Research on HIV/AIDS
“The grass is greener where you water it.”
— Neil Barringham
Doctors and nurses working in the field with ARHF often see clear improvements in patients treated with PC Remedies. This firsthand experience gives them confidence in using these natural, information-based remedies. Still, to expand access and promote wider acceptance, ARHF places strong focus on collecting data and supporting research—despite the challenge of limited research infrastructure in rural areas where many of our teams work.
Since PC1 for HIV/AIDS was first introduced in 2002, positive clinical outcomes—such as higher CD4 counts and restored energy—have been reported across multiple countries, including Ethiopia, Malawi, Nigeria, Kenya, and Uganda. [1-5]

Treatment Impact: Immune Strength and Virus Control
Kenya Comparative Study (2017–2018)
Over six months, all groups showed improvements—but the PC1-only group had the most significant gains in appetite, weight, energy, CD4 counts, and reduced viral load. The combined ARVs + PC1 group showed the second-best results, while the ARV-only group showed the least progress. Bellow are detailed results in percents.
CD4 Increase
CD4 cells are a type of white blood cell that helps protect the body from infections. HIV attacks these cells, so a higher CD4 count means a stronger immune system. Tracking CD4 levels helps monitor how well treatments are working.
Viral Load Decrease
Viral load refers to the amount of HIV in a person’s blood. A lower viral load means the virus is under control, reducing symptoms and the risk of transmission. Effective treatments aim to decrease viral load to undetectable levels.
