Elephant's Head (Pedicularis groenlandica) has a history of use in some traditional medicine systems, particularly among Native American groups, for various ailments. However, its use for treating nausea and vomiting is not well-documented or widespread compared to some other herbal remedies. The primary references to Elephant's Head in ethnobotanical literature generally describe its use as a muscle relaxant, mild sedative, or for treating pain and tension. There are occasional mentions of its use as a remedy for digestive complaints, but these are rare and often lack detailed context or specificity regarding nausea and vomiting.

There is virtually no scientific research or clinical evidence supporting the efficacy of Elephant's Head for nausea or vomiting. No pharmacological studies, randomized controlled trials, or systematic reviews have evaluated its effects on these symptoms. The rating of 1 reflects the presence of minimal, mostly anecdotal traditional use, but not enough to represent a robust or widely accepted practice, and no scientific validation exists to support its use for this purpose.
