History & Folklore

William Withering, the 18th-century doctor who discovered the cardiotonic effects of foxglove (Digitalis purpurea), recommended a teaspoon of dried leaves to be taken at 3-hour intervals to assuage bouts of malarial fever.

Medicinal Actions & Uses

Silverweed’s main medicinal value lies in its astringent and anti-inflammatory activity. It makes an effective gargle for sore throats, and is a helpful remedy for diarrhea. Less astringent than its close relative tormentil (P. erecta), it also has a gentler action within the gastrointestinal tract. It is used externally as a lotion or ointment for bleeding hemorrhoids.


Use internally for more no more than 3–4 weeks at a time.
