In recent years , the interest in natural products and plant extracts is growing; and recommend- ed as an alternative source of medication, not only in developing countries , but also in devel - oped countries either . Synthetic drugs are still dominated in modern medicine , most of the synthetic drugs have serious side effects , In particular , the antibiotics that became a real dilemma , and gradually fail in front of infectious diseases . So, why physicians until now rely on these antibiotics ? And is there any competitor alternative?
