Jethro Kloss book?

Have any of you read the Jethro Kloss book "Back to Eden"?
The original edition was published in 1939 and has the liver/gb flush in it the same recipe that that Hulda Clark uses. Kloss states it should be done for 3 days and that you can also use 2TBSP OO (Olive-Oil) and 2TBSP lemon juice one hr. before meals for 3 days. I did my 6th flush yesterday, no stones yet I know they are in there. Very disappointing. Tweet
