Fraxinus excelsior shows hypoglycemic effect in patients with postprandial hypoglycemia, which was a common popular belief until the study cited here presented clinical evidence to support the claim. On the other hand, it was observed to also induce insulin secretion after glucose injection. [1]


Another study suggests that Fraxinus excelsior supports glucose homeostasis thus helping regulate the balance of insulin and glucagon as study considers elderly overweight patients. [2]

It was also observed how the presence of polyphenols, tannins, coumarins and flavonoids endow it with antibacterial and antioxidative properties which could be beneficial in treating conditions related. [3]

According to 2 sepparate studies, Fraxinus excelsior also showed antiobesity and hypoglicemic effect on obese animals (mice/rats), associated with weight loss in one case [5], and controlled/ limited weigh gain in the other. [4] The animal subjects of these studies suffered from metabolic disorders. This suggests that Fraxinus e. benefits could be successfully applicable in human patients too. [4, 5]
