Science

This extract is believed to exhibit anti-inflammatory effects by modulating the expression of key cellular adhesion molecules and chemokines such as VCAM-1, ICAM-1, IP-10, I-TAC, MIG, and M-CSF. It also demonstrates antiproliferative activity and influences tissue remodeling pathways through the inhibition of collagen-I, collagen-III, PAI-1, TIMP-1, and TIMP-2. Broader Thuja extracts are recognized for antioxidant, anti-inflammatory, and antiseptic properties, which collectively help protect the skin from oxidative stress, reduce inflammation, soothe irritation, and promote overall skin regeneration.

Key findings

  1. 01 An in vitro study demonstrated that 0.011% Thuja plicata essential oil significantly inhibited the expression of various inflammatory biomarkers (VCAM-1, ICAM-1, IP-10, I-TAC, MIG, M-CSF) and key tissue remodeling proteins (collagen-I, collagen-III, PAI-1, TIMP-1, TIMP-2) in a pre-inflamed human dermal fibroblast culture model. This suggests potential anti-inflammatory and tissue remodeling capabilities, though these findings are specifically linked to the essential oil, not directly the stem extract.

Stability

Optimal pH range for stability is not specifically documented. As a general plant extract, it may contain both oil-soluble components (like those found in essential oils from Thuja plicata leaves) and water-soluble components (such as polysaccharides).


Safety

CIR Status
Not reviewed
Sensitization risk Moderate

No specific safety assessments from CIR, SCCS, or FDA have been found for THUJA PLICATA STEM EXTRACT. Thuja plicata essential oil contains thujone, a compound considered toxic in large amounts, which is a consideration for extracts. General plant extracts have the potential to cause acute toxicity, skin/eye irritation, or sensitization with topical application.
