Description_x000D_ General description_x000D_ Natural product derived from plant source._x000D_ Biochem/physiol Actions_x000D_ Dehydroabietic acid (DHA), along with abietic acid (AA), are resin acids used in the production of wood pulp and common in paper mill effluents. Dehydroabietic and abietic acids are potentially toxic and inhibit growth, studies have shown that the levels of DHA and AA in pulp and paper mill effluent, as well as paperboard products used in food packaging, are well below effective levels. DHA has potential as treatment for obesity and metabolic syndrome, obese diabetic KK-Ay mice treated with DHA showed decreased plasma glucose, insulin, and triglyceride levels.
