You used the right word indeed... the word "believe"... I do not think
this to be the right place to speak about "beliefs"; if you have some
clinical studies demonstrating the potential risk for human health for
such "contamination" your are speaking about, I'll be glad to read it.

How you judge if something is a "strange foreign chemical" or a
"familiar indigenous chemical"? Accordingly to how its name sounds? To
the opinion of an healer? To what someone wrote in his blog?

I am not aware of any studies about conductivity of pure aloe and
actually I do not see any reason to use exactly that... apart from the
fact that it is quite trendy to use it to do everything in various
pseudo-scientific communities.

Despite of this, some kind of electrodes are designed to be used with
saline solution (instead of conductive gels), as the ones used for the
Emotiv EPOC (http://emotiv.wikia.com/wiki/Emotiv_EPOC). You may try to
build your own electrodes following this approach.
Anyhow, although I do not own this device, I have heard that
electrodes do not last a lot, since as you correctly pointed out,
saline solutions tend to corrode some of the electrode components.

Just a warning: keep in mind that what they sell as ordinary salt is
actually more than 90% "Sodium Chloride", which is an ionic compound
with the chemical formula NaCl, representing equal proportions of
sodium and chlorine... so I do not know if it may be consider as a
"strange foreign chemical" or not... moreover you commonly dissolve it
in another chemical commonly known as "Dihydrogen Monoxide" which may
be considered poisonous as well: http://www.dhmo.org/

Probably most of the people in this list do not... so I beg their
pardon... if you want to keep speaking about this we could go on with
private mails... anyhow in my opinion, you are just tying up to a
slightly more unconventional matrix. ;)


Bye,

Enrico
