chinese terms weak adrenals are known as "Yin Deficiency". I suggest you research on some chinese herbs such as Dong Quai,Cordyceps sinensi, Reishi Mushroom and Bupleurum.
The megafood for adrenal support are Reisha mushroom(used as a sedative for dizziness and insomnia), and cordyceps sinesis followed by bupleurum which is a "deep liver cleanser" and dong quai which is targeted for female hormones.
Reishi mushroom also provides excellenet benefit against candida. It helps to reduce or eliminate fungal overgrowth and has a dramatic effect in clearing food allergies
