White Water Lily - Best Herb for Blood Pressure

White & yellow water lily

Nymphaea alba, Nuphar luteum Nymphaeaceae


Both white and yellow water lilies are aquatic with floating leaves, submerged stems and rhizomes that anchor them to the pond floor. They have sweet-smelling flowers and large, long-stalked leaves. The white water-lily flower grows to a diameter 12cm, while the yellow water-lily flower is 4-5cm across.


Parts used

  • Rhizome {both}: flowers {white water lily}
  • The flowers and rhizomes {lifted when dormant} are dried and used for infusions and decoctions.

Constituents

The rhizomes contain sesquiterpenoid alkaloids {nupharine, nymphaeine, nuphacristine, thiobinupharidine}, astringent tannins, flavonoids and vitamin C.


CAUTION

White water lily is best taken as directed by a medical herbalist as excessively high doses over a long period of time could cause an irreversible loss of libido.


Medicinal uses

The white water lily has sedative properties and relieves diarrhoea and intestinal inflammation. It is also able to reduce blood pressure.


The yellow water lily, traditionally known as the 'destroyer of pleasure and poison of love', has long been used in potions and cordials intended to reduce sexual desire and send the imbiber to sleep. In fact both white and yellow water lily share this ability to calm the libido.


The plants are used to treat inflammation of the skin, mouth and throat, and to treat catarrh. Yellow water lily is also prescribed to treat vaginal discharge and fungal infections. Studies published in The Journal of Pharmaceutical Sciences in 1973 verified the antifungal activity of the plants, attributing it to a sesquiterpenoid alkaloid found in the rhizomes.


Cultivation

Submerge in water up to 45cm deep and plant in moist. nutrient-rich soil.
