The only thing mentioned by Burroughs is Mint tea.
"The rest are just herbals and I don't see where they would hurt."
Why bother to give a blanket advice such as this when the actual truth of the matter is that it's just a "blanket guess" since you have absolutely no idea what herbs or teas a person can take that might stimulate particular bodily functions that would work at odds with the simple workings of the MC.
