Ashtanga Hridaya is one of the most popular Ayurveda text of Indian medical science. It was written by the famous scholar Vagbhat in the beginning of the eleventh centuary. It is already translated into English and some of the Indian vernaculars. This coupled with many technical words often makes it difficult to understand the exact significance of many passages. To remove these difficulties the author has brought out this dictionary of Ashtanga Hridaya Kosh where the technical terms used in the text have been arranged in alpha-betical order and explained by a critical and explana-tory commentary. The author has also explained these terms in his own sanskrit commentary and also given synonym in English, Latin and some of the spoken janguages of india such as Hindi, Marathi, Gujarati and Canarese. This is no doubt a valuble service to the cause of Ayurveda, for which all lovers of the science will remain grateful.
