This review is on Indian herbal medications and plants, particularly those utilized in India, for the treatment of diabetes. Diabetes is a significant illness that affects people worldwide and from all walks of life. It is turning out to be a serious health issue in India, particularly in the cities. Herbal formulations are recommended because they have fewer side effects and are less expensive than other techniques to lessen the negative effects of diabetes and its secondary complications. A list of herbal medications used to treat diabetes as well as medicinal plants with demonstrated anti-diabetic properties and associated health benefits is compiled. Among them are Momordica charantia Ocimum, Eugenia jambolana, and Allium sativum, Phyllanthus amarus, Withania somnifera, Tinospora cordifolia, Pterocarpus marsupium, Ocimum sanctum, and Trigonella foenum graecum. Free radical damage is one of the etiologic factors linked to the development of diabetes and its consequences, so an antidiabetic molecule with antioxidant characteristics would be more advantageous. Consequently, details regarding these medicinal plants' antioxidant benefits are also provided


Introduction
Diabetes mellitus, a non-infectious endocrine disorder, is typified by a disruption in the metabolism of carbohydrates and is linked to hypoglycemia [1] [2].It is associated with the development of a number of serious illnesses, including macro-vascular (peripheral vascular disease and coronary heart diseases) and micro-vascular (nephropathy, retinopathy, and nephropathy) [3].Diabetes mellitus, commonly referred to as "sweet urine" and muscle atrophy, has been linked to the illness.Insulin is a hormone released from the pancreas that keeps blood glucose levels stable.The pancreas produces insulin to maintain the level of glucose when these levels rise.Hyperglycemia is a result of reduced or absent insulin production in diabetic patients [4].There are three types of diabetes mellitus.type 1, Gestational diabetes mellitus and type 2. Insulin-dependent diabetes mellitus, also referred to as type 1 diabetes mellitus, is caused by the complete failure of the β cell in the pancreatic islets of Langerhans.Insulin non-dependent diabetes mellitus, or type 2 diabetes mellitus, is characterized by a transient loss of β cell mass caused by a genetic predisposition.It primarily affects obese individuals and is linked to elevated blood pressure and cholesterol levels.Reducing insulin resistance and boosting insulin secretion are the goals of type 2 diabetes treatment.Hyperglycemia is a symptom of gestational diabetes, which affects pregnant women.Typically, it manifests in 2-4% of second-or third-trimester pregnancies [5].Diabetes mellitus symptoms include blurred vision, slow wound healing, polydipsea, polyuria, polyphagia, fatigue, nausea, and vomiting.In men, impotence is also a symptom of the disease [6].

Diagnosis of diabetes mellitus
Blood sugar levels can be analyzed to determine the level of diabetes.In a healthy man, blood sugar levels can reach up to 160 mg/dl after a meal and 80 mg/dl during a fast.Various tests, such as the finger prick blood sugar test, fasting blood sugar test, glucose tolerance diagnostic test, and glycohemoglobin, are used to diagnose diabetes in laboratories [6].

Pathophysiology of diabetes mellitus
Oxidative stress plays a significant role in diabetes pathophysiology.Oxidative stress refers to the disparity between the generation of reactive oxygen species (ROS) and the ability of enzymatic or nonenzymatic antioxidants to counteract them.Hydroperoxyl, super oxide, peroxyl, and hydroperoxyl are examples of free radicals found in reactive oxygen species.Non-radical species like hydrogen peroxide are also included.Superoxide dismutase, glutathione reductase, trace elements, vitamins A, C, and E, and carotenoids are all found in antioxidants.Oxidation occurs in low density lipoprotein cholesterol the existence of reactive oxygen species, which cause foam cells and plaques associated with arterial sclerosis to form by binding to the hunter receptor in scavenger cells.These ROS have the ability to stimulate a number of harmful pathways, which are crucial in the development of diabetes mellitus.The electron transport chain, the glucosamine pathway, the sorbitol aldose reductase pathway, and the stimulation of protein kinase C are a few significant pathways.Induction of these pathways and their mode of action can result in the development of amylin, lipid peroxidation, atherosclerosis, programmed cell death, and failure of the function of the pancreatic β cell.It has been demonstrated that the negative regulator for these sequence-specific DNA binding factors, kelch like ECH associated protein 1, and nuclear factor erythroid derived 2 like 2, have a significant protective mechanism for cells against oxidative stress [7].

Anti-diabetic drugs
Diabetes mellitus can be avoided by controlling blood sugar levels with a variety of medications, getting to alternate yoga poses, workout regimens, or dietary plans [8].Insulin treatment for type 1 diabetes and other oral hypoglycemic medications such sulphonylureas, thiazolidinediones, and peptide analogs for type 2 diabetes are currently the available therapies for diabetes mellitus [4] [9].

Herbal Remedy:
The biggest question facing medical professionals today is how to treat diabetes mellitus without causing any negative side effects.Approximately 800 medicinal plants are used to prevent diabetes mellitus, according to the World Ethanobotanical Society.Only 450 medicinal plants have been shown in studies to have anti-diabetic qualities, of which 109 have a full mode of action.Traditional medicinal plants with their active ingredients and therapeutic qualities were used in the past by both medical professionals and laypeople to treat a variety of illnesses, including diabetes, cancer, and heart disease.
In India and China, traditional herbal remedies for diabetes have a long history of use.Numerous books, including Susruta Samhita and Charaka Samhita, are available and explain the phy-topharmacology features of diabetes and its negative effects.[10]Synthetic medications used to treat diabetes have been linked to a number of negative side effects, including nausea, vomiting, dysentery, headaches, alcohol flush, swelling, malignant anemia, and dizziness.Because they have fewer negative effects and side effects than synthetic drugs, herbal medications have been shown to be a better option.Herbal remedies are easily obtained over-the-counter without a prescription.These herbal medications are used to treat serious illnesses.These medications are also used when chemical medications fail to effectively treat a disease.Drugs from the herbal world treat a person's illness and cure them permanently, unlike those from the synthetic world, which do not.Natural herbs, fruit and vegetable extracts, and herbal formulations are used to treat a variety of illnesses without causing side effects.However, chemical drugs are also manufactured artificially and can have adverse effects.When considering allopathic medicines, herbal formulations are more affordable.Environmentally friendly are herbal formulations.A natural product is used to make herbal formulations, whereas chemically and chemically modified natural products are used to make allopathic medicines.Allopathic medicines must be prescribed, but herbal formulations can be purchased without one [11,12]

Traditional herbal Anti diabetic drugs
The anti-diabetic properties of medicinal plants and herbs are currently being utilized in ex-tract forms.
Medicinal plant extracts have been shown in numerous clinical investigations to exhibit anti-diabetic activity and to restore the function of pancreatic βcells [13].

Therapeutic role of crude drugs in DM:
3.1 Allium sativum(Garlic) Roles: Garlic ethanol extract (10 ml/kg/day) frequently demonstrates hypoglycemic action [2].Garlic extract proved to be more effective than glibenclamide, an anti-diabetic medication [15].Rats given STZ were shown to exhibit anti-diabetic effects from ethanol, ethyl acetate, and petroleum ether extract.Several medicinal properties of garlic include anti-platelet, antibacterial, blood pressure-lowering, and cholesterol-lowering effects [16].Due to enhanced hepatic glucose metabolism or increased insulin usage, garlic and its derivatives have hypoglycemic activity, which further reduces the risk of diabetes complications.

Roles : In alloxan-induced diabetic rats, oral administration of an aqueous extract did not alter blood glucose levels, despite the leaves extract (250 mg/kg) demonstrating anti-diabetic activity.Twenty [20] Mangos have a high sugar content, which means that most of their calories could potentially increase blood sugar levels, which is especially dangerous for diabetics.Roles: It is applied to diabetes treatment.It contains lectin, which functions similarly to insulin.A nonprotein connected to insulin receptors is called lectin.By affecting peripheral tissues, this lectin lowers blood sugar levels [21].M. charantia fruit extract (200 mg/kg) exhibits hypoglycemic action.Several compounds found in bitter melon appear to function similarly to insulin and lower blood sugar.According to some research, they may achieve this by increasing the amount of glucose that enters the cells, which subsequently aids in its digestion and storage by the body in the muscles, fat, and liver.Roles: Indian ayurvedic medicines use it to treat a variety of illnesses.Numerous investigations on animals demonstrated that an aqueous extract of Ocimum sanctum leaves (200 mg/kg) exhibited hypoglycemic effects in rats induced by streptozotocin.Additionally, it is used to treat fungal and viral infections, lower stress, treat tumors, and treat gastric ulcers [22,23].Variations in blood sugar levels are indicative of it.Because of its potent anti-inflammatory qualities, tulsi is useful in the treatment of diabetes-related conditions like obesity.Numerous studies suggest that tulsi consumption may enhance insulin secretion and pancreatic beta-cell function.Roles: It is referred to locally as "onion" or "pyaz" and is a member of the Alliumcepa family, Liliaceae.The ether soluble and ether insoluble portions of dried onion powder demonstrated antihyperglycemic action.Its chemical component, allyl propyl disulphide, or APDS, inhibits the liver's ability to break down insulin and stimulates the pancreas to produce more insulin, which raises the concentration of insulin and lowers blood glucose levels.In diabetic rats induced with alloxan, essential oil (100 mg/kg) extracted from red onions frequently exhibits antioxidant, antihyperglycemic, and antitistatin effects.The most effective percentage for treating hyperglycemia and hyperlipidemia is 300 mg/kg Onions are used in the treatment of cancer, diabetes, asthma, and a variety of viral diseases, according to data from numerous clinical trials and animal studies.The Problems With Herbal Remedies in India onions, which support healthy living and immunity while also assisting in blood glucose regulation.

The Prospects of Herbal Treatments for Type 2 Diabetes
People use a wide variety of herbal medications, and new native drugs are frequently added to modern therapeutics.In developing nations, particularly in rural areas, about 80% of the population relies on conventional medical treatments for their medical needs.A significant amount of the preference for natural products has led to a resurgence of interest in herbal drugs in developed countries.As a result, it's important to distinguish between herbal medications prescribed by a doctor and those that are widely available for people to take at home.Diabetes mellitus is becoming more and more common, which poses a serious threat to human health everywhere.Newly, potent medications have been derived from plants and have been shown to have greater anti-diabetic effects than oral hypoglycemic medications in clinical trials.The discovery of plants with potential human benefits as antidiabetic agents has garnered attention in recent years.Additionally, it might offer proof of the advancement of a novel oral medication for the management of diabetes mellitus.Roles: stimulate insulin secretion in diabetic strong antioxidant and anti-inflammatory properties that can aid in the treatment or prevention of a wide range of illnesses, from obesity and high blood pressure to diabetes and high cholesterol.

CONCLUSION:
One of the most prevalent endocrine disorders, diabetes mellitus affects millions of people globally.It is a class of metabolic diseases defined by elevated blood sugar levels brought on by deficiencies in either insulin production, insulin action, or both.Research is shifting toward traditionally available medications with low side effects and a wide range of bioactivity that do not relapse due to the rise in resistance and populations of patients at risk, as well as the limited number of commercially available drugs for diabetes that are still available but have numerous side effects and problems like unwanted hypoglycemic effect.The information in this review article may help researchers, scientists, and health professionals create evidence-based herbal remedies to treat various forms of diabetes.A significant part of developing medications and treating the hyperglycemic issue in diabetes mellitus is played by substances and extracts extracted from various natural resources.
