Abstrllct: Ginseng (Panllx ginseng) and Ashwagandha () are widely used as geriatric tonics. Both individually have not shown any toxicity on long term administration. Study was planned to assess the safety of the combination by doing subacute toxicity study in rats with 90 days oral administration using three doses. Food consumption, body weight, haematological, biochemical and histopathological parameters were studied. There was significant increase in body weight. food consumption and liver weight. and improved haematopoesis was observed. Brain. heart, lung, liver, spleen, kidneys, stomach, testis and ovaries were normal on gross examination and histopathologically. Subacute toxicity studies in rats did not reveal any toxicity. Key words: ginseng ashwagandha subacute toxicity

INTRODUCTION In the past, a number of studies have Recently, many Chinese as well as been carried out on these for testing Indian medicinal plants have been subjected their pharmacological activities (1-4). to detailed chemical, pharmacological and Though some isolated chronic toxicity therapeutic investigations. Ginseng, a studies are reported of individual agents, Chinese medicine, alone and in combination no systemic long term subacute and chronic is being promoted as a general tonic. toxicity studies have done using a combination of the two drugs. Similarly, Ashwagandha, an indigenous medicinal , claimed to have many Therefore, in order to substantiate the properties similar to Ginseng is also in wide claim of safety of this combination, this use. particular study was planned, as subacute
