Walnuts - During Medieval times, walnuts were considered
a medicine. A potion containing walnut leaves was used to treat
muscular aches and pains and walnuts were believed to soothe
the digestive system.
Later, in the 16th and 17th centuries,
herbal treatments became official medical practice under the
"Doctrine of Signatures," and various plants were prescribed
due to their resemblance to a particular body part. Hence, the
walnut, with its visual likeness to the human brain, was used
to treat head ailments, boost intellect and calm emotions.
Even today, in Asian cultures,
the walnut is considered a brain food; college students there
munch on walnuts by the handful before exams, hoping to boost
their scores. Source: walnut.org |
