1. INTRODUCTION

The Technology Protection System (TPS) or “Terminator Technology” as it has been called, allows plant breeders to genetically modify and protect their crop rights so they produce seed for one generation only. TPS was co-developed by the US Department of Agriculture (USDA) and Delta and Pine Land Company in 1998. They received U.S. Patent 5723765 entitled “Control of Plant Gene Expression”. The patent was based on research conducted under a Cooperative Research and Development Agreement (CRADA) between Delta and Pine Land Co. and the ARS USDA. The CRADA was signed in 1993.

The prolong taking of excessive salt causes profound nutritive changes to take place in the system, and there arises not only the symptoms of salt retention as evidenced by dropsies and oedemas, but also an alteration in the blood causing a condition of anaemia and leucocytosis. There seems also to be retention in the tissues. It is a great remedy for certain forms of intermittent fever, anaemia, chlorosis, many disturbances of the alimentary tract and skin. Great debility; most weakness felt in the morning in bed. Dry mucous membranes. Constrictive sensation throughout the body. Great weariness and weakness. Oversensitive to all sorts of influences. Hyperthyroidism. Goiter, Addison's disease. Diabetes.

According to Dr. E.B. Nash, Nat Mur is one of the best homoeopathic remedies for anemia. This anaemia can be caused by loss of fluids, by menstrual irregularities, by grief or mental diseases. The patient is pale, emaciated and in spite of eating very well he is anaemic. He suffers from a throbbing headache, soreness while climbing steps, exhaustion or physical exertion, constipation to some degree and overall depression. Some women have scanty flow of blood during menses.

Stains are inevitable in histology to impart variable colours to different tissue components. In this domain, hematoxylin (H) and eosin (E) dyes are the dominant stains. According to an estimate nearly 2.5 million slides are stained with H & E each day, reflecting its enormous use in histology laboratories. Hematoxylin is a natural dye, extracted from bark of logwood (Haematoxylon campechianum), whereas eosin is a synthetic dye. The journey of using natural dyes in histology began with A. Leeuwenhoek (1673) who used “saffron”, an extract of saffron crocus. It continued until the systematic studies of C Weigert, J Gerlach, P Ehrlich and H Gierke to the second half of the 19th century and then this filed became subdued by the emerging era of synthetic dyes for their effective tinct. Today most of the stains used in histology are the synthetic dyes. Often, these dyes need further treatment with chemicals to formulate the final working solutions. Synthetic dyes are efficient, but may pose serious health hazards. The awareness on such hazards even has gone to an extent of withdrawal of some of the dyes from histological techniques. Frequent exposure to these chemicals constantly affects the health of the laboratory technicians, pathologist and mainly those working in the laboratory.
Therefore, an era has triggered on the current day, to seek for use of the natural herbal dyes in histology. Despite various shortcomings with use of natural herbal stains, they can still be sought as an analogous to the conventional stains. The concern for safety, cost-effective, eco-friendly, biodegradability and local availability is driving the quest to explore the abundant local plant resources for this purpose. The precise research on various parts of the plants such as stems, leaves, flowers, fruits, roots and seeds used for dye extraction in our laboratory to stain the cell cytoplasm replacing the conventional eosin stain are chronicled in this documentation.

Various methods are employed to dry flowers and foliage. The method adopted for drying depends largely on the character of the plant, that is to say whether the plant is glabrous, succulent or not succulent, hardy or delicate in nature. The suitable method for drying any given plant has to be studied elaborately. However, the different methods of drying are described broadly in this and consequent chapters.

The major drawback of dried arrangements and other dry flower products is that they are dull and lack the brightness of fresh flowers. To overcome this problem, flowers are bleached and dyed. This enhances the visual appeal of the product. Both chemical and natural dyes can be used. Squires (1971) reported on the use of various types of paints to colour dried foliage and flowers using brushes or by dipping and spraying. Enamel paints, interior paints, poster paints and tube paints could be employed for this purpose. Tampion and Reynolds (1971) explained the three ways by which dyeing can be carried out for fresh flowers. They are as follows:

1. Introduction

Antioxidants are considered an important class of nutraceuticals which are associated with health improving properties. Antioxidants are compounds which when present in foods at concentrations lower than an oxidizable substrate, markedly delay or prevent the oxidation of substrate (Halliwell, 1999). They are increasingly applied in food systems to retard the oxidation process, particularly in lipid containing foods (Droge, 2002; Lee et al., 2004). The commercially available solutions to counter food oxidation are predominated by synthetic antioxidants such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT) and tertiary butyl hydroquinone (TBHQ), among others, which are increasingly rejected by consumers and legitimized by regulators due to long term health implications (Park et al., 2001). As a consequence, the development and utilization of natural antioxidants as alternatives to synthetic ones have attracted global interest among researchers.

The use of spices and herbs in foods was known since ancient times to modify or to improve the flavor. However, the antioxidant properties of only some of the spices have been recognized. Different spices and their extracts such as turmeric, ginger, fennel, rosemary, and sage, among others, are reported to possess very high antioxidant properties, owing to the content of biologically active compounds, which enables their food application (Madhavi et al., 1996). Exploitation of natural antioxidants in consumer goods is increasingly accepted and will gain momentum due to the rise of green consumerism. In this chapter, an attempt has been made to provide an insight into natural antioxidants and colors. Beginning with the source distribution of natural antioxidants, followed by review of extraction methods for their isolation from plant based matrices and bio-preservative properties in vegetable oils to delay rancidity. Lastly, a thorough collection of literature pertaining natural colors has been presented to potentiate the application of clean label ingredients in food systems. The application of natural antioxidants and colors in food products can vouch the food safety with value addition in terms of their nutraceutical properties.

Introduction

Fruits contain various beneficial compounds that possess biological activities and can be used as pharmaceutical nutraceutical products. Most of the fruits contain polyphenolic components that can promote antioxidant potential on human health. Wild Blueberries, strawberries, plums, oranges, grapes, cherries and mangoes are rich in antioxidant. Additionally, anti-inflammatory, antibacterial, antifungal and chemopreventive effects are associated with the various fruits. Besides polyphenols, other compounds such as xanthones, carotenoids, saponins also exhibit health effects. Fruit consumption is considerably increasing in the daily diet because they supply high levels of biologically active compounds that impart health benefits beyond basic nutrition. Fruits provide an optimal mixture of antioxidants such as vitamins C and E, polyphenols and carotenoids, vitamins, phytoestrogens, glucosinolates and anthocyanins. Diets rich in fruits may help to delay the ageing processes and reduce the risk of certain types of cancer, cardiovascular diseases and other chronic diseases. The combination of vitamins, minerals, phenolic, antioxidants and fibre seems to be responsible for these effects. The most dietary components in fruits acting as antioxidants are fibre, polyphenols, conjugated isomers of linoleic acid, D-limolene, epigallocatechin, gallate, soy protein, isoflavones, vitamins A, B, C and E (group of tocopherols), calcium, selenium, chlorophyllin, alipharin, sulphides, catechin, tetrahy-drocurecumin, seasaminol, glutathione, uric acid, indoles, thiocyanates and protease inhibitors.

Introduction

Pulses are annually grown leguminous crops that yield one to twelve grains/ seeds within a pod, and are often promoted in diet owing to their low cost and many beneficial nutritional effects (Craig 2009). The United Nations general assembly has declared 2016 as the international year of pulses (Oyeyinka et al. 2016). The Food and Agriculture Organization (FAO) describes pulses as the crops that are harvested only for dry grain. This definition excludes crops that are harvested green as food sources (such as green beans and green peas), crops that are used only for sowing purposes (such as alfalfa and clover) and crops used primarily for oil extraction (such as peanuts and soybean). India is the largest producer (around 25%) of pulses in the world and the Indian subcontinent covers the leading area in terms of consumption of pulses. It was also suggested that India can also increase the production output by 30%, considering a rise in government support prices for stimulating the growth of pulses and in case of a normal monsoon season (FAOSTAT 2008). The mainly grown pulses in India include mungbean (green gram), chickpea (Bengal gram), urd bean (black gram), lentil (masur), pigeon pea (arhar), cowpea, horse gram and peas (Tiwari and Singh 2012). In the western countries, nowadays pulses are one of the preferred food sources of the population, owing to ideological reasons and interest in vegetarian diet.

Introduction

Functional elements are non-conventional biomolecules in foods that have the ability to modulate one or more body metabolic processes or pathways, leading in health advantages and well-being promotion. Research has demonstrated a connection between food, health and well-being functional elements. Consequently, functional elements have health-promoting roles connected with multiple progressive steps at various phases of disease control, from initiation to growth. They can therefore be implemented efficiently in disease therapy and prevention. Therefore, the borderline between food and medicine is becoming very thin at a moment when the role of a healthy diet in stopping non-communicable diseases is well recognized. Functional elements include plant-derived, non-nutritious and biologically active chemicals that operate in the body to avoid certain non-communicable diseases from occurring.

Food contains over 900 phytochemicals. One fruit or vegetable serving (about 120g) can contain as many as 100 distinct phytochemicals. Previously, functional elements were believed to happen predominantly only as phytochemicals in plant products including whole grains, fruits and vegetables. However, in animal goods such as milk, fermented dairy products and cold water fish, probiotics, conjugated linolenic acid, long-chain omega-3, −6 and −9 polyunsaturated fatty acids and bioactive peptides are also discovered. Usually, functional elements happen in various forms in food such as glycosylated, esterified, thiolated or hydroxylated materials. They also have numerous metabolic operations that enable positive impacts in the body on several illnesses and target tissues (Balic et al. 2020).

Definition of Disaster

A disaster can be defined as a sudden or catastrophic event that causes significant damage, destruction, and disruption to human life, property, or the environment. Disasters can be natural, such as earthquakes, hurricanes, floods, wildfires, or they can be human-made, including industrial accidents, terrorist attacks, or technological failures.

Disasters often result in the loss of lives, injuries, displacement of people, infrastructure damage, and the interruption of essential services like electricity, water, and communication systems. They can have long-lasting impacts on communities, economies, and the environment.

Governments, organizations, and communities implement disaster preparedness, response, and recovery strategies to mitigate the effects of disasters, protect lives and property, and facilitate the rebuilding and restoration of affected areas.

It is a well known fact that natural disasters strikes countries, both developed and developing, causing enormous destruction and creating human sufferings and producing negative impacts on national economies. Due to diverse geo-climatic conditions prevalent in different parts of the globe, different types of natural disasters like floods, droughts, earthquakes, cyclones, landslides, volcanoes, etc. strikes according to the vulnerability of the area. India is considered as the world’s most disaster prone country. It has witnessed devastating natural disasters in recent past like droughts, floods, cyclones, earthquakes, landslides, etc. 

Introduction

The natural hazards like floods, cyclones, droughts, landslides and earthquakes are not rare or unusual phenomenon. India is among the world’s most disaster prone areas and a large part of the country is exposed to such natural hazards, which often turn into disasters causing significant disruption of socio-economic life of communities leading to loss of life and property. It would not be considered as a disaster unless it resulted in actual damage to human life or property. According to data accumulated over past 25 years, natural disasters in Asia accounts for about 40% of the world’s total disasters while the death toll ratio is about 50% and the number of people affected is about 90%. The latter figure is about 2.2 times the ratio of number of occurrences in Asia. The figures vary widely over the decades, a result that can be attributed to a few particularly terrible disasters. Such as the 1976 Tangshan Earthquake in China, which killed about 250,000, and a series of severe cyclones that hit Bangladesh in 1970 with a death toll of about 500,000. The death toll resulting from wind and flood disasters jumped by an order of magnitude in the 1990s. But this sudden increase affected Asia’s ratio to the world total by about 15 percentage points because there was a worldwide surge in this type of disaster. Clearly, there is an extreme concentration of victims of such disasters in Asia, Another substantial increase is clear in the value of damage caused by typhoons and cyclones; it is now running at 10 times the level of the 1980s. Again, however, the ratio has remained almost unchanged, at about 40%, because hurricanes in Central and North America account for more than 50% of the world total (51.2%, 58.5%, and 54.4% in the 1970s, 1980s, and 1990s,respectively). It is sadly worth noting that there has been conspicuous growth in the absolute value of damage in both Asia and the Americas.

WHO defines Disaster as “any occurrence, that causes damage, ecological disruption, loss of human life, deterioration of health and health services, on a scale sufficient to warrant an extraordinary response from outside the affected community or area”

Introduction
A natural disaster refers to a significant and harmful occurrence caused by the Earth’s natural processes. Examples of natural disasters include floods, storms, tornadoes, volcanic eruptions, earthquakes, tsunamis, and other geologic phenomena. A natural calamity can result in fatalities or destruction of property, and usually leads to economic harm, the extent of which is determined by the afflicted population’sability to bounce back and the availability of infrastructure.
Categories of Natural Disasters/ Catastrophes
Floods
A flood is the result of water overflowing and covering land. According to the EU Floods Directive, a flood is defined as the temporary  inundation of territory that istypically not submerged in water. Flooding can occur when the amount of water in ariver or lake exceeds its  capacity, causing the water to overflow and breach its normal borders. The size of a lake or other body of water may alter due to seasonal variations in precipitation and snow melt. However, it is not considered a substantial flood unlessthe water submerges land that is utilized by humans, such as villages, cities, populated areas, highways, and farms.

Although the thriving dye industry in many countries throughout the world is now predominantly serviced by synthetic dyes, the knowledge of the plants used to produce natural dyes still survives among some dyers, who use plant dyes to some extent. Nonetheless this indigenous knowledge is rapidly being lost as increasingly less information is being passed on to succeeding generations. Thus several countries are taking steps to revitalize this natural dyes industry. In this article the history of natural dye plants is presented; several plants from selected countries, which are used in the dyeing process are documented, together with some general methods of dye production and fabric dyeing; pattern production and the chemical constituents of some of these plants. The potential for the sustainable utilization of this important ecofriendly renewable natural resource is discussed.

Natural farming is gaining prominence in India as a sustainable and environmentally friendly method for cultivating cereals and pulses. This approach eliminates the use of chemical fertilizers and pesticides, instead depending on ageold practices, natural biological processes, and locally sourced organic materials. Crops like rice, wheat, millets, pigeon pea, chickpea, green gram, and black gram are key staples in the Indian diet, and natural farming offers a promising route to enhance both environmental health and farmer well-being.
At the core of natural farming is the focus on soil health, maintained through techniques such as mulching, crop rotation, and the use of traditional inputs like jeevamrit, beejamrit, and ghanjeevamrit. These mixtures—prepared using cow dung, urine, jaggery, pulse flour, and local soil—boost microbial activity, improving nutrient absorption and resistance to disease. Cereals benefit from proper soil moisture through waaphasa (aerated soil) and mulching, while pulses, which naturally fix nitrogen, thrive without synthetic additives.
Weeds are controlled manually or with natural solutions like agniastra, and pests are managed using plant-based formulations and cow urine sprays. Intercropping cereals with pulses enhances soil fertility, deters pests, and optimizes land usage. Farmers in states such as Andhra Pradesh, Maharashtra, and Karnataka have reported better soil health, lower input costs, and increased climate resilience through natural farming. As consumer interest in pesticide-free grains and pulses rises, farmers are also experiencing better market prices. With growing institutional support and public awareness, natural farming is emerging as a strong alternative for promoting food security, environmental sustainability, and rural development in India.

Natural farming in India is steadily gaining traction across different crop categories like tubers, oilseeds, and spices, thanks to its environmentally sustainable approach. In tuber cultivation—covering crops like potatoes, sweet potatoes, yams, and colocasia—the method promotes organic inputs, crop rotation, and soil health preservation without the use of synthetic chemicals. Natural composts, green manures, and biofertilizers nourish the soil, while homemade biopesticides and pest deterrents help manage common pests and diseases. Techniques such as mulching and moisture conservation further support ideal soil conditions,
improving both the quality and yield of tubers.
For oilseeds such as groundnut, sesame, mustard, and sunflower, natural farming enhances soil fertility using organic manures, decomposed crop residues, and locally made biofertilizers. Treating seeds with cow urine or herbal solutions enhances germination and protects against diseases. Practices like intercropping and crop diversification help disrupt pest life cycles and improve soil texture. Pest control relies on natural, plant-based sprays like neem and garlic, reducing dependency on chemical pesticides while preserving beneficial insect populations.
In the case of spices such as turmeric, cardamom, coriander, and black pepper, natural farming methods offer considerable benefits. The use of vermicompost and green manuring boosts micronutrient availability essential for healthy growth. Mulching helps retain soil moisture, especially in hilly areas. Pests and diseases are controlled using herbal preparations like Panchagavya and Agniastra, which enhance plant resistance and reduce infection rates. These eco-friendly methods lead to the production of high-quality, chemical-free spices and support biodiversity and sustainability.

In natural farming, feed supplements and probiotics made from organic and locally available materials are essential for improving animal health, digestion,and immunity. These methods provide a sustainable alternative to synthetic additives and antibiotics, aligning with eco friendly farming principles.
Natural feed additives consist of mineral-rich and herbal materials that enhance nutritional intake. Common sources include rock salt, powdered eggshells, bone meal, and herbal preparations made from plants like neem, turmeric, ginger, and ashwagandha. These supplements are valuable in addressing nutritional deficiencies in standard fodder, thereby supporting various physiological functions such as metabolism, reproduction, and disease resistance.
Probiotics, which are beneficial microorganisms, help establish and maintain a healthy gut environment in livestock. They facilitate better digestion, improve nutrient absorption, and prevent harmful bacteria from taking hold in the digestive system. Natural farming relies on probiotic-rich preparations such as Jeevamrit, Amritpani, and fermented cattle urine, all of which contain lactic acid bacteria, yeasts, and other helpful microbes.
Benefits of feeding probiotics are given below:
• Enhanced digestion of fibrous feed, improving energy use.
• Strengthened immune system, reducing dependence on antibiotics.
• Prevention of common digestive issues like diarrhea.
• Increased growth and milk production in livestock.
Homemade probiotic mixtures are commonly prepared by fermenting natural ingredients such as cow dung, jaggery, and fresh cow urine under anaerobic conditions. These cost-effective and eco-conscious preparations fit seamlessly within the framework of natural farming.

Natural beekeeping emphasizes nurturing bee colonies through a diet that mirrors their natural foraging behavior while avoiding synthetic inputs. Bees instinctively collect nectar and pollen from a diverse range of flowering plants, which supply essential carbohydrates, proteins, vitamins, and minerals for their development, immunity, and productivity. In a thriving environment free from pesticides, bees meet their nutritional needs independently. However, when natural forage becomes scarce—due to seasonal changes, drought, or habitat loss—supplementary feeding may be required to maintain colony strength.

In natural farming, supplements are offered using organic, chemicalfree options such as jaggery-based sugar syrup, diluted honey from surplus or crystallized stores, or herbal infusions made from tulsi, neem, and turmeric to boost bee digestion and immunity. These methods support crucial colony functions like brood development, wax production, and honey storage while reducing stress that could lead to disease outbreaks
