I just researched a little about impaction and what you can do for it. Someone said you can put a few drops of mineral oil on their lips and it will soak in and act as a laxative. There is something else called Mela fix (the posts say it should be used with water as a soak----you'll have to read through the posts to find out exactly how they used it) available at wal mart. I found this information at http://repticzone.com/forums/TreeFrogs/messages/1909551.html. I have never tried this, and am not saying that you should use it. This is just info I looked up to try and help you. I have no experience treating frogs for any kind of ailment. Good luck. I hope your froggy gets better.
