Best astringent

White oak bark from Caring Sunshine is great. I use it for some issues I have with my stomach. Works really fast with no side effects. My order came fast and was packed well.


I ordered white oak and it came sooner than expected. Good service

Relief from anal fissures!

I've been using this product since 2010 for recurring anal fissures. Begin with full dosage of 2 per meal, and gradually cut back the dosage as the anal fissures heal. My iridologist, who also owned an herb shop, initially recommended this. I normally take 2 capsules per day when the fissures are in remission, just to keep them at bay. I've tried other brands of White Oak Bark for this condition, but this is the brand that the iridologist sold, and, also, the brand that has worked best for me.
