This brand i have says external use only.
No instructions for internal use.
Other brands i have used have internal instructions.
I popped down to the health food store and bought some, just to be on the safe side,
I have used the health foods store Epsom Salts
before without a problem.
Since this my hubby first flush i want make darn sure, he gets the right stuff.
Thanks for the info
