The world’s deadliest mushroom, the death cap, may finally have an antidote thanks to Chinese and Australian scientists
- Death caps cause 90 per cent of mushroom-related fatalities worldwide
- Study finds that a medical dye can reduce the toxicity of the lethal fungus
Chinese and Australian scientists say they have found a potential antidote for the toxin in the world’s most poisonous mushroom – the death cap.
In China, almost 800 deaths and 40,000 illnesses from consuming death caps were reported in the decade to 2020. The mushroom – Amanita phalloides – is commonly found in the southern provinces of Yunnan, Sichuan and Guangdong.

Death caps produce a toxin known as α-amanitin that causes irreversible liver or kidney damage. But scientists have long been unable to understand exactly how the toxin poisons humans and there is no antidote available.
In the study, the team found that a medical dye could reduce the toxicity of the death cap toxin in human cells and mice and increase their probability of survival after being exposed to the toxin. The substance – called indocyanine green – has for decades been used in medical tests to measure liver function and cardiac output.
