I am sorry this answer is late - we are smack in the middle of the busy season here at HUMAWORM. Stay with the tea - you can either up or lower the amount - just listen to your body. The itching was from the toxins coming out of your skin - you are correct in that your liver is overloaded right now - this is why your skin is jumping in to help your liver remove the toxins - hence the itching.
A plain liver flush would help - the recipe is on the bottom of the F&Q page at http://www.humaworm.com
This will help the liver dump out toxins - or if you prefer - a coffee enema will do the same thing.
