I agree with Garcia. Read Dr. Hulda Clark s liver cleanse. I did this and I was amazed that stones actually came out of my body. They covered the entire top surface in the toilet.... Some of them an inch long.. I think this was caused due to Leaky Gut from a horrible Candida infection I had.

Also, if you do the cleanse (do a few of them or until you do not see any stones) and you still have dark circles you may have Candida (have you been on long term Antbiotics or Broad Spectrum? I was on 6 months total ranging from mild to very strong broad spectrum Antibiotics from my crazy doctor who still doesnt believe they can harm you....) The quak almost killed me. Went to emergency twice as my lymphnodes started to swell all over.... Nothing turned up.. Go figure.... The Candida was leaking food into my blood stream causing my liver to get clogged up and my immune system to go crazy......... Sad story)If you have been on them for a while Candida might be a possibility.

Check with an allergist. You maybe allergic to something in your home. i.e cats, dogs, perfume, dust.
