On NO account treat your dog
with any of the herbs I mentioned
in that other post, without fully checking
with a vet first, and that would have to be a vet who knows about herbal treatment of dogs.
As Ghilly said, many products and remedies which are fine for Humans, can be poisonous for dogs, or indeed any other animal, as their whole systems are different to ours. That includes Herbal remedies. Some are fine, some are not. Only a qualified Herbal Vet would know.
