Undigested food particles are often responsible for allergic reactions... especially if you have a leaky gut...this might be triggering the eczema. Ooooh...I hate to see you using this stuff for three months! Weakened bowel tone and disrupted peristalsis can occur in as little as 1-2 weeks with regular use of laxative herbs...not good! If you can't return it...maybe you could mix it with plain psyllium to at least 'dilute' the laxative effect... although you'll end up with enough colon cleanser for several years. Definitely space the shakes and food more...at least by an hour...and also take digestive enzymes with every meal...double up if you're eating something not-so-good for you.
