OLIVE LEAF is not normally purcahsed by anyone who has not read the $5.95 book called Olive Leaf Extract, those that do read the book normally know to buy the powder of the whole leaf.
The strongest method is tea, 1 quart per day for 8 days, then take the powder from that point onward.
The tincture is too strong to take in large dose like the tea can be taken, so the tincture is more for bee stings and mixed in drinks, etc normaly 1 dropper per dose. A few take it by mouth 1 dropper at a time.
THERE are no set in stone doses and the best are mentioned in the book, if a person does not use Olive Leaf for the rest of their lives after reading that book, then I have no hope for them!!!!
