i read the instructions which recommended swishing for 5 minutes. they "suggest" doing it 5 times a day. i do not do that. between the op for 20-25 minutes in the morning once a day and clay pulling in the evening- that is enough for the time.
ot - however i do use the pyrophyltte clay for a clay bath 3/4 times a week; also i do drink 1 tbls of clay with water 3-4 times daily. i intend to do this "therapeutic regimen" until after memorial day - that will make it 4 weeks; then i will evaluate myself and decide from there.
