Abstract: Medicinal plants are gaining much interest because of their use to treat and cure common as well as chronic diseases. The study on medicinal plants started with extraction procedures that play a critical role. A wide range of technologies with different methods of extraction is available nowadays. These techniques are conventional (traditional using from long ago) and Modern (developed more recently). The conventional extraction methods use solvents and require long extraction time whereas modern extraction methods have also been applied in natural products extraction. The modern extraction methods are complex, not easily available and costly whereas Conventional extraction methods are simple, easily available and low cost. A domestic application of conventional extraction is quite familiar to everybody in daily life from the making of coffee or tea at home. It is very crucial to develop effective and selective conventional extraction methods so that practitioners and researcher inspire and improve efficiency. This review presents a detailed description of the various Conventional extraction methods for better understanding and summarizes the potential, to help evaluating the suitability and economic feasibility of them. A comparison of the performance, advantage and disadvantage of these methods is also presented.
