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

Kola nut (Cola acuminata and Cola nitida) has a long history of traditional use in West African cultures, primarily as a stimulant and for its perceived energizing effects. The kola nut contains caffeine and theobromine, both of which are central nervous system stimulants. In traditional herbalism, particularly in some systems of Western herbalism, kola nut is sometimes suggested as a tonic for the "adrenal glands" or to support energy levels and combat fatigue—conditions often associated with adrenal insufficiency or so-called "adrenal fatigue" (a non-medical term).

However, scientific evidence directly supporting kola nut as an "adrenal gland support" is limited. Most of the physiological effects of kola nut can be attributed to its caffeine content, which stimulates the central nervous system and may temporarily increase alertness and reduce the perception of fatigue. There is no robust clinical data demonstrating that kola nut has a specific effect on adrenal gland function or that it can treat adrenal insufficiency. Thus, its use for this purpose is based more on traditional herbal practice and the general stimulating effect, rather than scientific validation specifically for adrenal health.

In summary, the use of kola nut for adrenal support is primarily traditional, with a low to moderate evidence rating, as it relies on its general stimulant properties rather than direct effects on the adrenal glands.
