Pellitory (Parietaria officinalis), also known as pellitory-of-the-wall, has a long history of traditional use in herbal medicine. In the context of injuries, its application is primarily rooted in folk medicine rather than supported by scientific research. Historical texts and traditional herbalists have recommended pellitory as a poultice or topical application for minor wounds, bruises, and inflammations, attributing to it soothing, anti-inflammatory, and healing properties. These uses were likely based on empirical observations and the doctrine of signatures popular in pre-modern herbalism.

However, contemporary scientific literature provides little to no evidence to validate pellitory's efficacy for supporting or treating injuries. Pharmacological studies on pellitory have focused more on its diuretic and anti-urolithic (kidney stone prevention) properties, with only limited investigation into its effects on wound healing or tissue repair. As such, while pellitory continues to be listed in some herbal compendia for topical use on injuries, its support rests almost entirely on historical and traditional precedent rather than modern scientific validation.

In summary, pellitory’s use for injuries is justified by tradition, with a very low level of supporting evidence in the scientific literature.
