A reminder: How to stimulate the appetite of a medical leech

The 1996 Ig Nobel Prize for biology was awarded to Anders Barheim and Hogne Sandvik of the University of Bergen, Norway, for their tasty and tasteful report, “Effect of Ale, Garlic, and Soured Cream on the Appetite of Leeches.”

Recently, Bradley Allff, writing in Atlas Obscura, looked at the role medical leeches sometimes play in medicine in the USA. The report does not, however, look at American methods of stimulating the appetite of medical leeches that happen not to be hungry at the moment they are called to action. (Thanks to Scott Langill for bringing this to our attention.)
