Curcumin for COVID-19
15th treatment shown to reduce risk in February 2021, now with p = 0.0000000096 from 27 studies.

Small RCT with 40 low risk patients in Iran, 20 treated with nano-curcumin, showing no significant difference in outcomes with treatment. Authors note that treatment can improve peripheral blood inflammatory indices and modulate immune response by decreasing Th1 and Th17 responses, increasing T regulatory responses, further reducing IL-17 and IFN-γ, and increasing suppressive cytokines TGF-β and IL-4.
This is the 6th of 21 COVID-19 RCTs for curcumin, which collectively show efficacy with p=0.0000022.
This is the 9th of 27 COVID-19 controlled studies for curcumin, which collectively show efficacy with p=0.0000000096 (1 in 104 million).
relative improvement in SpO2, 45.7% worse, RR 1.46, p = 0.90, treatment 20, control 20.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
