You used peppermint tea, not licorice tea? Licorice tea is known to be a mild laxative, but peppermint isn't known for that. Peppermint has many positive effects though, including being anticandidal and antiparasitic. My favorite tea is the Yogi Egyptian Licorice Tea. It has Licorice Root,Cinnamon,Orange Peel,Ginger Root,Cardamom Seed,Black Pepper,Clove. These are all antifungal, and most are antiparasitic. The tea tastes great.I like the way licorice root also helps my mood. I used to take St. John's Wort for that, however I became sensitive to it.

I guess if you are still releasing parasites even at 1/4 dosage then it is still doing its job. Perhaps when you stop seeing parates, you could increase the dosage back up to 1/2 dosage? The full dosage is probably calculated for someone around 150 pounds or so, and if you are closer to 100 pounds than 150 pounds then a full dosage would be quite a bit much anyway.
