Sour Mouth?

Last night, I started taking cloves, black walnut powder and wormwood tea to see if I had any significant parasites inside my body which may be a main cause for all of my health problems. After taking this stuff, my tongue has been tasting some sour taste (seems like mostly the back of the tongue).

I've now taken the mixture three times, and I especially notice it at night, after dinner. I've never experienced this before in my life. Am I the only one with this experience? Is it just detox? Could the mixture be affecting my digestion in some way, maybe releasing more HCl?
