Remarks

The facts stated under B would suggest its use as an ex-application in psoriasis, ichthyosis, and other affections characterized by excessive epithelial formation.

Internally, its use is advisable in cases requiring a stimulating antacid. It should not, however, be continued for any great length of time, for, although at first exciting the digestive and assimilative functions, it, if given in excess, enfeebles them.
