What is the proper way to use OS-1?
There is no set way to use OS-1. Any amount suitable for the person’s
condition can be consumed, based on the usage guidelines. For people
who can drink fluids, there is no problem with drinking the entire
amount of OS-1 at once, rather than a little at a time.
However, when there is vomiting, OS-1 should be consumed a little at a time because drinking a lot at once may cause more vomiting.
