GASTRON 



AT THE THRESHOLD 



To gastric juice Nature assigns the role of a powerful antiseptic. 



GASTRON, an extract of the actual tissue juice of the entire stomach 

 mucosa, contains all the soluble, the activable constituents of the gas- 

 tric juice itself in a carminative agreeable solution with 0.25 per cent 

 hydrochloric acid, organically bound. 



At the threshold of the digestive tract Gastron may be utilized as a 

 physiological recourse against fermentative dyspepsia, to supplement 

 and fortify impaired digestion. 



Gastron is alcohol free.
