Areca catechu is an important ancient drug commonly known as Supari in ayurvedic system of medicine. A lot of research work has been done on Areca catechu regarding various cardiovascular disorders such as Hypertension, Arrhythmia but no work has been done to find out its cardioprotective activity. Experimental procedures done on Wistar Albino rats as Normal control group (NC) received 0.5ml of normal saline throughout the study and served as control. Isoprenaline group (ISO) received 0.5ml of normal saline throughout the experimental phase and received Isoprenaline (85mg/kg, s.c.) on 14th and 15th day at a time lapse of 24 hours. Standard group (STD) received Metoprolol (pure) (10mg/kg/day, p.o.) for 13 days and received Isoprenaline (85mg/kg, s.c.) on 14th and 15th day. Test group received Areca catechu extract (100mg/kg/day, p.o.) and (200 mg/kg/day, p.o.) respectively for 13 days and Isoprenaline (85mg/kg, s.c.) on 14th and 15th day. On 16thday animals were sacrificed. The level of marker enzyme in serum as AST, ALT, CK, LDH, Troponin-I have shown significant decrease (P

Arecacatechu, commonly known as supari, consists of dried ripe nuts that came under Arecaceae family, which is cultivated in the tropical region of India and Southeast Asia. It is a prevalent traditional herbal medicine that is chewed to separate collected fluid in the alimentary canal and for killing worms. Areca catechu seed contains alkaloids (arecoline, arecaine, arecaidine, guvacoline, guvacine, and choline), tannin, gallic acid, gum, and various minerals such as copper, calcium, phosphorus, and iron. The chemical constituents of this plant have been used as antidiabetic, stomatitis, bleeding gums, gingivitis, conjunctivitis, glaucoma, leucorrhoea, urinary disorders, anorexia, diarrhea, blood pressure regulating activity, antiulcerogenic, antioxidant activity, anticonvulsant activity, central nervous system stimulant activity, antifertility, oxytocic activity, antiviral activity, anthelmintic, and foul breath. It showed a dose‐dependent toxicity profile, and various research has been done regarding its safety analysis and it would be considered safe when administered in the prescribed dose. The purpose of the present paper is to make available an up‐to‐date review on the ethnic, traditional description, morphology, phytochemistry, and the pharmacological and toxicological profile of this plant. Furthermore, the possible advances, trends, and a perspective for forthcoming research of this plant have also conversed.

High risks of cardiovascular diseases in women are associated with low estrogen levels. Ischemic preconditioning (IPC) exhibits protection in the heart by Glycogen synthase kinase-3β (GSK-3β) phosphorylation that inhibits the mPTP opening, and this protective action of IPC is attenuated by estrogen deficiency. An experiment was performed on female Wistar rats with/without ovariectomy (OVX). Isolated rat heart was attached with perfusion assembly. Infract size, coronary flow, LDH, CKMB and histopathology were estimated. Sham control group decreased the LDH, CKMB and infract size in normal rat heart. The IPC mediated protection of heart was attenuated in OVX rat heart. Inhibition of GSK-3β is found to enhance the threshold of mPTP opening during reperfusion. The treatment with atractyloside stuck significantly the protection of heart of IPC in normal and OVX rat heart. These observations show that downregulation of GSK-3β through an impaired opening of mPTP during reperfusion and GSK-3β might be potential adjuvant to IPC against cardiac injury in OVX challenged rats.

Herbal medicine is the core nucleus of holistic medicine which is gaining rapid popularity all over the world and gradually incorporating and integrating its position in the mainstream health care systems. Herbal medicines include plant and their parts that contain active ingredients alone or in combination to increase the efficacy, prevention and treatment of the disease. Analogous to conventional medicines herbal medicines are employed for various illness like cold, inflammation, diabetes, malaria, tuberculosis, cancer and so on. Indian traditional medicines or medicinal plants are indispensable source of new drugs. Foeniculum vulgare also known as Fennel, a member of Apiaceae family is used for various health benefits such as, it helps to regulate blood pressure, reduce water retention, improve eyesight and helps in reducing acne, constipation, arthritis, cough, gingival wound etc. Solanum nigrum also known as Makoh, a member of Solanaceae family is used in diverse medical conditions such as used to treat fever and to alleviate pain, used in treating the mouth ulcers, good herbal remedy for asthma, is the main ingredient in various medicines prepared to treat various liver disorders, helps in treating UTI and has excellent hepatoprotective and anti-inflammatory activity. Cichorium intybus also known as Kasni, a member of Asteracece family is used in inflammation, hepatomegaly, digestive ailments, malaria, gout, sedative. It is a remedy for high blood pressure, constipation, liver disorders, gallbladder disorders, skin inflammation, loss of appetite, heart failure and cancer. These drugs provide a noteworthy basis in pharmaceutical biology for the development and formulation of new drugs for future clinical uses.

Acute and subacute toxicity screening of novel entrants in the stream of polyherbal formulations opens new doors towards the scientific approach of establishing them in the clinical market. Toxicity profiling asserts the humongous pharmacological potential that the natural herbs hold and establishes their safety profile. To exemplify this statement, this study further deals with acute and subacute toxicity studies of an olive oil-based polyherbal combination (PHC). This combination has been developed with the view that it proves to be clinically effective in diabetic cardiomyopathy and neuropathy. However, until now, the acute and subacute toxicity studies have been done on the developed PHC, and experimentally effective dose combinations have been identified. The follow-up part of this research includes the screening of the PHC against specific in vivo screening models in its initial stages. This research paper strictly summarises the acute and subacute profile of the salubrious polyherbal combination. Three herbs with strong literature background were selected: Tinospora cordifolia, Withania somnifera and Boerrhavia diffusa; and their crude extracts were prepared. The reported ED50 values of each of these plants were selected and mixed in 5 different combinations and subjected to Acute Toxicity studies. It was followed by the 28-days subacute toxicity screening of 9 different combinations that were elucidated from the acute toxicity study results. The findings were supported with recovery group studies to conform to any late toxicity symptoms of the polyherbal combination. The findings of this study helped in reaching some pathbreaking conclusions on the polyherbal combination designed.

The dissemination of the 2019 novel coronavirus (2019-nCoV) is presenting the planet with a new health emergency response or threat to health. The virus emerged in bats and was disseminated to humans in December 2019 via still unknown intermediate species in Wuhan, China. It is disseminated by inhalation or breaks out with infected droplets and the incubation period is between 2 and 14 days. The symptoms usually include high body temperature, cough, sore throat, dyspnea, low energy or tiredness, and weakness. The condition is moderate in most people; but in the elderly and those with comorbidities, it advances to pneumonia, acute respiratory distress syndrome (ARDS), and multiple organ failure. Popular research work includes normal/low WBC with upraised C-reactive protein (CRP). Treatment is generally supportive and requires home seclusion of suspected persons and rigorous infection control methods at hospitals. The Covid-19 has lower fatality than SARS and MERS. Among the proposed therapeutic regimen, hydroxychloroquine, chloroquine, remdisevir, azithromycin, toclizumab, and cromostat mesylate have shown promising results, and the limited benefit was seen with lopinavir–ritonavir treatment in hospitalized adult patients with severe COVID-19. Early development of the SARS-CoV-2 vaccine started based on the full-length genome analysis of severe acute respiratory syndrome coronavirus. Several subunit vaccines, peptides, nucleic acids, plant-derived, and recombinant vaccines are under pipeline. Research work, development of new medicines and vaccines, and efforts to reduce disease morbidity and mortality must be encouraged to improve our position in the fight against this disease and to protect human life.

Diabetic neuropathy is a chronic complication of diabetes mellitus affecting about 50% of patients. Its symptoms include decreased motility and severe pain in peripheral parts. The pathogenesis involved is an abnormality in blood vessels that supply the peripheral nerves, metabolic disorders such as myo-inositol depletion, and increased nonenzymatic glycation. Moreover, oxidative stress in neurons results in activation of multiple biochemical pathways, which results in the generation of free radicals. Apart from available marketed formulations, extensive research is being carried out on herbal-based natural products to control hyperglycemia and its associated complications. This review is focused to provide a summary on diabetic neuropathy covering its etiology, types, and existing work on herbal-based therapies, which include pure compounds isolated from plant materials, plant extracts, and Ayurvedic preparations.

The aim of this study is to explore the effect of Tinospora cordifolia (Guduchi) on cardiotoxicity in streptozotocin induced diabetic rats. All animals were divided into 8 groups of 5 animals each, fed with High fat diet (HFD) except the ones in Sham, NPD and NPD-C-I groups. Food and water intake were monitored daily at the same time during the experimental period. The Food Efficiency Ratio (FER) was calculated during the experiment period. All the animals were pretreated as per the treatment protocol. Streptozotocin; STZ (50mg/ Kg) was administered subcutaneously to induce the diabetes which was confirmed in all the administered groups by testing blood glucose level after 48 hours. Cardiotoxicity was induced by administering isoprenaline (85mg/Kg). Troponin was checked after 4-5 hours of second isoprenaline injection to confirm cardiac damage. At the end of the study the animals were weighed and then sacrificed with high dose of Diethyl ether. Blood samples were collected from retro-orbital plexus and were used for biochemical estimations. The hearts were excised immediately and were weighed. Photomicrographs were taken for gross examination rest of the hearts were kept in 10% Formalin solution for histopathological studies. Pretreatment with Tinospora cordifolia (200 mg/kg ) showed very significant improvement against Streptozotocin induced diabetes (p< 0.01) as blood glucose level were found to be decreased when compared to the untreated D-HFD group. The Food efficiency ratio (FER) was found to be significantly increased when compared to D-HFD (p

Diabetes mellitus is a worldwide epidemic disease that eventually advances to a chronic stage and affects different vital organs by intensifying the underlying pathological factors, and through the remodeling of the tissues by the generation of reactive oxygen species leading to the development of respective organ failure. Two such complications are painful neuropathy and cardiomyopathy; both of which are common and progressive complications of diabetes. The symptoms of peripheral neuropathy include tingling, burning, lancinating pain, hyperesthesia, and allodynia. The course of the disease progression may vary from intermittent, mild symptoms to severe chronic, and daily pain; which culminates into poor quality of life. Another complication of diabetes mellitus, diabetic cardiomyopathy, is defined as a ventricular dysfunction disorder that occurs in diabetic patients. The development of the disease is characterized by a hidden subclinical period, during which cellular, structural changes and abnormalities lead to diastolic dysfunction, followed by systolic dysfunction, and terminating into heart failure. Left ventricular hypertrophy, metabolic abnormalities, extracellular matrix changes, small vessel disease, cardiac autonomic neuropathy, insulin resistance, oxidative stress, and apoptosis are the most important pathological advancements that lead to diabetic cardiomyopathy. Various pharmaceutical agents from different pharmacological categories have been proposed for the symptomatic treatment of painful diabetic neuropathy; however, it is a herculean task to select a drug due to the wide range of choices and lack of consistent guidelines for treatment. Similarly, treatment of cardiomyopathy is based on the general therapeutic rules of management of heart failure and no specifications have yet been addressed for this condition. Therefore, more studies are required to improve our knowledge of these complex syndromes. From this perspective, this review is designed to delineate a general overview of neuropathy and cardiomyopathy, referring to the conventional therapies in use and possible unconventional, natural, herbal, and safe treatments for both the above-mentioned complications of diabetes.
