Advice needed on Stone Free, Bupleurum and Bitters - what to take and when

Hi,

I am planning to do my second Liver Flush next weekend and have purchased the stone free, bupleurum and bitters to help break up the stones and detox my liver, and I plan to take malic acid (as I can tolerate apple juice).

I can't find any info on whether I can take the stone free at the same time as bupleurum and the bitters or if I should alternate?
I would be grateful for some advice as I dont want to make things worse.

Thanks
