Diabetic foot ulcer healing potential of Tagetes erecta L. flower extract on successive administration in alloxan-induced diabetic rats via modulation of liver functions

Diabetes mellitus is a prevalent endocrine disorder characterized by inadequate insulin production by the pancreas or improper utilization of insulin by the body, which imposes severe health complications, including cardiovascular, kidney, and neurological disorders with a high potential of foot ulcers. Globally, diabetes is responsible for over 70 % of limb amputations. Alloxan was used to induce diabetes in rats while foot ulcers were induced by the excision method in diabetic rats. Diabetes was confirmed by measuring the parameters like blood glucose, body weight changes, urine excretion, and other biomarker levels after oral administration of Tagetes erecta L. flower extract (TEFE) at different doses. During the work, it was observed that TEFE demonstrated a dose-dependent effect on blood sugar level from 370.2 mg/dl to 113.00 mg/dl and healing of diabetic foot ulcers in a 13 days animal model (p < 0.01). There is significant decline in SGOT, SPGT and ALP levels when compared with diseased group animals. Decrease in wound size was observed when TEFE was administered to diabetic foot ulcer rats. These exciting results steered to enumerate the possible role of TEFE in Diabetes mellitus through a panel of mechanisms of action like inhibition of free radical generation, modulation of liver enzymes and metabolism of glucose etc. The above findings support the hypoglycaemic and diabetic foot ulcer healing potential of TEFE. Moreover, further investigation is required to completely understand the possible mechanism of TEFE.
