Medicinal plants, regarded as invaluable components of our ecosystem, have been integral to human life and healthcare since ancient times. Their significance endures in contemporary society, primarily due to their fundamental therapeutic and curative properties. Herbalism has made extensive use of research into and practice with naturally occurring plants. No big pharmaceutical corporations showed interest in these natural compounds. Drugs for microbiological infections, cancer, heart disease, and diabetes have traditionally been the focus of smaller pharmaceutical companies, whereas larger pharmaceutical conglomerates have concentrated on screening synthetic chemicals. The medicinal value of natural substances and their derivatives have grown substantially in recent decades. Natural sources, such as plants and microorganisms, constitute the basis for around one-third of the highest-grossing medications in the pharmaceutical industry. Because of their medicinal efficacy, fewer adverse reactions, and inexpensive cost relative to alternatives that are synthesized, these items are suggested. The issues that are associated with the creation of herbal medications and the stocking of information regarding the screening of medicinal plants are discussed in this chapter.
