I may have a way to explain it.
Think of taking a remedy as giving your body a
to tell it to heal itself. The potency of the remedy is how hard you
.
Now if you poke me once you have my attention. If you poke me three times in a row (give more pellets) you still have only gotten my attention one time. If you poke me now and then poke me again 15 minutes later you have now gotten my attention twice - same as giving two doses of the remedy 15 minutes apart.
Standard directions say to give multiple pellets. Theoretically one is enough. In practice I have heard it suggested to give a few "in case one's a dud." I don't know about the veracity of that but I do know that buying one pack (three vials) of Oscillococcinum for the flu is enough for the whole family, contrary to the label instructions which would like you to buy a pack for each family member.
