This quote is often attributed to Paracelsus, a 16th century Swiss-German physician and alchemist who is credited with setting the foundation of modern-day pharmacology and toxicology. The quote is praising the power of plants, herbs, and stones and suggests that their true qualities are not fully understood or appreciated.
