There is no evidence that the vitamin C content of lemon (about 80 milligrams per 100 grams)
would have any beneficial effect. There are many other components in lemons, and some of these
could potentially have a medicinal effect.
On the question of unique healing properties of honey, it is true that honey is simply another form
of the simple sugars (fructose, glucose and sucrose). However, from time to time honey acquires
biologically active substances from the flowers on which the bees feed. Occasionally there are
outbreaks of illness due to the presence of harmful substances in honey that have been obtained
from flowers. It is quite conceivable that honey may sometimes contain medicinally useful
compounds collected by bees from some flowers in the same way as those that cause illness, but
so far there has been no scientific evidence to support this.
