Improved metabolic control and hepatic oxidative biomarkers with the periconception use of Helichrysum plicatum ssp....

Our aim was to investigate the hypoglycaemic and antioxidant effects of the Helichrysum plicatum ssp. plicatum (HPsP) plant extract in the streptozotocin-induced type 1 diabetes rat model during pregnancy. Five groups (n = 8, each) were formed: (1) diabetic non-mated control, (2) non-diabetic mated control, (3) diabetic mated control, (4) diabetic non-mated treatment and (5) diabetic mated treatment. The HPsP extract was administered orally for 15 days (250 mg/kg body weight), beginning 3 days before mating. The extract led to decreased blood glucose, increased serum insulin, and decreased serum triglycerides in pregnant and non-pregnant diabetic animals. Liver thiobarbituric acid reactive substances (TBARS) and reduced glutathione (GSH) measurements in extract-treated diabetics were similar to non-diabetic pregnant controls, indicating probable reversal of increased lipid peroxidation in the liver. The mean pup number tended to increase (p = 0.06) with extract administration. In conclusion, the beneficial effects we encountered with the periconception use of the studied herbal extract warrant further investigation.
