I think a big problem is that "juices" or herbal liquids are not very well regulated. One person's juice may be made in Hong Kong, another person's juice may be made in Massachusetts. One has no idea what is exactly in the juice. It could have worked on your ferret ; it may not work on another ferret. It would have ben nice to know what was originally wrong with the ferret. I'm assuming the veterinarian who approved it has asked colleagues about this and maybe not heard of anything bad. I'm always kind of skeptical (as a retired pharmacist) of "herbal" meds -- even though that's the way pharmacy started -- with herbs. Not sure I want to go back to those "good ole days". So I looked online and did not find anything directly, so went to PubMed (as Sukie did) for info on Aloe juice and ferrets. Nothing re ferrets and Aloe/ Aloe juice. I ended up looking at Aloe vera in rats, toxicity, effects, etc. There are a few benefits to Aloe - some instances where it prevented tumor growth in rats (but the tumors were artificially induced): Corsi MM, Bertelli AA, Gaja G, Fulgenzi A, Ferrero ME. The therapeutic potential of Aloe Vera in tumor-bearing rats. Int J Tissue React.1998;20(4):115-8. PubMed PMID: 10093794. It also protects rats (I love white ratties - if I didn't have ferrets I'd have pet rats again) from the effects of Arsenic poisoning: Protective value of Aloe vera against some toxic effects of arsenic in rats.

"Phytomedicine describes aloe as a herb which has anti-inflammatory, anti-proliferative, anti-aging effects. In recent years several cases of aloe-induced hepatotoxicity were reported. But its pharmacokinetics and toxicity are poorly described in the literature. Here we report three cases with aloe-induced toxic hepatitis. They (5 people) had taken aloe preparation for months. Their clinical manifestation, laboratory findings and histologic findings met diagnostic criteria (RUCAM scale) of toxic hepatitis. Upon discontinuation of the oral aloe preparations, liver enzymes returned to normal level. Aloe should be considered as a causative agent in hepatotoxicity." 2. <http://www.ncbi.nlm.nih.gov/pubmed/17726067> Ann Pharmacother. 2007 Oct;41(10):1740-3. Epub 2007 Aug 28.

Case Summary: A 73-year-old female was admitted to the hospital for acute hepatitis. Extensive laboratory testing did not reveal the cause of the patient's disease. She was asked multiple times whether she was taking any home medications, which she initially denied. It was only after an extensive medication history done by a clinical pharmacist that the patient admitted to using oral aloe vera capsules for constipation. Upon discontinuation of the oral aloe vera, liver markers of hepatotoxicity returned to normal levels. There is one good effect mentioned in the PuMed search - a Chinese study "Preliminary evaluation: the effects of Aloe ferox Aloe arborescens Miller on wound healing. <http://www.ncbi.nlm.nih.gov/pubmed?term=%22Jia%20Y%22%5BAuthor%5D> Jia Y <http://www.ncbi.nlm.nih.gov/pubmed?term=%22Zhao%20G%22%5BAuthor%5D> Zhao G <http://www.ncbi.nlm.nih.gov/pubmed?term=%22Jia%20J%22%5BAuthor%5D> Jia J. Source RunHua Functional Chemical Research Institution, Beijing 100083, China. [log in to unmask] They did seem to indicate that use of aloe vera juice on the skin might convey benefits with wound healing. I think the problem is that health food products are not monitored the way that human meds are, so it could be that there is some other component in your "juice" (maybe something that makes the ferret pee more and lose fluid?). However who knows what is actually in the product -- plant and fruit "juices" do not have to be regulated like pharmaceuticals. There is no way to know how the original product has been altered by extraction, or what kind of aloe has been used. That's the difficulty with herbal meds made (usually oversea). One one site <http://www.ncbi.nlm.nih.gov/pubmed/17613130> there is a "Final report on the safety assessment of...various aloe extracts..." and gives the good and bad effects If anyone else is thinking of using using aloe extracts give that article a read first. Finally, (hindsight is always 20/20!) I'd rather have gotten a blood panel done when the ferret originally got the problem, that way you could have found out what the cause was. When you stopped the aloe treatment and she bloated up, you could also have asked the vet for a blood panel and maybe had another chance to find what the original problem was.
