Honey should not be given to children under the age of one, as it may contain spores of botulism bacilli in amounts that pose a threat to the health and life of such young children. Eating honey may also be inadvisable for people suffering from reflux. There was a recent promotional campaign for manuka honey (honey extracted from the flowers of the manuka plant, which grows in Australia and New Zealand), which was said to be good for digestive diseases and other conditions, but no scientific evidence of this was found. The New Zealand government has banned producers of these honey from citing the therapeutic effects of manuka honey on their labels.
