The plant produces large numbers of chemical compounds with diverse physiological roles. The plant takes advantage of cheap and available natural resources in its surroundings of air, water, mineral elements, and solar energy to produce these chemical compounds. These compounds are called phytochemicals, in which biotechnologists are concerned with the mass production of economically important compounds. The compounds produced by the plant are generally divided into two groups, primary metabolites and secondary metabolites. In this paper, we will review what researchers have reached in the field of accurate propagation of some important medicinal plants through a presentation of several protocols used to propagate some medicinal plants that aim to mass micropropagation them or expose them to treatments aimed at increasing the production of secondary compounds that have a role when extracted in the manufacture of medicines and pharmaceuticals.
