Abstract
The aim of this introductory lecture is to review the arguments, according to which the symmetry properties of the strong interaction reveal themselves at low energies. I first discuss the symmetries of QCD, then sketch the method used to work out their implications and finally take up a few specific issues, where new experimental results are of particular interest to test the predictions.

The model for the πN interaction developed by P. F. A. Goudsmit, H. J. Leisi and E. Matsinos, Phys. Lett. B271 (1991) 290; Phys. Lett. B299 (1993) shows that the low energy data may be understood in terms of effective fields. The expansion of the resonance denominators occurring in the tree graphs of this model should yield a decent approximation for the effective Lagrangian.
