Pharmacognosy of Science for the Protection and Survival of Nature and Man

Elvira Kovac-Besovic*, Adnan Besovic, Azra Besovic and Salih Saracevic

Pharmacognosy as a science of natural medicinal raw materials and drugs of natural origin is a science that protects nature and affects the survival and protection of man. From the earliest times, man was exploring everything that nature provides. With the development of science and technology, research into natural raw materials, as well as those with healing activity, was perfected. The obtained results could reliably be used in official pharmacopoeia, medicine and dentistry. With the development of computer technology, there has been more detailed information on the use of natural medicinal raw materials through Phytotherapy, which is increasingly being applied.

All these studies indicate that pharmacognosic studies with the goal of using natural medicinal substances and medicines of natural origin must not be called alternative medicine, but it is the same as all other medicines that are only adapted to the nature of natural raw materials.
