A Large Number of Mushrooms are Poisonous

Amanita Phalloides - The 'Death Cap' Mushroom is Responsible for Most Cases of Poisoning

The appropriately named Death Cap mushroom is the cause of 90% of death by mushroom, both in the US and Europe. Just eating one to three mushrooms can cause symptoms, and in 20-30% of cases, it is fatal (in children under 10, the mortality rate is 50%).

Amanita phalloides has a metallic green-brown cap with white gills under the cap. The stem is white and there is a swelling at the base of the stem. However, there is also a completely white strain, which can resemble other non-toxic mushrooms.

Amanita mushrooms contain amatoxins, which stop DNA from replicating, preventing production of new body cells. This causes severe problems, as the gut, liver, kidneys and immune system rely on constant manufacture of new cells. There are three stages of poisoning:

Stage 1: Pain, vomiting and diarrhoea start as soon as 6 hours after eating Death Caps. This leads to dehydration and a fall in blood pressure.

Stage 2: For 1-2 days, the patient appears to have recovered. However, the kidneys and liver are being damaged, and the 'recovery' is an illusion.

Stage 3: The liver and kidneys fail, leading to death within 2-3 weeks. The patient may slowly recover if they only ate a small dose of Death Cap.

Poisoning by Death Cap mushrooms can be confirmed by analysis of the blood, urine or stomach contents. It can only be treated by attempts to remove the toxin from the body, such as by stomach pumping, inducing vomiting, ingestion of activated charcoal to absorb toxins, or blood dialysis. There is no antidote. Rapid medical attention is therefore essential for anyone suspecting that they have been poisoned by Amanita mushrooms.

Although it Looks Innocent Enough, the Amanita Mushroom is Poisonous

Was Roman Emperor Claudius Murdered with Mushrooms?

Tiberius Claudius Caesar Augustus Germanicus, or Claudius I, was born in A.D. 10 and ruled the Roman Empire from A.D. 41 until his death in A.D. 54. Although his reign was successful and he oversaw the conquest of Britain, he was consistently seen as vulnerable and had to consolidate his position. Many senators died during Claudius' reign.

Some historians say that Claudius died after a single dose of poisonous mushrooms, while others say that he was poisoned, recovered and then was poisoned again.

Although accounts vary, historians agree that he was murdered and that his wife Agrippina is the most likely culprit. Agrippina was Claudius' fourth wife, and was probably chosen for political reasons. She was Claudius' niece and one of the last descendants of the legendary Augustus. She also had an adult son (Nero), who would provide an heir if needed, as Claudius' only son Brittanicus was still a boy. Their marriage would also end feuding between the Claudian and Julian families. Nero and Brittanicus were made joint heirs.

In the months before Claudius' death, his relationship with Agrippina deteriorated, and Claudius spoke of restoring Brittanicus to be the sole heir. Agrippina had motive to kill Claudius to protect Nero's inheritance. Although some think that Claudius died of natural causes, the consistent reports of murder and the clear motive for Agrippina make it likely that he was indeed murdered.
