ABSTRACT
This chapter describes the information on medicinal plant uses, the chemistry of medicinal plants, natural products, food chemistry, and natural products, with the purpose of establishing a relationship between the chemistry of medicinal plants, foods, and natural products. According to the information reviewed, the main link shared by natural products that include plants and some foods is the content of phytochemical compounds, and many of them have the capacity to treat or prevent one or more diseases. In addition, the verification of its functionality has been made more and more frequently by the scientific community interested in the development of functional foods; so, the search for new molecules with high biological potential continues to increase.
