"DAK", a traditional decoction in Palau, as adjuvant for patients with insufficient control of diabetes mellitus type II.

Ethnopharmacological Relevance: Can a medicinal plant be useful when standard modern treatment is insufficient? After a population survey in the Republic of Palau (retrospective treatment-outcome study, following the reverse pharmacology approach) on local treatments and associated outcomes for diabetes, a traditional drink made with Phaleria nisidai Kaneh and several other plants called "Delal A Kar", (meaning "mother of medicine") appeared as a promising therapy. This is the first clinical study on a standardized version of "Delal A Kar" called DAK.

Aims/hypothesis: This is a study of the effect of DAK as adjuvant therapy when diabetes control is insufficient.
