Zingiber officinale Rosc. (Zingiberaceae) - Ginger, an essential raw spice and natural medicine, plays an important role in the kitchen (a food spice) and has medicinal uses worldwide for health benefits. It is an ancient recipe of Indian systems of medicine such as Ayurveda, Unani, Siddha, and Homoeopathy. Ginger is one of the important drugs of the Ayurvedic System of Medicine, known as the universal medicine (Viswabhesaja), and found in almost all classical formulations of Ayurveda for the treatment of different diseases, and the majority of Ayurvedic prescription drugs contain ginger as one of the ingredients. The present paper highlights the use of Zingiber officinale in the Ayurveda system of medicine in India. In Ayurveda, Zingiber officinale is used both in fresh (Ardraka) and dry (Shunthi) forms. Description of the drug appears in almost all pharmacopeia of Ayurveda known as Nighantu (lexicons), Samhita (treaties), Chikitsagrantha (Compendia), and Rasa grantha (Pharmacopeia), etc. Dry ginger is one of the ingredients of Trikatu (group of three pungent spices), a famous Ayurvedic formulation for the treatment of digestive and other disorders.

In Ayurveda, fresh ginger alone or along with other drugs is used in fever, coryza, and bronchial asthma, cough, disorders due to change of place, inadequate digestion, diarrhea, anorexia, piles, oedema, abdominal disorders, fainting, urticaria, earache, and rheumatoid arthritis, etc.
