Source/Predictability of a herx?

Trying to understand more how you differentiate between a herx and normal flare up symptoms. Yes I've seen the website with the two but wanted to dig deeper. For example some folks will take an abx, herb, hot bath or some other "trigger" mechanism and they'll feel symptoms and say "I herxed from it". Those seem cut and dry but I have to imagine there are folks like me who get symptoms that have varying intensity/duration with no discernible patterns to them.

What is happening in these situations? Is the immune system kicking in and killing bugs and causing a toxic spike? Are there generations of bugs that have their own lifecycles and dying off and causing toxic spike? Are antibiotics and/or herbs you take kicking in at various times during their existence in your system and killing bugs off? Maybe its all possibly true but curious from the board what has been your experiences. More understanding here can help folks better manage their "bad times" and work around them if they have things they need to do. Thanks.

I think it's easiest to tell what's what when you're doing treatments that you pulse. There is generally an identifiable herx pattern that plays out over several days very much like clockwork.

For me, when I was doing essential oils I'd use them and then herx in a predictable way over the next 5 days. The 4th day afterwards I'd always be herxing the worst. The 5th day things would subside and by the 6th I'd be fine again.

With Rife the pattern is exactly the same, the 4th day after a Rife session is the almost always the worst day and I'm usually back to normal by the 6th.

I believe the pattern depends a lot on your body's immune system and innate detox capabilities. Once you learn the pattern you can use it to judge the effectiveness of the treatment and also plan your activities.
