Legal/illegal varies from Country to Country; I believe this is an International list, so subscribers, please treat scattergun comments on 'legality' with care. In the UK the question of what is legal and what is illegal is very hard to determine. There are some very specific Regulations that outlaw everything but Licensed medicines. However the Government Agency that drew up these Regulations has subsequently given advice that other substances - 'non-medicinal curative substances'- can be used in the hive provided that if they are transmitted to animal product they would not be harmful to human health. Sadly there is no definitive list of these substances, so it is very much a case of 'user beware'. In European Regulations defining maximum residue limits of veterinary medicinal products in foodstuffs of animal origin, menthol and thymol are not subject to maximum residue limits, and camphor, eucalyptol and formic acid are listed as 'generally recognised as safe' and are also free of maximum residue limits. Thus the substances mentioned by Bill Truesdell are apparently not illegal in the European Union, nor is formic acid subject to any licensing requirement, Regards -- Mike Rowbottom HARROGATE UK
