Science
Mechanism of Action
Hypochoeris Radicata Flower Extract demonstrates its anti-inflammatory effects by inhibiting the generation of nitric oxide (NO) and by suppressing the phosphorylation of mitogen-activated protein kinases (MAPKs) such as p38, ERK, and JNK. This mechanism leads to a reduction in pro-inflammatory molecules (iNOS, PGE2, COX-2) and cytokines (TNF-α, IL-1ß, IL-6). The extract also functions as a natural antioxidant, providing protection against oxidative stress through its rich content of compounds including luteolins, quercetin, naringenin, catechin, other phenolic compounds, and various flavonoids.

Key findings
- 01 In *in vitro* studies on LPS-stimulated RAW 264.7 macrophages, ethanol extracts at concentrations up to 500 ug/mL demonstrated effective inhibition of nitric oxide (NO) generation without any observed cellular toxicity.
- 02 An ethyl acetate fraction (HRF-EA) of the flower extract, at concentrations ranging from 12.5 to 50 µg/mL, significantly inhibited the production of a spectrum of pro-inflammatory molecules (NO, iNOS, PGE2, COX-2) and cytokines (TNF-α, IL-1ß, IL-6). This anti-inflammatory action was correlated with a concentration-dependent suppression of p38, ERK, and JNK MAPK phosphorylation.

Safety
Safety Profile
Hypochoeris radicata extracts have shown no toxic effects on cells in *in vitro* studies. While the plant generally exhibits low severity poison characteristics, there is a risk of allergic reactions in individuals sensitive to plants from the Asteraceae family. This ingredient has not been reviewed by the CIR and is not on its current or draft priority lists.
