In order to produce medicines and other kinds of herbs that can be taken for commercial purposes, programs for production, distribution and extensive cultivation of herbs have been started through seven Plant Research Centers of the DPR. Similarly, by developing Karnali Province as an herbal zone, the Department of Plant Resources is ready to open the door for the possibility of producing the raw material of herbs from Nepal and processing the herbs and exporting their essence abroad. For that, the work is also moving forward by certifying its laboratory with ISO17025: 2017. The National Botanical Garden has been established by Department of Plant Resources around the year 2017 B.S. It has been serving millions of students, researchers and the entire community every year. The National Botanical Garden has been developing In-situ and Ex-situ conservation of plants for research and development work and as educational garden for the various nursery students to school students to college and doctoral students. In this way, the Department of Plant Resources has been mobilizing scientists of various disciplines as manpower in an effort to study, research, cultivate and promote plants in a multifaceted manner and in the future, by making proper use of plant resources and linking it with production, it is moving ahead with its activities so that it can contribute to the gross domestic product of the state to some extent. The Department of Plant Resources is implementing its programs accordingly.
