A Herxheimer reaction, commonly known as "die-off," typically lasts between 2 to 7 days. The duration and intensity depend on your body’s toxic load and the efficiency of your drainage pathways. If symptoms like fatigue, headaches, or skin breakouts persist longer, it may indicate a bottleneck in your detoxification system.

Experiencing a "Herx" is a sign that your parasite cleanse is working, as dying organisms release endotoxins into the bloodstream. However, to shorten this window, it is vital to keep your drainage pathways (liver, kidneys, colon) open. Increasing your intake of binders, such as activated charcoal or bentonite clay, can help mop up these toxins, significantly reducing the severity and length of the reaction.
