Natural honey as potential diuretic, [experimental study]

ABSTRACT

In this study the potential diuretic effect of honey was investigated in anaesthatized dogs and compared to hydrochlorothiazide as a standard diuretic drug. Intravenous administration of honey 1 gm/k gm in a 40% dilution in normal saline produced significant augmentation of volume of urine output, urine sodium, chloride and to less extent potassium excretion. The increase in cation excretion is covered with commonsurate increase of chloride ion i.e. chloride ions appears to be the main attending anion. The diuretic effect of honey starts immediately after administration and reaches maximum after 20 to 40 minutes. The pattern of diuretic effect of honey as well as the magnitude of this effect, compare favourably with the response to hydrochlorothiazide [2.5 mg/kgm I.V]. However, honey has the advantage that it produces less kaliuresis. Measurement of serum concentration of sodium, chloride and potassium following administration of honey or hydrochlorothiazide revealed that concentrations of these ions are not altered except the potassium concentration which shows mild hypokalaemia in dogs treated with hydrochlorothiazide. A mixture of glucose-fructose - sucrose - maltose [GFSM] in the same proportions as they are found in honey was tested in a group of dogs in a dose of 1 gm/kgm i.e. equal to the o dose of natural honey, this mixture failed to produce any diuretic effect. Such finding could suggest that the diuretic effect of honey is not attributed to its sugar content. Although the various mechanisms of action or the site of the diuretic effect at the nephron have not been elucidated, this is the first study which provides a controlled scientific evidence for the potential diuretic effect of honey. These preliminary results suggest that honey may be used clinically as a safe diuretic. However, further investigations are required to explore the mechanism [s] of this property and fully to ascertain it's clinical potential
