Elephant's Head (Pedicularis groenlandica), also known as "Elephant Head Betony," has a history of use in traditional herbal medicine among some Native American tribes and herbalist practices. The plant has primarily been used as a nervine, muscle relaxant, and for its supposed soothing effects on the nervous system and muscles. There are anecdotal reports and ethnobotanical records of its use for promoting relaxation, easing muscle tension, and sometimes for addressing urinary discomfort or as a mild diuretic, which indirectly links it to kidney support through promoting urination. However, there is no direct or robust scientific evidence to validate any specific kidney-protective or kidney-supportive effects of Elephant's Head.

The traditional use of Elephant's Head for kidney support appears to be based on its general relaxing and diuretic qualities, rather than on any specific or direct action on kidney function. There are no significant clinical trials, phytochemical studies, or pharmacological investigations that demonstrate or clarify its efficacy or mechanisms for supporting kidney health. Therefore, while it is justified to say that Elephant's Head has a traditional association with kidney support, the evidence is limited, not strongly documented, and lacks scientific validation.
