Results of numerous scientific investigations revealed that phytochemicals present in medicinal plants (Allium sativum, Momordica charantia, Hibiscus sabdariffa L., and Zingiber officinale) possess anti-hypoglycemic activities and show promise for the prevention and/or control of DM.
Results also revealed that intake of vitamins C, D, E, or their combination improves the health of diabetes patients by reducing blood glucose, inflammation, lipid peroxidation, and blood pressure levels.
However, very limited studies have addressed the health benefits of medicinal plants and vitamins as chemo-therapeutic/preventive agents for the management of DM.

Also, daily use of the bitter melon leaf extract in oral form for 28 days significantly increased the total ulcer healing score (2 RCTs; WMD = 0.40; p = 0.001).
Additionally, based on qualitative synthesis, the adjuvant use of herbal agents seems an intriguing choice to manage DFU.
Nonetheless, considering the undesirable methodological quality of most studies and the high heterogeneity in administered herbal formulations, more robust trials are required to build a solid conclusion regarding the use of herbal products for healing DFU.
