Self-heal herb improves symptoms of diabetic nephropathy
08/16/2019 // Melissa Smith // Views

A team of researchers from Wonkwang University in South Korea looked at the effect of the self-heal herb (Prunella vulgaris) on improving the symptoms of diabetic nephropathy, also known as diabetic kidney disease. The research team published their findings in The American Journal of Chinese Medicine.

  • Diabetic nephropathy is the most common complication and the leading cause of death associated with diabetes.
  • The self-heal herb is a popular traditional medicinal plant used to treat abscess, scrofula, hypertension, and urinary diseases.
  • For this study, the research team used an aqueous extract of the self-heal herb to tests whether it can inhibit kidney inflammation and fibrosis in cell and animal models.
  • The pretreatment with self-heal herb suppressed inflammatory cytokines and significantly decreased fibrosis markers connective tissue growth factor (CTGF) and collagen IV.
  • It also suppressed inflammatory factors such as intracellular cell adhesion molecule-1 (ICAM-1) and monocyte chemoattractant protein-1 (MCP-1).
  • Additionally, it inhibited the activation and translocation of nuclear factor kappa-B (NF-?B) and significantly improved reactive oxygen species in a dose-dependent manner.
  • In diabetic rat models, treatment with the self-heal aqueous extract significantly reduced blood sugar, blood urea nitrogen, and plasma creatinine levels.
  • It also inhibited fibrosis-related proteins such as collagen IV and TGF-Beta1.
  • These results indicated that aqueous self-heal herb extract exhibits a potent protective effect against diabetic nephropathy symptoms such as inflammation and fibrosis.

Taken together, the research team concluded that self-heal herb may be used as a potential treatment for kidney diseases, such as diabetic nephropathy.
