Further to my earlier reply I have just come across a
reference to very recent article that may be relevant.
J Nutr 2000 Aug;130(8S Suppl):2057S-72S
Food of the gods: cure for humanity? A cultural history of
the medicinal and ritual use of chocolate.
Dillinger TL, Barriga P, Escarcega S, Jimenez M, Salazar
Lowe D, Grivetti LE.
An abstract of the article is available on Medline which
can be searched free of charge using PubMed
