For OVER-active adrenals: Ashwagandha can be great. It is best known for lowering cortisol, which tends to be higher in those with over-active adrenals.
For UNDER-active adrenals: Most other herbs are great for under-active adrenals since they tend to balance cortisol instead of lowering it (even though most studies are focused on just lowering cortisol, these herbs are known to be more balancing). So Holy Basil, Rhodiola, Reishi Mushroom, and Schisandra berry are usually good. I like this blend from Herb Pharm that has these herbs.
Glandulars: These also depend on the person’s adrenal status.
