Nymphaea caerulea, known primarily as blue lotus (or blue Egyptian lotus), but also blue water lily (or blue Egyptian water lily), and sacred blue lily, is a water lily in the genus Nymphaea. Like other species in the genus, the plant contains the psychoactive alkaloid aporphine (not to be confused with apomorphine). It was known to the Ancient Egyptian civilizations.

The blue lotus high provides a sense of tranquillity and euphoria, along with an altered sense of awareness. Its effects famously combine very well with wine, which illuminate the social and euphoric aspect. Or, you can take the blue lotus alone and concentrate on its ability to enhance meditative and introspective practices.

Some users also report a pleasant feeling of warmth around the head and upper body and a dream like feeling – as if the life itself were a waking dream.

It can be added to wine or vodka, made into a tea, or smoked.
