I have never had anything I could say is a noticable health effect from herbal teas or tinctures but noticable effects are hard. I take fish oil pills because it has a noticable effect on my dry eye and I hope the omega-3's and vitamin and such help. I take diosimin because it has a noticable effect on my hemroids but its supposed to help otherwise vascularyly and I hope it will be more helpful in other ways. I could drink teas with Buchu Leaf but its pricey and the pills are cheaper. Would love to drink the tea instead though. I have had other things I have taken with only knowing they are theoretically good for me but I can't say for sure from my day to day.
