COVID-19 is the infectious pandemic disease caused by the novel coronavirus. The COVID-19 is spread globally in a short span of time. The Ministry of AYUSH, India which promotes Siddha and other Indian system of medicine recommends the use of formulation like Nilavembu Kudineer and Kaba Sura Kudineer Chooranam (KSKC). The present work seeks to provide the evidence for the action of 74 different constituents of the KSKC formulation acting on two critical targets. That is main protease and SARS-CoV-2 RNAdependent RNA polymerase target through molecular docking studies. The molecular docking was done by using AutoDock Tools 1.5.6 of the 74 compounds, about 50 compounds yielded docking results against COVID-19 main protease while 42 compounds yielded against SARSCoV- 2 RNA-dependent RNA polymerase. This research has concluded that the KSKC has the lead molecules that inhibits COVID-19’s target of main protease of COVID-19 and SARS-CoV-2 RNA-dependent RNA polymerase.

The review was carried out to discuss in detail about the polymeric nanoparticles for diabetic treatment. The diabetes is the chronic metabolic disorder characterized by the deficiency of insulin production. The various treatments are available for the diabetes and the nanoparticles are having the several advantages. The various types of nanoparticles are available for the anti-diabetic drugs; the polymeric nanoparticles are the one of the most commonly used nanoparticles. The polymeric nanoparticles are commonly 10-1000nm in size. The polymeric nanoparticles are formulated by drug with the polymers. The main advantages of the polymeric nanoparticles are the simplest preparation method, targeted delivery, the minimizing of the dose and high therapeutic efficiency. In this review was mainly can be focused on advantages, disadvantages of polymeric nanoparticles, various polymers, various formulation techniques, diabetes disease profile, insulin production, various anti-diabetic drugs and the polymeric nanoparticle formulation of anti-diabetic drugs.

World wide liver toxicity is the most prevelent healthcare problem. We need to address this with herbal based medicine because herbal products have high efficacy and less side effects. Many of the Ehretia genus (Boraginaceae) have the hepatoprotective property. But Ehretia microphylla (EM) was not reported yet for its hepaptoprotective potential. Therefore the current research was aimed to evaluate the hepatoprotective action of EM. The hepatoprotective activity of EM was assessed against the paracetamol induced liver toxic rats. The chloroform and ethyl acetate extracts of EM were selected for the investigation. The dose was selected by using OECD423 guidelines. The paracetamol intoxicated rats were elevated the liver functional parameters like serum SGOT, SGPT and ALP levels and also triglyceride and total cholesterol. These elevated parameters were significantly lowered in chloroform and ethyl acetate extracts of EM pretreated rats when compared with silymarin. However the antioxidant markers including CAT, SOD, GSH and GPx were significantly increased in EM extract treated rats when compared with paracetamol induced toxic rats. It revealed the plant extracts of EM has significant hepatoprotective activity. Further, this research will useful for the isolation of active principles from EM and determining its molecular mechanisms.
