RsiParasara was one of the six disciples of Maharsi Atreya and a co-student of sage Agnivesa. He, too, wrote a treatise on medicine but is not available now.
The word Parasara means a posthumous son, but we have no evidence to show that this Parasara was posthumously born. Medical authors belonging to various ages have quoted substantively from Parasara. He was one of the Rsis invited by Romapada to learn the science of the treatment of elephants. In Hasti- Ayurveda, a treatise on the treatment of elephants, Parasara is referred to as under:
�Parasara, Acuda, Matanga and Urmimali (were also invi�ted) � H. A H. 28.
A treatise called Takra-kalpa, the pharmaceutics of buttermilk is also ascribed to him. We give below a few specimen quotations from him found in other medical works of repute.
Dalhanawhile commenting on Susruta Samhita says:
Satshabdais used to signify the six treatises on medicine as composed by Agnivesa, Bhela Jatukarna, Harlta, Ksarapani and Parasara.
Dalhana quotes Parasara
Vagbhatamentions that each of the disciples of Atreya has composed a treatise Arunadatta, while commenting on this line makes it clear by mentioning the names of each author, Parasara being one of them. This commentator quotes Parasara at various places e. g. in the description of various kinds of rice.
The other commentator of Vagbhata, Hemadri, in his comm�entary Ayurvedarasayana quotes Parasara:
Cakrapani quotes him as under in his commentary Ayurveda-dipika
Sivadasain his Vyakhya-kusumavall quotes him in several places.
Parasara'sworks have long fallen into oblivion and have shared the fate of many a learned work that has probably been lost for ever. All we learn about his works is from the quotations found in other works. That medical authors of repute have quoted him proves that he must have been held as an authority of no ordinary repute in their times.
