The Flowers of Icetor (boiled in spring water) were said to be the cure to Dryditch Fever, according to an old wives' tale referenced by Faith Spinney and Furgle the Hermit. Fortunately for the Redwall Abbey citizens afflicted with the illness, the wives' tale was right.
The flowers were small, delicate, starlike, with petals as white as snow and tinged with blue.
Thrugg, along with the Dibbun dormouse, Dumble, went questing north to successfully retrieve the flowers. The flowers grow only in the nest of Wild King MacPhearsome. While there, they met Wild King MacPhearsome, who helped them return to the Abbey very quickly.
The Flowers of Icetor appear in Salamandastron.
