Because many homeopathic products are nothing more than water and fillers, they’ve often been disregarded as harmless placebos. But there have been a growing number of cases in recent years of homeopathic products that have been improperly diluted or diluted with contaminated water containing disease-causing microbes. Many of the products were intended for children and infants.
For instance, in 2016, the FDA reported that homeopathic teething gels and tablets had been linked to the deaths of 10 babies. There were reports of more than 400 other infants being sickened by the products, some suffering seizures. The products were supposed to have highly diluted amounts of belladonna, aka deadly nightshade, but FDA testing revealed elevated and wildly variable amounts of the toxic substance.
