I did a gallbladder flush last year. I got lots of little soft green blobs come out. They could have been as a result of taking the oil + grapefruit juice. I have read around the subject and still not sure whether they are stones or a mixture of the ingredients I took. However, for about 2 years the colour of my stools were yellowy and after were a healthy brown colour for atleast a few weeks.
Before the test I took 2 malic acid supplements 3 times a day for a month. Malic acid is said to dissolve gallstones. Malic acid comes from apples, of which most is in green apples. The day before the flush I did an apple juice fast all day long also. This could have explained why they came out in little blobs. I used the Hulda Clark method for the gallbladder flush.
