How Herring Roe Oil May Calm Key Immune Signals Linked to Psoriasis
This laboratory study looked at how herring roe oil affects immune and skin cells that are involved in psoriasis. Researchers used human macrophages, T-cells, keratinocytes (skin cells), and fibroblasts grown in the lab, then added herring roe oil to see how it influenced key signaling molecules.
The oil reduced the release of two inflammatory messengers, IL-23 and IL-17, from macrophages and T-cells. These molecules are central drivers of the IL-17/23 pathway that is heavily involved in psoriasis. The oil also blunted IL-17’s ability to trigger a psoriasis-related marker in skin cells and slowed the growth of keratinocytes when they were cultured together with fibroblasts.
Because this was a cell-based (in vitro) study rather than a clinical trial, the findings show biological plausibility for how herring roe oil might interact with psoriasis-related pathways, but they do not confirm effects in living people.
What this means for you
These lab results help explain, at a cellular level, why herring roe oil has been of interest for skin conditions like psoriasis, but they come from isolated cells rather than human trials, so they can’t tell us how the oil would perform in real-world use—more clinical research would be needed to confirm any practical benefit.
