-- " Is the Iodine Skin Patch Test valid? " --

In October 2003 I asked Ray Peat PhD about this due

to his many years of hormone related researches where

iodine was a key factor in his focus.

Peat replied:

" The people I have seen administering the iodine

skin test use the brown tincture, and time the

disappearance in seconds and minutes.

They think they are measuring a sort of tissue-hunger

for iodine, but what they are really measuring is the

reductive capacity of the skin surface, most of which is

probably ascorbic acid, that simply bleaches the iodine

into iodide.

I always have tincture of iodine to use on dirty injuries,

and I agree that the concentrated iodide solutions

sometimes do remarkable things, ... " (Oct. 21, 2003)

I understood him to mean 'Tincture of Iodine' but I

admit his phrasing was open to other interpretations.

So I emailed him for clarification:

Pat:

" Back in Oct 2003 you wrote re the iodine skin 'test'.

You stated:

'The people I have seen administering the iodine

skin test use the brown tincture...'

Were you referring the iodine product commonly

found in drug stores under the name/s:

'Iodine Tincture' and/or 'Tincture of Iodine'? "

Peat replied (Jan 22, 2006):

" Yes, the standard drugstore brown tincture. "

[Pat:

So we are all talking about the same thing:

" Iodine Tincture " and/or " Tincture of Iodine "

A 'tincture' in pharmacology is a medicine consisting

of an extract in an alcohol solution.

'Iodine Tincture' and/or 'Tincture of Iodine' refers to

" A tincture consisting of a solution of iodine in ethyl alcohol. " ]

Pat (a further question to Peat):

Any reason for the reference to " brown " in

discussing iodine tincture?

Is " brown " significant in some way?

Are the other color iodines where the color is relevant?

Peat (Jan. 27, 2006):

" The brown just indicates the presence of molecular iodine;

the iodides are clear. "
