a friend of mine ended up taking some intense antibiotics after a dog bite a few months ago, and her digestive system seems to have been ravaged by them. she's been taking acidophilus for a few weeks now to try and get things back in balance, but hasn't noticed much of a difference. i've told her she should see her doctor again, and make sure she doesn't have colitis or something else going on. can anyone suggest any cleanses she should do or other home remedies? thank you!
