Ya there seems to be a lot of contradictory information on olive leaf then...so you may be fine with a small dose. I just remember warnings not to take olive leaf with probiotics because it would just kill them.

I know that my goats can eat a lot of olive leaf right off of the tree with no apparent problems, and I mean 100x more than we take for medicinal purposes...but goats can eat more plants than any other ruminant animal...including some plants that would poison most animals.

I know garlic is fine because I put a lot of raw chopped garlic in my homemade kim-chi and it ferments just like sauerkraut does with plenty of lactobacillus bacteria.
