What is Insulin?

  Insulin is a peptide hormone, produced by beta cells of the pancreas to regulating carbohydrate and fat metabolism in the body. Insulin causes cells in the liver, skeletal muscles, and fat tissue to absorb glucose from the blood. In the liver and skeletal muscles, glucose is stored as glycogen, and in fat cells (adipocytes) stored as triglycerides .Insulin stops the use of fat as an energy source by inhibiting the release of glucagon .

  With the exception of the metabolic disorder diabetes mellitus and metabolic syndrome, insulin is provided within the body in a constant proportion to remove excess glucose from the blood, which otherwise would be toxic. When blood glucose levels fall below a certain level, the body begins to use stored sugar as an energy source through glycogenolysis, which breaks down the glycogen stored in the liver and muscles into glucose, which can then be utilized as an energy source. As a central metabolic control mechanism, its status is also used as a control signal to other body systems (such as amino acid uptake by body cells). It has several other anabolic effects throughout the body.

  When control of insulin levels fails, diabetes mellitus can result. As a consequence, insulin is used medically to treat some forms of diabetes mellitus. Patients with type 1 diabetes depend on external insulin ( commonly injected subcutaneously) for their survival because the hormone is no longer produced internally. Patients with type 2 diabetes are often insulin resistant and, because of such resistance, may suffer from a "relative" insulin deficiency. Some patients with type 2 diabetes may eventually require insulin if other medications fail to control blood glucose levels adequately. Over 40% of those with Type 2 diabetes require insulin as part of their diabetes management plan. The human insulin protein is composed of 51 amino acids.

  In 1923 J. B Collip and C.H. Best received Nobel Prize for Medicine for co-discovery of insulin with Banting and MacLeod. Pancreatic insulin was discovered in 1921-1922 and insulin was established as the universal drug for the treatment of diabetes. Right after the discovery of insulin, J. B. Collip and C. H. Best reported the presence of insulin-like substances in plant materials like green tops of onions, lettuce leaves, green bean leaves, barley roots, etc. 


 According to International Journal of Ayurveda Research a new study on Insulin plant (Costus igneus) was published recently. The leaves of insulin plant (Costus igneus) reduced the fasting and postprandial blood sugar levels, bringing them down towards normal, in dexamethasone-induced hyperglycemia in rats. Reduction in the fasting and the postprandial blood sugar levels with leaves of insulin plant was comparable with that obtained with Glibenclamide 500 g/kg at 250 mg/kg/day and 500 mg/kg/day of powdered leaves of the insulin plant (Costus igneus).
