Do you think this is credible?

I came upon this site that sells this blood cleanser that's suppose to help clear acne. I want to get this for my brother since he doesn't want to try liver flush. Can you check this product out to see if it's from a reliable source. http://www.banyan-botanicals.com/prodinfo.asp?number=1211&variation=&aitem=3&...

Can you please tell me what you think about it. I value you opinion so it would mean a lot to me to get your advice! Thank you so much for all you have done! Have a great day!
