Rating (out of 5): 2

Blue Vervain (Verbena hastata) has a long history of use in traditional Western herbalism, where it has been employed as a nervine and mild sedative to support the nervous system, particularly in cases of stress, anxiety, and tension. Its reputation for supporting the adrenal glands stems primarily from this traditional use: herbalists have reasoned that by calming the nervous system and reducing stress, Blue Vervain may indirectly benefit the adrenal glands, which are responsible for the body's stress response via hormone production (such as cortisol). However, there is a lack of direct historical documentation explicitly connecting Blue Vervain to adrenal gland health; its association is more a result of its use for nervous exhaustion and stress-related ailments.

From a scientific perspective, there is very limited evidence to support the use of Blue Vervain specifically for adrenal gland support. Some preliminary studies suggest that extracts of Blue Vervain may have mild anti-inflammatory and anxiolytic effects, but these findings are not directly linked to adrenal function, and robust clinical trials are lacking. Therefore, while tradition supports its use for stress and nervous tension (with an indirect connection to the adrenals), scientific validation for direct adrenal support is minimal.
