great to hear there is an improvement in your eczema after a dental cleanse. i am planning on removing the five mercury fillings i have. and since we are on the topic of eczema, have you considered doing doing a liver flush? i did a flush a week ago and my skin condition has improved greatly (nb. i suffer from chronic eczema). i'm planning on my second flush next weekend.
also, i have been taking wheatgrass supplements which also seems to be helping.
