114 THE MEDICINAL PLANTS OF THE PHILIPPINES 



The bark, especially that of the root, is highly astringent and 

 a decoction of it is used for diarrhoea and as a wash for ulcers. 

 Dr. Waitz has successfully used the following formula in treat- 

 ing the chronic diarrhoea of children : 



Root bark of guava 15 grams. 



Water - 180 " 



Boil till reduced one half. Dose, a tablespoonful every 2 or 

 3 hours according to age. 



A decoction of the shoots is very useful in stomatitis, cuta- 

 neous eruptions and ulcers. Dr. Waitz advises his formula in 

 prolapsus recti of children. It is also of value as an injection 

 in diarrhoea and dysentery.
