Rated 5 out of 5 by from Great Supplement I started taking Dandelion Root one month ago, and I can honestly say, it does everything that I read about this product on WebMD. I feel so much better and I will continue to take this along with Olive Leaf Extract everyday. I suggest you read about it and try it and see if it works for you as well. You will see an improvement and so will your doctor.

Rated 1 out of 5 by from I've been ordering Swanson Olive Leaf Extract for years. Usually when I open a new bottle, I can smell the freshness and the pills are green. The last couple of shipments I've received the pills don't smell very fresh and they are yellow in color. They look and smell stale. I have an older bottle that is much fresher with green pills than the new bottles with the yellow pills. There is a definite quality control issue here. I won't order these again unless this big problem is addressed.
