The thing you here the most from ill people is hope they can't take herbs. Thats why I tell them to use the orange juice fasting correctly and naturally the answer comes back that I can't fast, I can't do this, I can't do that, etc.
BUG chasing is a old medical art of scamming people out of their $$$$$. Bugs are only there because of wrong diet. Those refusing to change their diet seek drugs or herbs as aids to their diet problems.
I suggest the person start from scratch as explained over and over a thousand times, first distilled water, then no dental metals, cleanse their bowels, cleanse their kidneys, do a liver flush, then fast utnil cured, etc.
To say take this and the big of choice will no longer bug you????? NOT, then the person will just bad mouth the herb and say it was a rip off.
The above is just general answers about the subject of taking a herb for 1 thing that ails you. I like you would use oregano oil and Olive Leaf daily as the best way to maintain the balance of bugs eating the body. But the cure will be the elimination of the causes and my guess she has many causes that she probably will not want to give up.
