Sometimes there is an inclination to distrust the US government and western medicine. We have heard about things like the medical industrial complex. So as an alternative, some people are more willing to trust natural remedies. In most cases, trusting these kinds of herbal healers would not be a problem. But, for serious diseases like AIDS, any so called cured is immoral because it spreads false hope. In certain parts of Africa, there is little or no access antiretroviral drugs. Those with AIDS have little hope, and would cling to any cure that anyone proposes.
