Experiences from Ghana indicate these are helpful formulations. If you are looking at something to help boost your system either as complimentary or stand alone, please try any of these or all in combination. From what I have seen, I have presented the formulations in order of efficacy, not as a cure though. And to help others, would any of you who have used any of these share their experience? The skeptics are also free to comment and share their opinion. Please note, I have no affiliation/association/relationship with sellers or manufacturers of any of these.
