Hi. I have a question about the weed-feed-seed protocol that David talked about in the section on gut health. He mentions garlic as a “weeding” herb. What if the person you are trying this protocol with has an adverse reaction to garlic, especially in high and raw doses (eg, stomach pain, reflux)? Would it be possible to build the numbers of healthy gut fauna without the weeding part of the protocol? Or, are there any herbs that are gentler on the stomach to use to weed out the unhealthy bacteria population?
