Azorella compacta is traditionally used in the form of tea (infusion). Eight polyphenols (chlorogenic acid, 6,8-di-C-hexosyl apigenin, isoorientin, orientin, dicaffeoylquinic acid, biochanin A-O-glucoside, biochanin A-O-(malonyl)glucoside, and licoisoflavone A) were identified in lyophilized infusion of A. compacta (ACI).
The human natural killer (NK) cells were substantially activated by ACI, whereas T cells and granulocytes were slightly stimulated.
