Five people — including a 3-year-old child — were sickened by mushroom-containing gummies sold to promote brain function. They also contained unlabeled psilocybin and other harmful substances, UVA health experts say.

The gummies in question were made by Australian company Uncle Frog and were advertised as cordyceps or lion’s mane-infused. They were recalled after a slew of hospitalizations across Australia, with sufferers reporting seizure-like twitching, vomiting and hallucinations. A chemist at RMIT University says the cordyceps and lion’s mane listed on the packages don’t explain the symptoms, so “something psychoactive” is present in the gummies that were eaten.

Mushroom Gummies: A Tasty Path to Wellness

Amid the flurry of news surrounding this case, it’s worth remembering that psychedelic mushrooms are not new and that even in small doses they can be dangerous. In addition to a warning about the product, UVA health researchers have also released an analysis of five different brands of Mushroom Gummies purchased at smoke shops in Charlottesville, finding that many contain not only the fungus Amanita muscaria, but ephedrine and the natural plant kratom, which has opioid-like effects. “If you buy a mushroom gummy online, it’s going to be pretty hard for you to know what you’re getting into,” says an assistant medical director at UVA’s Blue Ridge Poison Center. “There’s no regulation in this market. They can put whatever they want in there.”
