The Chemistry inside Spices & Herbs: Research and Development brings comprehensive information about the chemistry of spices and herbs with a focus on recent research in this field. The book is an extensive 2-part collection of 20 chapters contributed by experts in phytochemistry with the aim to give the reader deep knowledge about phytochemical constituents in herbal plants and their benefits. The contents include reviews on the biochemistry and biotechnology of spices and herbs, herbal medicines, biologically active compounds and their role in therapeutics among other topics. Chapters which highlight natural drugs and their role in different diseases and special plants of clinical significance are also included. Part I focuses on the general aspects of spice biotechnology, structure activity relationships and the natural products that can be used to treat different diseases - such as neurological diseases, inflammation, pain and infections. This part also covers information about phenolic compounds, flavonoids and turmeric supplements. This book is an ideal resource for scholars (in life sciences, phytomedicine and natural product chemistry) and general readers who want to understand the importance of herbs, spices and traditional medicine in pharmaceutical and clinical research.

Abstract

Medications for the treatment of pain and inflammatory disorders, although effective, their chronic use and/or misuse can lead to serious side effects. In this regard, naturally-derived antinociceptive and anti-inflammatory agents have emerged as alternatives to synthetically marketed drugs. The current review covers all the nutraceuticals and phytochemicals – derived from medicinal plants– which have been reported to possess analgesic and/or anti-inflammatory effects over the period between 2018 up to June 2020.

Keywords: Pain, Inflammation, Marine organisms, Medicinal plants, Natural products.

INTRODUCTION

Inflammation is one of the responses of innate immunity to infection or tissue injury. Despite being essential for maintaining normal homeostasis, prolonged inflammation could likewise be a sign of a pathological condition resulting from chronic diseases, which could be detected by the presence of inflammatory markers [1]. The molecular mechanisms of inflammation are complicated, and they are initiated by the recognition of the allergen by germline-encoded specific pattern recognition receptors such as Toll-like receptors (TLR), retinoic acid-inducible gene-I (RIG-1)-like receptors, C-type lectin receptors (CLR), and the nucleotide-binding oligomerization domain (NOD) like receptor [1, 2]. These inflammatory responses end up with some typical symptoms, including redness,

swelling, pain, and heat [1, 3]. Activation of these receptors by bacteria triggers the release of inflammatory cytokines, which in turn mediate the production of C-reactive protein (CRP), among others, which promote the secretion of prostaglandins [3]. The latter are responsible for the symptoms of inflammation. Viral infections, on the other hand, trigger the release of type-I interferons, while parasitic infections and other allergens increase the production of histamine and interleukins. The common pathways, which play a major role in inflammation, are the NF-ĸB, JAK-STAT, and MAPK [3]. Although pain is one of the consequences of inflammation, it could also be a separate sign, even with no existence of an ongoing inflammatory process. Non-steroidal anti-inflammatory drugs (NSAIDs) and opioid analgesics are among the commonly used medications for pain treatment. However, they show many side effects, which lead to patient discomfort, especially in chronic use [4, 5]. Since the last decade, many natural products have proven efficacy for the management of pain and inflammation [2]. Herein, we report on the latest updates in the field of anti-inflammatory natural products, which have been reported over the interval between 2018 and June 2020.
