The purpose of this study was to collect data for future clinical investigations and research on the safe and efficient use of various herbal medicines to treat hyperglycemia. One of the primary contributing reasons to the onset and progression of diabetic nephropathy is hyperglycemia, and many modern treatments are made from plants since they frequently have fewer side effects than the conventional medications that are now available. The medicinal plants include Sesbania sesban, Elaeis guineensis, Tecoma stans, Aloe barbadensis miller, Zingiber officinale Roscoe, Olea europaea, Anogeissus acuminata, Juglans regia L., Fragaria ananassa, Ginkgo biloba, Laurus nobilis L., Dryopteris dilatata, Moringa oleifera, Punica granatum L., Lycium chinense, Rumex nervous alkaloids and flavonoids are the primary phytoconstituents that aid in the therapy or cure of diabetic nephropathy. The therapeutic effects of medicinal plant leaf extract may be due to the wide range of bioactive compounds present, including various phytoconstituents such as alkaloids and flavonoids, glycosides, steroids, terpenoids, and phenolics. Alkaloids and flavonoids are the primary phytoconstituents that aid in the therapy or cure of diabetic nephropathy.
