BTW, a friend of mine used dong quai on her dog because she was unsuccessful at breeding her the first two times she tried. She used the dong quai until the breeding - did not give it in pregnancy at all - the dog DID successfully get pregnant but had such a horribly complicated miscarriage that the miscarried puppies had to surgically removed and the dog had to be spayed. This was given under the care of a veterinary reproduction specialist (one that I don't care for, btw). To me, that is enough to say it isn't safe =(
