This article contains the review of snake venom which is highly found in Southeast Asia. There are inadequate services, difficult transportation facilities and delay in medical treatment which are the main reasons for the high morality. There are number of medical plants available locally and used widely by the traditional healers, therefore must give special attention. A wide range of pharmacological properties of herbal drugs and their active principles are evaluated. However, more needs to be studied to get more results

Maranta arundinaecea is otherwise known as arrowroot. It promotes weight loss, treats diahorrea and stimulates the immune system. As Arrowroot is rich in starch, it helps in good digestion by mild laxative in regulating the bowel movement. Also it reduces stomach pain and bloating. Selenium is a semi conductor so it is used in making electrical wires. It is used in potent chemotherapy. It is an anti-cancer agent due to its invasion of apoptotic pathway and cell cycle arrest. Usually the arrow root extract is available as powder. The powder is diluted and mixed into sodium selenite solution and this combination is observed for 3 days. After 3 days, it is centrifuged and collected in a pellet form. The lactobacillus and streptococcus mutants are used for culture of organism for 1 day. The extract is tested for for anti-bacterial activity. Result- It shows the sector where it can inhibit in Streptococcus mutans and lactobacillus. Maranta arundinaecea root mediated selenium nanoparticles shows very good antibacterial activity will used in many biomedical applications is future.

Goldenseal, commonly known as yellow puccoon has wide therapeutic activity. The bioactive components present are isoquinoline alkaloids, hydrastine, berberine and canadine. Berberine is used to treat heart failure also have sedative actions, anti secretory, anti parasitic, anticancerous actions. Hence an attempt was taken to review the pharmacological actions of Goldenseal with respect to its role in dental practice.

Selenium nanoparticles have role in toxic waste removal and bioremediation. In a recent study, biosynthesis of many metal and metal oxide nanoparticles by different plant extracts was found to be stable even after wet heat sterilization process. In some studies, biosynthesis of silver, gold, and selenium nanoparticles using microorganisms and plant and parts. In this present study we have synthesized selenium nanoparticles using arrow root and analysed for its free radical scavenging activity. 20 mM of sodium selenite was prepared using 60 mL of distilled water and 40 mL of Arrowroot extract. It was kept in the shaker. Readings were taken for 3 days. Centrifugation was done at 8000 rpm. Pellet was collected and was used for antioxidants activity that is free radical scavenging activity. The antioxidant property of arrow root mediated selenium nanoparticles are comparatively higher than the standard antioxidant property. Calculations were done on the basis of reading that was obtained. This study proves that there is antioxidant activity that is free radical scavenging activity adopted by selenium nanoparticles extracted from arrow root.

Objective: The objective of this study was designed to gauge the antianxiety activity of varied extracts, namely, n-hexane, chloroform, ethyl acetate, and methanol of the flowers of Tamarindus indica using elevated plus maze (EPM) model in albino mice. Methods: Coarsely powdered tamarind was powdered and subjected to exhaustive Soxhlet extraction using n-hexane, chloroform, ethyl acetate, and methanol. Solvents were recovered from all extracts using a rotary vacuum evaporator under reduced pressure. Albino mice have ministered orally with different doses of the extracts (i.e., 200 and 400 mg/kg) and behavior was observed on the EPM. The standard (positive control) employed in the study Diazepam (2 mg/kg, P.O). Results: Results indicate that the methanol extract of T. indica flowers showed maximum and significant dose-dependent effect at 200 and 400 mg/kg on EPM, the results were just like the standard antianxiety agent diazepam (2 mg/kg). Locomotor activity evaluated with two different doses of T. indica (200 and 400 mg/kg) using actophotometer. The results were shown to be decreased in a dose dependent model compared to control. Conclusion: The methanol extract shows that the presence of polyphenols could be liable for the anxiolytic potential of T. indica. Hence, this plant could also be used as a useful antianxiety agent.
