I think it would depend, especially if mixing protocols. I don't mix protocols - eg I don't mix Buhner's recommended herbs with a Bryon White or with the Cowden's recommended Pinella/Burbur (which we don't use anymore). Perhaps that's just being conservative.
I do combine several Buhner's herbals together. We dropped off most of the herbals now and are only down to a few. I do combine those.
Kid#1: Extremely sick for several years, very difficult to treat, but doing great now!
Kid#2: Very sick now despite being treated for years, still very bad
Kid#3: Generally good but relapsing off/on.
Me: Adv Labs positive 2016 (suspected I passed to my kids)-not as sick as others, mostly battling fatigue and yeast issues (heart/kidney issues resolved)
Treating with herbals now.
