My favorite detoxifier is dandelion. It has been used by the ancient Chinese and American Indians for thousands of years as a liver and gallbladder cleanser. It's also been used to treat skin problems, swelling, upset stomach and heartburn. It's got a decent amount of vitamins A,B,C, and D plus it is a good source of minerals. I like to throw some leaves on salads as I enjoy the taste. It makes a great tea also.
It feels good to make use of a plant that most people consider a pesky weed.
