Abstract
Background and Objectives: Human body consists of different types of organs in respect to structure and function. Continuous wear and tear occurs in these organs of the body while performing living processes and tasks. This wear and tear is inevitable. Wearing of tear is provided by nutriment. It is necessary to provide nutritive material in such form which can be utilised by the organs of the body. Methodology: This study is based on doctrines of Greco-Arab Physicians like Galen, Avicenna, Razes, Averroes etc. regarding transformation as well as incorporation of nutriments inside the body. Literature related four digestions is surveyed from various classical books and journals, for better understanding and explanation of this concept. Collected material then analysed and systematized in a comprehensive way. Observation and Conclusion: Inside the body replenishing entity i.e. nutriment gets transformed from complex to simpler form so it can assimilate into the organs of the body. This whole process of transformation of nutriment is divided into four steps called as hudhum arbaa. This process of transformation is gradual and brought about by quwwate ghādhiya (Nutritive faculty) as well as its subservient faculties.
