Concentrated broccoli sprout extract (BSE) was investigated in a randomized double-blind placebo-controlled study for its effect on fasting blood glucose levels and glycated hemoglobin (HbA1c) in 103 type 2 diabetic patients. Following 12 weeks of BSE, fasting blood glucose and HbA1c were reduced, particularly in patients with obesity and dysregulated type 2 diabetes.

A recent study compared nanocrystalline silver, manuka homey, and conventional dressing for the treatment of diabetic foot ulcer. The results showed that the proportions of complete ulcer healing were 81.8%, 50%, and 40% in the silver, honey, and conventional groups, respectively. The ulcer size reduction rate was higher in the silver group (97.45%) than the honey group (86.21%) and the conventional group (75.17%). In bacteriology, silver showed a greater rate of microorganism reduction although it was not significant.
Type 2 diabetics consumed chamomile tea (3 g/150 mL hot water) 3 times per day immediately after meals for 8 weeks. Chamomile tea significantly decreased concentration of glycosylated hemoglobin, serum insulin levels, homeostatic model assessment for insulin resistance, and serum malondialdehyde, compared with control group. Total antioxidant capacity, superoxide dismutase, glutathione peroxidase, and catalase activities were significantly increased by 6.81%, 26.16 %, 36.71 % and 45.06% respectively in chamomile group compared with the control group.
Although honey has been used for the treatment of wounds since ancient time, a review of the research looked specifically at topical honey for diabetic foot ulcer. The review showed that honey is safe for diabetic foot ulcer patients but more research is needed to confirm its efficacy.
