Those who say “what’s the harm?” in selling placebos like homeopathic drugs should take a look at this site, in particular the section on homeopathy:

People do in fact take homeopathic magic water and naturopathic slop for serious conditions, or for seemingly benign ones that turn fatal, as in the case of a 19-month-old child from Alberta whose parents had faith in supplements and watched as he grew sicker with what turned out to be bacterial meningitis:
“On March 11, however, (Ezekiel Stephan) worsened once more. He would not eat or drink. He was lethargic and his body grew stiff.”
“By March 12 (2012), he was so stiff that his back arched and the parents called their nurse and birth attendant back. She told the court she thought Ezekiel could have meningitis, and told David and Collet to take him to a doctor.”
“Instead, they gave him an electrolyte and amino-acid supplement, called Total Reload, and treated him with olive-leaf extract, garlic and methylsulfonylmethane, They also called a naturopath in Lethbridge who suggested a supplement called BLAST.”
“On March 13, on the way to Lethbridge to pick up BLAST and run errands, Ezekiel was so stiff that he couldn’t fit in his car seat. The family put him on a mattress in the back of the car. They did not take him to a doctor.”
“At 8:30 that evening, though, Ezekiel was having so much trouble breathing, David and Collet called 911 — as they were living in a remote area, they decided to drive him to the hospital, placing him, again, on the mattress in their car.”
“En route, the child stopped breathing, and Collet began to give him chest compressions and emergency breathing as they called 911; now they drove to meet the ambulance. They gave the child CPR for 10 minutes, but he was blue by the time they met the ambulance.”
“Ezekiel was eventually flown to the Alberta Children’s Hospital in Calgary, where he was declared brain dead on March 15 and removed from life support three days later.”
The parents were initially found guilty of neglect-related charges, but on appeal a judge threw out the guilty verdict. The state (crown) appealed, noting that among other things the judge rejected an expert witness’ testimony because he didn’t like the expert’s accent and command of English. That appeal was heard in June 2020; I haven’t heard of a subsequent verdict.
