With its foundation in Aristotle's Catharsis theory and its historical acclaim, art therapy is a powerful example of the healing power of artistic expression. This study examines the complex function of art-based therapies in enhancing mental health and wellbeing by synthesising a wide range of literature, from modern empirical investigations to ancient philosophical concepts. The fundamental idea behind art-based therapy is that it provides a nonjudgmental path to self-awareness and personal growth by enabling the creative expression of inner experiences and feelings. Art-based therapies include individuals in a transformative dialogue with their inner worlds, ranging from painting to music improvisation. This approach fosters resilience and agency in confronting mental health difficulties. This review acknowledges the role that artistic expression plays in the healing process and emphasises how art therapy is widely used to treat a wide range of illnesses, including Alzheimer's disease and cancer. Investigating cutting-edge media like photography and interpretive dance provides opportunities to enhance comprehension and maximise the healing power of the arts. Finally, it can be said that art therapy is a flexible and all-encompassing approach to mental health care that has significant advantages for people with a wide range of conditions and backgrounds. Incorporating creativity into therapeutic practices improves treatment results and enriches lives by promoting emotional wellness and personal development.
