I want to do a second dose the next day as in Hulda Clark 's book, pg 585, it says to take a second dose of the oil mixture (1/2 cup) the next morning after the first dose of epsom salt. But she says the 2nd dose is 1/2 cup of the oil mixture. What does this mean grapefruit juice vs oil? 1/4 cup each? Not sure what it means. Anyone?
