My invention relates to improvements in _a
method of manufacturing an auxiliaryagent for
‘ drinking medicines such as cod-liveroil, castor
oil and other disgustful medicines, and its ob
5 Ject is to provide an auxiliary medical agent
which produces innumerable number of small
bubbles of stable nature in water for facilitating
the drinking of castor oil etc. without disgustful
cines give disgustful feeling to patients. It is
very desirous to provide some agent to cancel
such disgustful odour or unpleasant. taste and

or mouth. The present invention is to provide
a very conveniently applicable agent for produc
