Much of the legacy surrounding the Islamic influence on modern hospitals and science can be found in the discoveries, techniques, and practices introduced by scholars and physicians working in these hospitals between the tenth and nineteenth century. This time period was extremely important to the advancement of modern medicinal practices, and is known as one the greatest periods of development. Many of these discoveries laid the foundation for medical development in Europe, and are still common practice in modern medicine. Among these discoveries in astronomy, chemistry, and metallurgy, scholars developed techniques for medicine such as the distillation and use of alcohol as an antiseptic, which is still being used in hospitals today. Not only did these discoveries lead to lasting improvements in medicine in the Muslim world, but through the influence of early Islamic and Arabian hospitals, medical institutions around the world were introduced to various new concepts and structures, increasing the efficiency and cleanliness which can still be found in modern-day institutions.
