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.

Procrastination is widely recognized as a motivational problem, but its nature is still not entirely understood, especially in the work domain. Procrastination in the execution of everyday work tasks could be motivated by both mood repair and predictor of poor mood. It could also be related to task characteristics, like averseness or demands. The aim of this study is to examine the relation between procrastination, levels of self-efficacy, perceived job demands and control, and symptoms of anxiety and depression. This study was conducted on a sample of 70 teaching assistants, the employees of a small university. The data was collected using Avoidance reactions to a deadline scale, DASS, Self-efficacy scale and Job demand-control scale. Correlation results indicated that self-efficacy and perceived job control were negatively, and job demand positively related to proneness to procrastination. Furthermore, individuals with more symptoms of anxiety and depression tended to procrastinate more. Perceived job control is the single relevant predictor of delaying job-related tasks and activities. The findings clearly suggest that job control deserves additional attention when it comes to the prediction of workplace procrastination.
