I understand that this topic might cause some discomfort or leave a "bad taste" among Pu-Erh lovers (like myself) but I really like to share some ideas and information here that might lead to some insight and/or clarification.
After lengthy discussions on rfdt and elsewhere on all sorts of possible species of Pu-Erh "kin", namely different strains of fungi, especially those of the Aspergillus family I´m a bit concerned as to the general possibilities of Pu-Erh teas containing aflatoxins, one of the strongest carcinogens known to man.
