Traditional knowledge" is employed to mean knowledge, innovations and practices of indigenous and local communities embodying traditional life-styles; the wisdom developed over many generations of holistic traditional scientific utilization of the lands, natural resources, and environment. It is generally passed down by word of mouth, from generation to generation and is, for the most part, undocumented. Traditional knowledge is valid and necessary, and awaits its currently relevant wider application for human benefit. National Institute of Science Communication and Information Resources, CSIR felt a need to document the recent developments and the information bygone in this area in the form of an interdisciplinary periodical. The Indian Journal of Traditional Knowledge will carry original research papers, review articles, short communications, etc. concerned with the observation and experimental investigation of the biological activities of the materials from plants, animals and minerals, used in the traditional health-care systems such as Ayurveda, Siddha, Yoga, Unani, Naturopathy, Homoeopathy, Folk-remedies, etc. As validation of indigenous claims it will cover Ethno-biology, Ethno-medicine, Ethno-pharmacology, Ethno-pharmacognosy & Clinical Studies on efficacy .
