This chapter deals with an overview of design and fabrication of three-dimensional (3D) scaffolds for tissue engineering (TE) applications using the electrospinning technique. A general introduction to cellulose, a short overview of sources and methodology for the production of cellulose nanocrystals (CNCs), and principles of tissue engineering and the electrospinning technique will be given. Applications for CNCs are manifold and range from super water absorbent, drug delivery, packaging, personal care to pharmaceuticals. However, in this chapter the application in tissue engineering will be discussed in detail.

The skin is among the largest and one of the most important organs in the human body. It represents the first line of defence of the body; provides protection from mechanical impacts of the environment, limits the influence of variations in the temperature, prevents entrance of chemicals and microorganisms and restricts radiation effect. Skin damage affects all skin functions; therefore, wounds can compromise patient’s well-being, self-image, working capacity and independence. Due to all mentioned, a good wound management is necessary not only for the individual but also for the community. Herbal medicines have been used to accelerate wound healing since ancient times. Recently, scientists have been able to employ scientific methods to prove efficacy of many of these herbs and to get a better understanding of mechanisms of their actions. The popularity of herbal medicines may be explained by the perception that herbs cause minimal adverse effects. Preparations from traditional medicinal plants in wound management involve disinfection, debridement and the provision of suitable environment for natural healing process. In this chapter, the field of wound healing is briefly introduced. Further, the crucial information regarding plants, which are effectively used as wound healing agents in traditional medicine are gathered.
