There are words you don't use in medicine today, such as "cure." But a remarkable case study in an HIV positive patient treated with black seed extract resulted in a sustained remission, indicating a safe, accessible and affordable alternative to highly toxic antiretroviral HIV drugs may already exist.
Nigella Sativa, also known as 'black seed,' has been studied for a wide rage of health benefits, but not until recently was it discovered to hold promise as a curative agent against potentially lethal viral infections, including Hepatitis C  and now HIV.
A remarkable case study published in August of this year in the African Journal of Traditional, Complementary, and Alternative Medicine described an HIV patient who after undergoing treatment with a black seed extract experienced a complete recovery, with no detectable HIV virus or antibodies against HIV in their blood serum, both during and long after the therapy ended. 
This was a remarkable and unexpected observation, described by the researchers as follows:
"Nigella sativa had been documented to possess many therapeutic functions in medicine but the least expected is sero-reversion in HIV infection which is very rare despite extensive therapy with highly active anti-retroviral therapy (HAART)."
Despite its commonplace use as the standard of care for HIV treatment globally, anti-retroviral therapy remains highly controversial, in part because the adverse health effects of the drug class may outstrip those associated with the HIV infection itself.
