Nutrition and herbal medicine play an integral role in promoting health.
Herbal medicines include herbs, herbal materials, herbal preparations and finished herbal products, that contain as active ingredients parts of plants, or other plant materials, or combinations (WHO 2000).
Herbs are crude plant material such as leaves, flowers, fruit, seed, stems, wood, bark, roots, rhizomes or other plant parts, which may be entire, fragmented or powdered (WHO 2000).
Herbal preparations are the basis for finished herbal products and may include comminuted (particles or fragments) or powdered herbal materials, or extracts, tinctures and fatty oils of herbal materials (WHO 2000).
Finished herbal products are herbal preparations made from one or more herbs (WHO 2000).
Traditional use of herbal medicines refers to the long historical use of these medicines (WHO 2000).
Traditional medicine is the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness (WHO 2000).
