A follow-up study carried out in T2DM patients showed that, in diet-controlled subjects (FBG 117 ± 16 mg/dL; fasting plasma insulin 29 ± 8 μU/mL; n = 6), ingestion of G. biloba produced no significant effect on the insulin before and after ingesting G. biloba, respectively [1068]. Here, INS is linked to type 2 diabetes mellitus.
