    Re: [RC] [RC] shoes reopened...NOT; now magnetic boots - Lisa Redmond


    Something to consider about magnets--
    
    Ever tried using these boot magnets to attach paper to metal?  Just how many
    pieces of paper will one hold before the magnetic field no longer reaches
    the metal surface?  If it only takes a few sheets of paper before the magnet
    no longer is attracted to the metal surface, then it's a safe bet it's not
    going to influence the tissues either, much less the blood.  It's a placebo
    effect, sort of like that study they just did with the arthritis surgery.
    
    Before you say, but that's paper, not tissue with all its electrolytes etc.,
    think about this logically.  Like Tamara points out, a magnet's ability to
    influence iron and other metals which can be magnetized or attracted to
    magnets is due to the ability of the ions in that substance to line up in
    the proper direction, and assumes that they can come in contact with one
    another--this is necessary for the magnetic field to be formed.  If you have
    elemental iron ions in contact with one another in the tissues or blood, you
    need to be worrying about iron toxicity and stop worrying about increasing
    blood flow.  It also assumes that the magnetic field is a bigger attraction
    to an ion than the chemical attraction of other ions within the tissue, or
    protein or lipid or carbohydrate bonds.  In addition, a magnetic field, to
    be effective, needs to pass through ions which are identical in size and
    shape and molecular weight--when you start mixing different elements, the
    strength of the magnetic field becomes compromised.
    
    Then there's the issue of a magnet being strong enough to overcome the
    hormonal controls over vasoconstriction and vasodilation that regulate blood
    flow to peripheral tissues--this is a very complex process.  And I believe
    it's a bit optimistic to think that a weak magnetic field around a fetlock
    is capable of overcoming the muscular strength of the veins and arteries.
    
    Chances are, any increase in circulation to the area of the boot is due to
    the rubbing of the boot on the skin surface as the horse moves, rather than
    the magnetic field.  In other words, massage.
    
    Lisa (who is skeptical of any and all marketing claims on magnets, miracle
    supplements, and anything else that sounds too good to be true.)
