    "concept_summary": "A collection of studies reports that aqueous extracts from several medicinal herbs (e.g., Spirulina platensis, Calcium-Spirulan, Nigella sativa, Scutellaria baicalensis) exhibit antiviral activity against HIV-1 in vitro and, in isolated case reports, in vivo. The extracts are claimed to block viral entry or replication, leading to reduced viral load and, in some anecdotal cases, sustained seroreversion.",
    "detailed_description": "The article surveys peer-reviewed papers, patents, and case studies. Key findings include: (1) Spirulina platensis aqueous extract reduces HIV-1 production by ~50 % at 0.3-1.2 ug ml^-^1 (EC_5_0) and shows a therapeutic index of 200-6000; (2) a purified polysaccharide-calcium polymer (Calcium-Spirulan) inhibits HIV-1 and other viruses by preventing viral attachment to cell membranes; (3) Scutellaria baicalensis contains baicalin/baicalein which suppress HIV infectivity; (4) Black seed (Nigella sativa) extract was reported in a single case study to achieve complete seroreversion. Patents describe extraction methods for baicalin and related flavonoids, but no large-scale clinical data are presented.",
