(Accepted on 4 May, 2012).
The pathogenic bacteria of the human respiratory system are characterized by resistance to most antibiotics. Staphylococcus aureus and Klebsiella pneumonia are some of the pathogenic bacteria of the human respiratory system which often cause pneumonia, pleurisy and meningitis. Moreover, they are the most prominent strains of bacteria in most hospitals.
Bacterial resistance to antibiotics occurs as a result of excessive usage of antibiotics in the treatment of diseases. For that reason, it is necessary to seek for medical alternatives that are safer for the treatment of these bacteria. Alternative medicine, especially, has revealed many plants and herbs that are used in the treatment for some diseases including respiratory diseases.
