The Claim

Gingerdione, shogaol, capsaicin, and related pungent compounds inhibit 5-lipoxygenase activity in isolated human neutrophils, with gingerdione exhibiting the strongest inhibitory effect (IC50 = 15 μM), and suppress prostaglandin E2 formation (IC50 = 18 μM), demonstrating dual inhibition of arachidonic acid metabolic pathways in vitro.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Gingerdione, shogaol, and capsaicin reduce the activity of the enzyme 5-lipoxygenase and lower the production of prostaglandin E2 in human neutrophils under laboratory conditions, indicating they block two related pathways in arachidonic acid metabolism.

See the scientific wording

Gingerdione, shogaol, capsaicin, and related pungent compounds inhibit 5-lipoxygenase activity in isolated human neutrophils, with gingerdione showing the strongest effect (IC50 = 15 μM), and also suppress prostaglandin E2 formation (IC50 = 18 μM), indicating dual inhibition of arachidonic acid metabolic pathways in vitro.

Why this might work

Spicy compounds from ginger and chili peppers enter white blood cells and block two key enzymes that turn fat molecules into inflammatory signals, stopping both leukotriene and prostaglandin production at the same time.
