Only poisonous for cold-blooded animals like insects and fish. Is that the same as pyrethrum, related, different? What is it? Pyrethrum was originally gotten from a mum. A few years back a gent on the FML lost something like 7 ferrets to that compound when too much was used by a housemate. The _PDR for Herbal Medicines_ tells how to treat for that type of poisoning using gastic lavage, charcoal, and special kidney and respiratory procedures. [Posted in FML issue 3359]
