Medicinal plants are important sources for both newly developed and current medications. Most cultures in the globe, including Tibetan, Chinese, and Indian medicine, use plants directly as remedies. Researchers and medical scientists are working day and night to discover drugs for serious illnesses like diabetes, thyroid, cancer, and neurological disorders. Due to the unparalleled availability of chemical variety, natural products derived from medicinal plants, whether in the form of pure compounds or standardized extracts, provide countless prospects for novel therapeutic leads. Global interest in edible plants has increased due to the growing need for chemical diversity in screening programs and the search for therapeutic medicines from natural sources. Medicinal herbal and botanical preparations contain a variety of bioactive components. The World Health Organization (WHO) reports that 91 countries, including 12 megabiological countries, are home to almost 20,000 medicinal plants. The first steps in using the biologically active chemical found in plant resources are extraction, followed by pharmacological screening, bioactive compound isolation and characterization, toxicological assessment, and clinical assessment.
