Re: Aloe vera, is it poisonous? (was Update on Antonio)

[G. Lane]

Re Aloe Vera - it has some great healing 
properties.  There's a part of the plant that's 
toxic, but part of it is not. In general, I think 
that aloe juice is from the healing part of the 
plant, not the membrane that is or can be 
toxic.   I looked it up a few years ago and found 
a nice diagram, can't find it now though.


It's UNFORTUNATE that the web sites that label it 
as "poison" or "not poison" don't go into more detail.


For example, I use Georges Aloe vera juice 
routinely with cats, it's not poison, and has had 
some good effects on mouth problems for example, 
my Lucy had mouth inflammation and my acupuncture 
vet recommended it - and it worked great.


Also, acemanan is based on Aloe - go figure - this is from Wikipedia:
"Many of Aloe vera's beneficial properties are 
attributed to 
mucopolysaccharides 
present in the inner gel of the leaf, especially 
acemannan 
(acetylated mannans). An injectable form of 
acemannan manufactured and marketed by Carrington 
Laboratories as Acemannan Immunostimulant™ has 
been approved in the USA for treatment of 
fibrosarcoma 
(a type of 
cancer) 
in dogs and cats after clinical trials. It has 
not been approved for use by humans, and although 
it is not a drug its sale is controlled and it 
can only be obtained through a veterinary doctor."


A site called 
http://www.1st-aloe-vera.com/aloe-vera-currenthistory.htm 
- lists these significant dates and events:
"1991 - Ian R. Tizard, PhD, of Texas A&M, 
reported in the Journal of Molecular Biotherapy, 
that Aloe mannose was highly effective against 
feline leukemia and soft tissue cancer in cats and dogs.


1992 - Dr. James Duke, United States Department 
of Agriculture, approved the use of Aloe mannose 
as a treatment of soft tissue cancer in animals and feline leukemia."


Aloe is not to be written off  - it has some great healing properties.

Aloe vera is obtained from the mucilaginous

consists mainly of polysacharides and lipids. It 
should not be confused with aloes, which is 
obtained by evaporation of water from the bitter 
yellow juice that is drained from the

any anthraquinone compounds and does not therefore, exert any laxative action.

aloe extracts or aloe vera may well contain
