amount of water in an earthenware pot and other vessels to make decoctions. Polyherbal formulations, such as decoctions, have long been used in Ayurveda to treat a variety of ailments.
Chapter 3 discussed the therapeutic aspects medicinal plants and herbs for the management of vari­ous zoonotic diseases. Ethnoveterinary medicine is a branch of ethnobotany concerned with the study of traditional remedies. Ethnoveterinary methods are as old as the domestication of numerous livestock species when it comes to animal healthcare. For most of history, the growth of veterinary botanical medicine, the oldest kind of veterinary medicine, has followed a parallel path to that of human medicine. Herbal medicine has experienced a variety of conceptual modifications over time, yet its tone has stayed mostly same from antiquity to the present.
Chapter 4 describes the most important plant extracts and their bioactive compounds which determine the antibiotic activity. Pharmacological assays performed for each plant extract are presented, includ­ing the minimum inhibitory concentration (MIC) as the most used experimental method to determine antimicrobial activity. Also, there are presented the associations between antibiotics and plant extracts that have shown synergistic antibacterial activity against antibiotic-resistant bacteria.
Chapter 5 describes common neurodegenerative diseases such as Parkinson’s, Alzheimer’s, and Huntington’s diseases and cognitive disorders originating from these are among the age-related dis­eases with the highest mortality rate. Our lifestyle, especially our eating habits, has effect on neuronal survival. New data show that improving dietary habits provides successful results in the prevention or treatment of diseases. The effective role of bioactive components on neuronal survival helps develop new therapeutic approaches.
Chapter 6 discuss the studies (in vitro or in vivo) reporting or suggesting the gut microbial effect on different phytochemicals. The gut microbiota plays an important role for host nutritional, physiological, immunological functions like food digestion, vitamin production, protection of gut integrity, regulation of host immunity and disease pathogenesis. Dietary phytochemicals are important factor to shape and change the human gut microbiota composition in diversity and abundance context. On the other hand, the microbial community of the gut provides a broad range of enzymes to host which are different from its own resources. This enables human gut microbiota to affect and direct the biosynthesis and metabolism of many bioactive compounds. Bioavailability of phyotchemicals is important to benefit from health conferring effects of these compounds.
Chapter 7 discusses the gastrointestinal diseases and their management using medicinal plants and bioactive compounds. This chapter also present some of the medicinal plants that are used to treat and minimize signals of GI disease pathogenesis. Gastrointestinal (GI) diseases are those that affect the digestive tract. This may include sections from the esophagus to the rectum, and the liver, gallbladder and pancreas associated digestive organs. Gastrointestinal diseases may be acute, chronic, or recurrent. Natural products show the potential ability to treat the causes and decrease the GI tract production systems.
Chapter 8 briefly highlights the current status of commercialized phytochemicals used as anticancer drugs along with mechanism of action of some important drugs. Cancer is one of the most deadly dis­eases caused due to abnormal division of the cells. Researchers are facing major challenge for finding the effective treatment of the cancer. Various methods of cancer treatment are chemotherapy, surgery, stem cell/bone marrow transplant, radiotherapy, hormone therapy and anticancer drugs. The anticancer drugs may be natural, semi-synthetic or synthetic in nature. The most widely used anticancer drugs are the phytochemicals isolated from the plants of their semi-synthetic analogues. So the research focuses on the isolation and identification of the bioactive compounds from natural sources as a potent anticancer agent.
