I was using the Clarkia for 3 days 5-7 drops 2 times a day. I had really achy flu like symptoms for 2 days and then they went away and I feel much better. I was amazed at the critters that were living in me. BUT NO MORE I won't share myself with them!!!! I am feeling so much better after feeling so bad for several years. I have more energy and alot less pain in general.
