Various kinds of chinese herbs have been known as to promote growth rate of animals. We investigated the growth promoting effect of the selected plants by using fish and rats as experimental animals. In a preliminary test by using fish, Eleutherococcus senticosus and Artemisia capillasis were found to be effective. Based on this result, we manufactured the mixture of plant extracts and applied this mixture to rice, named as Kiwoomi^TM. When we administered Kiwoomi^TM to rats, it was found to be effective in growth promotion. Kiwoomi^TM - administered group showed 49.3% (0.75g/kg B.W.) and 52.3% (1.59/kg.B.W.) growth promotion, respectively. On the other hand, Control group showed 46.2% growth promotion. This growth promotion was supported by increase of GH and IGF-1 level in the Kiwoomi^TM- administered group. From these results, we suggest that this functional rice could be helpful for growing children.
