Leprosy

Among Medieval diseases Leprosy was one of the most threatening.

Leprosy had a direct impact on a person’s skin, eyes, nerves and breathing.

Medieval people suffering from leprosy could lose their fingers, toes and even the tips of their noses.

There were separate houses called “leproseries” for the sick as it was thought that leprosy was a contagious disease at that time.

People with leprosy were separated from their families and had to live their lives in seclusion.

Lepers had special dresses for public appearances in order to warn people that they were coming – they also rattled their clappers or bells.

It was the church’s responsibility to take care of such people.

Leprosy had a direct impact on a person’s skin, eyes, nerves and breathing.


The Black Death

Among medieval diseases the Black Death or the black plague was the deadliest.

From around 1346 – 1353 AD around 75 to 200 million people died of this disease.

It was estimated that this disease had killed 1 in 4 people.

It is believed that the Black Death came to Europe on 12 trading ships that sailed from central Asia.

These ships docked on the Italian seaports had sick and dead people aboard.

Locals eventually succeeded in sending the ships away, but it was already too late as many people had already caught the disease.

The infected people, then unwillingly spread the disease as they traveled from town to town.

The black plagues consisted of three types of plagues

  • Bubonic.
  • Septicemic.
  • Pneumonia.

Some people thought that these plagues were sent from God in order to punish them for their sins. These people arranged religious processions for forgiveness.

Worst Medieval Diseases

The worst medieval diseases were the leprosy and the black death.

Although with leprosy people suffered a lot and it caused organ withering and wound formation – but it still was nowhere near as bad as the ‘Black Death’ that took lives of hundreds of millions.

Leprosy spread through the nasal secretions of patients, whereas the black plague was an endemic that spread like wild fire.

Bubonic Plague

The Bubonic plague was the main plague of the three plagues that caused the Black Death.

It was caused by the “Yersinia pestis” bacterium that transferred to a human through an infected flea bite.

When the bacteria entered into a person’s lymphatic system, it developed buboes – painful bumps, under the armpits, groin or on the neck. Fevers and headaches were also present.

The only way a person could survive was if the bumps broke open, spilling out the poisonous bacteria.

If the bump did not open the people died within three days of first bump!

Cures for Medieval Diseases

Medieval diseases were mainly cured by balancing the four humors – mucus, blood, black bile and yellow bile.

There was no major development in the field of medicine during medieval times hence most diseases were cured by herbs and plants.

The ancient doctrine of analogy was applied and it was thought that to treat heart diseases heart shaped leaves were good, for kidney diseases kidney shaped leaves were used.

In order to treat eye diseases, flowers resembling the eye’s shape were used.

Leprosy was mainly treated by sending the patients to separate houses and keeping them away from healthy people.

For treatment of the plague a herb called “plague root” was used.

Plague root’s leaves were wrapped around the infected areas and the roots were boiled in wine and given to patients for eating.
