The Herbal Cures of Hildegard von Bingen – was she right?
Medievalists.net
Among the many attributes of the Hildegard von Bingen – theologian, composer, abbess and mystic – was that she was a medical writer. Two of her works detail health problems and offers various treatments. A scientific study suggests that her herbal remedies were far more correct than what could be explained by mere chance.
The scientists wanted to know the likelihood the abbess was correct in her claims, and was this level of accuracy just purely from chance? Here is how they explained their analysis:
Our statistical approach
is based on the model of the game Battleship where a two-dimensional
grid (similar to an Excel spreadsheet) is formed by all the claims known
to the author on one axis and the herbs (those still used today) on the
other axis. Modern herbal indications (medical uses) are represented as
‘ships’ which the medieval author tries to hit by randomly tossing a
‘missile’ into the grid. The hypergeometric distribution gives the
probability that x ‘correct’ indications (‘hits’) could be drawn from
the set of N herb/claim combinations with n ‘shots’, and the number of
‘ships’ (today’s herb/claim attributions) is M.
They focused their study on 85 plants that are being used today for
medical purposes. It found that there were 212 health claims by
Hildegard from this group, and 30 of them would be correct according to
contemporary standards. If she had been making the claims up randomly,
only between 6 and 7 of her cures would have accurate.The study finds the probability of this happening just by chance is 1 in 10,000,000. They conclude:
The hypothesis that
Hildegard could have achieved her ‘correct’ claims by chance is to be
clearly rejected on the basis of the highly significant level of our new
statistical procedure. The finding from this approach that medieval
medical claims are significantly correlated with modern herbal
indications supports the importance of traditional medicinal systems as
an empirical source.
They add that European researchers should also be more open to the
possibility that herbs might be responsible for a larger variety of
remedies – typically these plants are now only associated with one or a
small number of medical treatments.You can read the article “Are the Correct Herbal Claims by Hildegard von Bingen Only Lucky Strikes?

An excerpt from Hildegard von Bingen’s Physica: The Complete English Translation of her Classic Work on Health and Healing, by Priscilla Throop (1998):
Rose is
cold, and this coldness contains moderation which is useful. In the
morning, or at daybreak, pluck a rose petal and place it on your eyes.
It draws out the humor and makes them clear. One with small ulcers on
his body should place rose petals over them. This pulls the mucus from
them. One who is inclined to wrath should take rose and less sage
and pulverize them. The sage lessens the wrath, and the rose makes him
happy. Rose, and half as much sage, may be cooked with fresh, melted
lard, in water, and an ointment made from this. The place where a person
is troubled by a cramp or paralysis should be rubbed with it, and he
will be better. Rose is also good to add to potions, unguents, and all
medications. If even a little rose is added, they are so much better,
because of the good virtues of the rose.
