Detailed Outcomes

Diuretic Effect

In rodent models, Boerhaavia diffusa extracts consistently demonstrate diuretic activity with increased urine output. This aligns with its long traditional Ayurvedic use for edema and ascites. No human clinical trials have been conducted to validate this effect.

moderate↑Improves

Liver Protection

Animal studies show hepatoprotective effects of Boerhaavia diffusa extracts, with reductions in liver enzyme markers of damage. Traditional use for jaundice supports this application. No human data available.

Anti-Proliferative Effects (Cancer Cell Lines)

Isolated boeravinone compounds from Boerhaavia diffusa show anti-proliferative activity against cancer cell lines in vitro. This is very preliminary evidence — in vitro effects frequently fail to translate to clinical benefit in humans.

Immunosuppression

In animal and in vitro studies, Boerhaavia diffusa suppresses T-cell proliferation and immune cell activity. This immunosuppressive effect could theoretically benefit autoimmune conditions but poses risk during infections. No human trials exist.

Thunder god vine

1 shared condition · 7 outcomes

Thunder god vine is a Traditional Chinese Medicine herb with PROVEN efficacy for rheumatoid arthritis but DANGEROUS toxicity. Has a VERY LOW therapeutic index (narrow margin between effective and toxic doses). Can cause severe adverse effects including infertility, immunosuppression, and death. NOT RECOMMENDED for self-supplementation. Used only under strict medical supervision in some countries. The active compounds (triptolide, celastrol) are potent but toxic.

Idebenone

1 shared condition · 12 outcomes

Idebenone is a synthetic CoQ10 analog with better bioavailability and unique redox properties. FDA-approved for Leber's hereditary optic neuropathy (LHON) and used off-label for Friedreich's ataxia and other mitochondrial diseases. Unlike CoQ10, can accept electrons from complex I (bypassing mitochondrial blocks). Used in cosmetics for skin aging. Has nootropic interest but cognitive benefits in healthy people unproven. More potent antioxidant than CoQ10 in some assays.
