Herbs have a wide variety of chemical compounds that can support food quality, medicines, and biotechnology approaches. Over the years, extensive research has been carried out in genetic engineering of foods, including improving the feasibility of herbs. The story behind the herbal genetic technology relates to food allergy, the pharmaceutical industry, and of course, the growing food shortage that is the biggest nutritional issue of this century. Researchers have highlighted that in genome editing, creating synthetic biology is a good strategy. Furthermore, the production of secondary metabolites in herbs may be enhanced through genetic methods. The researchers investigated the plants’ secondary metabolic pathways as well as their genetic alterations. Yet there are some herbal remedies used in genetic engineering. This chapter begins with a discussion of our studies of functional foods and their effects on human and animal health. Next, we will highlight the importance of genome editing in herbs and methodologies. Additionally, the differences between natural functional foods and genome editing herbs will try to prove efficacy on humans and animals. Consequently, we will attempt to reveal if genomic foods have protective effects on health and particularly on pandemic diseases.

Natural antioxidant compounds have different mechanisms of treatment and prevention against various diseases due to their richest ingredients. There are several antioxidants used today, such as phytogenic ingredients, flavonoids, capsaicin, spirulina, beta-glucan, polyphenol etc. Besides the outbreak of diseases, the ability to scavenge oxidative conditions of the natural antioxidants have been notably important. Thereby, therapeutic strategies of diseases have been interested by researchers. Try to seek a kind of effects of natural antioxidants to various diseases, especially viral or pandemic diseases are being important nowadays. This chapter we’ll mention about how to viral or pandemic disease’s effects on oxidative status in both animals and humans, and what kind of phytochemical ingredients would be a positive effect on. At the same time, the latest advances about these natural antioxidant compounds and pharmaceuticals will be critically highlighted and discussed with newest literatures.

Saccharomyces is a eukaryotic organism that possesses approximately 6,000 known genes since 1996. It has long been used for food, bakeries, drinks, and therapeutics due to its many ingredients and its role in several mechanisms. Saccharomyces can be used as an experimental organism for medicinal products in the pharmaceutical industry. Particularly in public health, the use of Saccharomyces in the production of vaccines is remarkable. It has been alleviated that this yeast helps clarify the function of individual proteins in pathogenic viruses. To clarify virus life and host interactions, virus replication systems in Saccharomyces were interested in scientists. The new antiviral strategies with yeasts suggest the biological mechanism of a pathogen virus. Due to the variety of diseases and current epidemic conditions, these organisms play an essential role in prevention and treatment. This chapter will try to update Saccharomyces’ scientific discoveries with the most recent and up-to-date literature.
