Mechanism of Action

Wound Healing Promotion

Also: wound healing, tissue repair, regeneration

Wound healing promotion by peat involves multiple synergistic mechanisms: antimicrobial protection of the wound bed, anti-inflammatory reduction of excessive wound inflammation, mineral delivery (zinc, iron) essential for tissue repair, and potential direct stimulation of fibroblast and keratinocyte activity.

Historical Basis

Sphagnum moss has been used as wound dressing material for centuries, with large-scale military use during World War I. The combination of high absorbency, natural antimicrobial activity, and acidic pH created favorable conditions for wound healing. Modern research is now investigating the specific molecular mechanisms behind these traditional observations.

Evidence Quality

Historical and ethnobotanical evidence is strong and well-documented. Modern in-vitro evidence showing humic substance effects on cell proliferation and migration is preliminary. Clinical trials specifically testing peat preparations for wound healing are limited.

How It Works

Targets Fibroblasts, keratinocytes, extracellular matrix
Pathway Stimulation of cell proliferation, collagen synthesis, antimicrobial protection of wound bed

Active Substances

Compounds that exhibit this mechanism

Fulvic Acids

In peat: 5–20% of dry mass, higher ratio in sphagnum peat
→

Iron

In peat: 0.1–2% of dry mass, highly variable by source
→

Polysaccharides

In peat: 5–15% of dry mass, decreasing with humification
→

Sphagnol

In peat: Trace — primarily in fresh or lightly decomposed sphagnum peat
→

Zinc

In peat: 10–200 ppm, variable by source
→
