Review title: Side effects
Product review: I was a fairly long time user of this product and loved it because it was effective and, I thought, safe for extended use. Then I went for my first colonoscopy and was told by my doctor that I had Melanosis coli which is caused by using products with senna and cascara sagrada bark. She said that, if I didn't stop using the product, she would not be able to see anything on the lining of my colon due to the pigmentation changes. I have never seen anything about this in the product information and have now stopped using the product.
