In the The Physic Garden, Gualdoni chronicles the transformation of plant material into medicine, bringing centuries old traditions and imagery to bear on contemporary quests for well being. Her paintings foreground pouring and staining techniques, inscribed with linear marks, made by pressing painted string onto canvas. This technique echoes engravings, woodcuts and drawings found in Medieval Herbals. The imagery in these paintings can coalesce and dissolve depending on a viewer’s focus, evoking the type of vision used in foraging for wild foods and medicines.

Gualdoni’s paintings embrace the fantastical, wishful and phantasmagoric aspects of homeopathy, positing that paintings can act as recipes or objects for healing.
