Conservation and Cultivation of Medicinal Plants – Summary

Unit II focuses on the cultivation, collection, processing, and storage of drugs of natural origin, which are essential steps in ensuring the quality and efficacy of herbal medicines. To begin with, it explains the methods involved in the cultivation and collection of medicinal plants, emphasizing the importance of proper agricultural practices for achieving high yield and potency.

Furthermore, the unit discusses the factors influencing the cultivation of medicinal plants, such as climate, soil type, altitude, rainfall, and light exposure. These environmental conditions play a vital role in determining the quality of phytochemicals present in plants.

In addition, the role of plant hormones, such as auxins, gibberellins, and cytokinins, is explored along with their applications in enhancing growth, yield, and secondary metabolite production in medicinal plants. These bioregulators are widely used to manipulate plant physiology for commercial benefit.

Moreover, advanced techniques like polyploidy, mutation breeding, and hybridization are discussed in the context of improving the genetic traits of medicinal plants. These methods help in developing new plant varieties with enhanced therapeutic properties.

Lastly, the unit highlights the importance of conservation of medicinal plants, especially endangered species, to maintain biodiversity and ensure sustainable use of natural resources for future generations.
