#DerApotheker is an anonymous German pharmacist with ten years of experience. Day after day, he has to repeat to pharmacy visitors the same recommendations and warnings about drugs with unproven effectiveness. Since 2018, he has been running a blog where he not only shares useful information about medications, but also talks about homeopathy and pseudo-medicine, based on evidence-based medicine. Many people often do not know the most important facts about tablets, sprays and drops that they take on a regular basis. Due to ignorance, they put themselves in danger. This book explains how drugstore bestsellers work, what to consider when taking them, and when you're throwing your money away.
