Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Nettle (Urtica dioica), commonly used as a herbal remedy, has a long history of traditional use for supporting overall vitality, which is often extended to supporting the adrenal glands. Traditional herbalists have used nettle as a general tonic, particularly for its high nutrient content, including vitamins (such as vitamin C and B vitamins) and minerals (such as magnesium and iron), which are considered beneficial for individuals under stress or fatigue—conditions associated with adrenal function. However, direct historical references to nettle specifically supporting the "adrenal glands" are limited; rather, its use is more broadly connected to “restorative” or “adaptogenic” effects in folk medicine.

Scientific studies on nettle’s effects focus mostly on its anti-inflammatory, diuretic, and antihistamine properties, not directly on adrenal health. There is a lack of clinical trials or mechanistic studies specifically linking nettle extract to adrenal gland support or hormone production (such as cortisol). Therefore, while nettle is traditionally included in herbal blends for “adrenal support,” this usage is not strongly validated by modern science. The traditional evidence is moderate (hence a rating of 2), mostly based on its role as a nutritive tonic rather than a direct effect on the adrenal glands.
