     Graham, do you really suggest that people do this? The Merck Index 
     says about DMSO: "Skin contact results in primary irritation with 
     redness, itching and sometimes scaling. Urticarial wheals are not 
     uncommon."
     
     Try this instead: take a slice of lemon, pop it into a chilled bottle 
     of Sol or Corona, then invert twice and drink.
