When a doctor gives you a natural or prescription antibiotic, the dead bacteria break apart, spilling their toxic (endotoxins) microscopic guts into your tissues causing a worsening of your symptoms and often new symptoms. This worsening of your symptoms is called a Jarish-Herxheimer reaction, or “herx.”
A herx is not just any worsening experienced for any reason while you are being treated for Lyme disease. People often say things such as, “I took a detox product and herxed badly” or “I took vitamin C and herxed.” I have even heard people say they ate cheese, or used a laptop computer and herxed. None of these things will cause a herx. Simply having a worsening of your symptoms is NOT a herx reaction.
