Supplement question

Hi, Shelley! I am almost to the end of a bottle of Planetary Formula Bupleurum Liver Cleanse supplements. I think my liver is congested (because ironically enough I have taken plenty of Tylenol in the past for my neck and shoulder pain...I am off of that junk now for good!) and I finally got a ton of stones and gunk out on a 4th flush. I think they helped a lot. Should I keep taking them? If so, how long should I keep doing so?

Thanks!

Gail
