Bickerstaffes Honey Ltd of Liverpool (Tel. 0151 5264532, e-mail
[log in to unmask] ) supply organic cupric salts as a
non-medicinal curative substance for honeybees.
 As Dave will know, this designation is a work-around to avoid formal

thymol and formic acid. It is open to question whether or not it is
appropriate for this product.
