This was supposed to be homeopathic (the label says so), but contained dangerous levels of ingredient, even after the manufacturers were warned.
If there was actual quality control, that would be the case. Actual "homoeopathic" products, OTOH, are, in fact, often not what the purported process would produce, and have been known to be dangerous.
