Grass of Parnassus

Parnassia palustris

Despite its name, grass of Parnassus is not a grass at all, but a solitary wetland wildflower that has quietly threaded through European folk medicine for centuries. Old herbals, including those of the Scottish Highlands, describe the fresh plant being used for troubled eyes and the dried herb brewed into a decoction for jaundice and sluggish liver complaints. It earned its poetic name from writers who linked it to Mount Parnassus in Greece, home of Apollo and the Muses, lending an almost sacred air to a humble bog flower. By the time of Renaissance herbalists like Gerard, it had settled into cottage medicine as a gentle, unassuming remedy rather than a dramatic cure.

Traditional preparations.

Traditional Liver Tonic Tea

In old European herbal practice, the dried herb was brewed into a mild tea and taken occasionally as a gentle traditional support for the liver and digestion.

Traditionally, a scant teaspoon of the dried herb is steeped in 250 ml of just-boiled water for 8 to 10 minutes, then strained and sipped, no more than once daily.

Safety.

Grass of Parnassus tea should be used only occasionally and in modest amounts, and avoided during pregnancy, breastfeeding, or with liver or kidney conditions. Its traditional use as an eye rinse isn't recommended today, since homemade preparations risk eye irritation or infection.
