To determine the larvicidal activity of various extracts of Gymnema sylvestre against the Japanese Encephalitis vector, Culex tritaeniorynchus in Tamilnadu, India. To identify the active principle present in the promising fraction obtained in Chlorofom:Methanol extract of Fraction 2. The G. sylvestre leaf extracts were tested, employing WHO procedure against fourth instar larvae of C. tritaeniorhynchus and the larval mortalities were recorded at various concentrations (6.25, 12.5, 25.0, 50 and 100 µg/mL); the 24h LC50 values of the G. Sylvestre leaf extracts were determined following Probit analysis. It was noteworthy that treatment level 100 µg/mL exhibited highest mortality rates for the three different crude extracts and was significantly different from the mean mortalities recorded for the other concentrations. The LC50 values of 34.756 µg/mL (24.475-51.41), 31.351 µg/mL (20.634-47.043) and 28.577 µg/mL (25.159-32.308) were calculated for acetone, chloroform and methanol extract with the chi-square values of 10.301, 31.351 and 4.093 respectively. The present investigation proved that G. Sylvestre could be possibly utilized as an important component in the Vector Control Program.

The herbal extracts of four traditional plants; namely leaves, fruits leaves, and seeds, were identified for their main constituents using UHPLC/QTOF-MS/MS. Then, a pharmacology-based analysis and molecular docking verification were established targeting the evaluation of each individual herbal extract for their antidiabetic/anti-obesity potential besides their safety. Streptozotocin-induced diabetic rats were used to evaluate antiobesity and insulinotropic effects against insulin (10 U/Kg, IP) and metformin (100 mg/Kg, per oral) as standard regimens.

Gymnema sylvestre (GS) contains gymnemic acids which can reversibly suppress sweet taste responses. This randomised crossover study aimed to investigate whether supplemental GS use can reduce sugar cravings, sweet food desire and consumption among adults that identify as high sweet food consumers (having a 'sweet tooth'). Participants were told three different mints were trialled to avoid bias.

Introduction: Silver nanoparticles (AgNPs) derived from natural sources have garnered significant attention due to their unique properties and eco-friendly production methods. With lung cancer remaining a major global health issue, there is a continuous need for novel and effective therapeutic approaches beyond conventional treatments such as chemotherapy, immunotherapy, and targeted therapies.
Objective: This study aims to synthesize AgNPs using plant extracts from Gymnema sylvestre, Moringa oleifera, and Azadirachta indica and to evaluate their anticancer activity, particularly their effects on gene expression in A549 lung cancer cells.
