Nature uses very few materials to create a bewildering variety of life forms. Same material is used in many different ways to meet vastly different needs as exemplified by collagen. Nature makes economic use of materials by optimizing the design of the entire structure to meet multiple needs. So, natural materials are self-generating, hierarchical, multi functional, non linear, composite, adaptive, self repairing and biodegradable.. The use of natural products as a biomaterial is currently undergoing a resurgence in the biomedical field. Biomaterial is used to make devices to replace a part or a function of the body in a safe, reliable, economic, and physiologically acceptable manner. One of the advantages of using natural materials for implants is that they are similar to materials, and are familiar to the body systems.
