Introduction: Siddha Medicine is a system of Traditional Medicine originating in ancient Sri Lanka and Tamil Nadu in South India. Traditionally, it is taught the siddhars laid the foundation for this system of Medication. Agastyar is considered the first Siddhar and the guru of all siddhars. Siddha system considers the human body as a collection of tri-humors & seven basic elements. Vatham, Pitham & Kapham are the tri-humors which are the life constituents of the human body. The equilibrium of humors is consider as health & its disturbance or imbalance leads to disease. Aim and Objective: The aim of the study is to identify the 4448 diseases according to the Siddha Literatures. Results and Discussion: 4448 diseases are mentioned in Agasthiyar 2000, Angathipatham, Noi Naadal Noi Muthal Naadal part I and Theriyar vaakadam. Siddhar Aruvai Maruthuvam book stated that Head and neck diseases are 1008. Diseases are classified according to anatomical structures of body parts, tri humors and diseases. Totally, 93 diseases are explained in all five books. In Noi Naadal Noi Muthal Naadal Part II, 51 diseases and its types and In Yugi Vaiththiya Sinthamani, 27 diseases and its types are explained in the books. Totally, 544 and 431 Number of diseases are explained in the text Noi Naadal Noi Muthal Naadal Part II and Yugi Vaiththiya Sinthamani respectively. Conclusion: This study has given quite evidence about 4448 diseases. These collected information are helpful for further studies in types of diseases.

Abstract Background Continuous and non-judicial application of synthetic insecticides to control the tea thrips, Scirtothrips bispinosus (Bagnall), one of the major tea pests in South India has led to certain undesirable issues in the ecosystem besides the presence of the pesticide residues in manufactured tea. Biological control agents are of immense importance in tea cultivation. The present study was designed to isolate Lecanicillium lecanii (Zimmermann) Zare & Gama from the field-collected cadavers of the insects/mites infected by fungi of tea growing areas of Anamallais (Tamil Nadu, South India), and to evaluate their field bio-efficacy against the tea thrips. Results Lecanicillium lecanii isolated from the tea ecosystem had been formulated into a wettable powder (WP) formulation and evaluated against tea thrips under both laboratory and field conditions. Among the several media evaluated, the PDAY (Potato Dextrose Agar + 1% Yeast powder) was found to be the best suitable medium for the growth and germination of spores. Optimum conditions for the growth of L. lecanii were found in PDAY medium at the pH 6-7, temperature 25-30°C and 90-95% RH. Exposure to UV light for more than 30 min significantly inhibited the growth of the fungus. Lecanicillium lecanii at (1 × 107 spore/ha) was found significantly effective against thrips. Fungal development index (FDI) of L. lecanii + jaggery significantly differed than other treatments. Lecanicillium lecanii at 1500g (1×107 conidia/ml) mixed in 400 l of water was effective against the tea thrips. Addition of equal amount of jaggery with L. lecanii wettable powder in the tank mixture could increase the efficacy of the mycopesticide against tea thrips. Conclusion The powder formulation of L. lecanii was found safer to natural enemies present in the tea ecosystem. After fulfilling the requirements for its registration and label claim on tea, this strain of L. lecanii could be commercialized for the benefit of the tea industry for the management of tea thrips in an eco-friendly manner.

Post Disaster

This study focuses on disaster impacts and recovery in Tamil Nadu, drawing on insights from Chennai city and Nagapattinam district. The research is part of a larger three-year project called “Recovery with Dignity”, which examines the experiences of recovery in post-disaster situations across three states in India – Odisha, Tamil Nadu, and Kerala – and explores how recovery processes represent vulnerable populations. In this report, we focus on three key disasters in Tamil Nadu: the 2004 Indian Ocean Tsunami, the 2015 South India flood, and the 2018 Cyclone Gaja. Through these events, we examine how the ways disasters and their losses are represented shape recovery outcomes. The study uses a range of data, from a review of state policies in Tamil Nadu (2005-2019), an analysis of media articles published in English and Tamil (2004-2019), to interviews with disaster-affected people and secondary stakeholders. The findings indicate that disaster responses and outcomes are highly differentiated based on how disaster-affected people and their needs and losses are represented. To enable inclusive recovery, it is necessary to recognising the heterogenous nature of disaster impacts and acknowledge different ideas of what recovery means.
