The present work deals with the Gas chromatography mass spectroscopic study of a Unani drug, Dawa - Ul –Meda, which is prescribed for weak digestion as a good appetizer. The medicine was bought from Unani medicine vendor at Chennai and was processed suitably to be analysed by GC MS process. The profile showed many molecules such as Succinic acid, 4-methoxy-2-methylbutyl octadecyl ester, Trichloroacetic acid, undecyl ester, trans-2-methyl-4-n-pentylthiane, S, S-dioxide which have wide range of medicinal roles. These roles could contribute to the appetizing role of Dawa-ul-Meda
