Since long all the pharmaceutical manufacturing industries are developing medicines using the animal resources. But these resources are scarce and cannot meet the growing requirements of medicines. Hence, pharmaceutical engineering requires the alternative for these animal resources. Therefore biotechnological plants are concentrating more on botanical sources for developing medicines and future drugs. According to recent surveys, plants can be used to extract therapeutic proteins and provide an efficient system to deal with the increasing demands.

With the introduction of new and emerging techniques like genomics and genetic engineering, these botanical sources are made possible to be utilized as raw materials for bio-medicines. These sources can be used to manufacture a number of pharmaceuticals and anti-infective agents like vaccines, antibodies, hormones etc. Botanical sources have found to possess immense potentials for industrial scale productions of medicines.

Biotechnological plants properly implements the guidelines on the suitable selection of host plant and gene-expression system. These guidelines include the precautionary measures to be taken during all the drug related activities for the proper safety of workers and other members. Adequate facilities including the clean rooms and safe working environments are also included in these guidelines.

Pharmaceutical manufacturing industries and biotechnological plants conduct seminars and workshops with numerous machineries such as ultra-filtration units, bio-reactors, fermentors, storage tanks, stoppering and capping lines, media and buffer production systems etc. As these plants deal with the production of active and useful medicines, cleanliness and hygiene facilities forms an inevitable part of their infrastructure. These plants have contributed a lot to medical world and are still thriving hard to make this world disease-free.
