that is 30–150 cm (12–59 in) deep and likes large ponds and lakes.
The red variety (Nymphaea alba f. rosea) is cultivated from lake Fagertärn ("Fair tarn") in the forest of Tiveden, Sweden, where they were discovered in the early 19th century. The discovery led to a large-scale exploitation which nearly made it extinct in the wild before it was protected.

It contains the active alkaloids nupharine and nymphaeine, and is a sedative and an aphrodisiac/anaphrodisiac depending on sources. Although roots and stalks are used in traditional herbal medicine along with the flower, the petals and other flower parts are the most potent. Alcohol can be used to extract the active alkaloids, and it also boosts the sedative effects. The root of the plant was used by monks and nuns for hundreds of years as an anaphrodisiac, being crushed and mixed with wine. In the earliest printed medical textbooks, authors maintained this use, though warning against consuming large and frequent doses.
