Elephant's Head (Pedicularis groenlandica) has a history of traditional use in Native American herbal medicine, but its documented applications are limited and not widely recognized in mainstream herbal texts. There are some reports that various Pedicularis species, including Elephant's Head, were used for their mild sedative and muscle relaxant properties. However, there is very little recorded use specifically targeting the mucus membranes or for respiratory health in general. Most ethnobotanical sources do not emphasize Elephant's Head as a primary herb for conditions involving the mucus membranes, such as those affecting the respiratory or digestive tracts.

There is no substantial scientific research investigating the effects of Elephant's Head on mucus membranes or related body systems. The plant has not been the subject of significant pharmacological studies, and any claims regarding its benefits for the mucus membranes are not supported by clinical trials or rigorous scientific data. The rating of 1 reflects the existence of some traditional use of Pedicularis species, but not specifically or robustly for mucus membrane support. In summary, the use of Elephant's Head for this body system is based primarily on limited traditional knowledge rather than scientific validation.
