Ülevaade raviturbast ja turbaravist (Review of therapeutic peat and peat therapy)
Key Findings
- Comprehensive Estonian-language review of therapeutic peat covering composition, mechanisms, applications, and clinical evidence
- Anti-inflammatory effect mediated by sulfoglycolipids lowering IL-1, arachidonic acid, LTB4, PGE-2, and thromboxane
- Peat bioactive substances absorbed through hair follicles and apocrine glands via diffusion
- Peat bath vasodilation exceeds plain water bath — effect persists for hours after treatment
- Humic acid estrogenic activity 5000× estradiol standard in Allen-Doisy test (mice)
- TPP (Tolpa Peat Preparation) registered as immunomodulator drug in Poland — stimulates interferon-α, interferon-γ, TNF-α
- Humic acids are antiviral — block virus attachment to cell surface by occupying positively charged glycoprotein regions
- HA concentration-dependent: 10–80 μg/ml increases TNF-α 3× (pro-inflammatory), >100 μg/ml decreases TNF-α 10× (anti-inflammatory)
- Peat should not be heated above 60°C — above this, HMA concentration increases 2.5× causing receptor desensitization
- Highest-yielding Estonian bog peat studied: 59% humic substances, 33% of which are HMA, 7.3% lipids
- Peat therapy indications: acne, rheumatic pain, psoriasis, osteoarthritis, fibromyalgia, stress, skin conditions
- Contraindications for peat bath: high fever, open wounds, heart failure, high blood pressure, diabetes, pregnancy
Comprehensive review by Monika Übner (Health Resort Laboratory, University of Tartu Pärnu College) covering the full scope of therapeutic peat science. Written in Estonian, this review synthesizes European peat therapy literature with Estonian peatland research.
Key Topics Covered
- Peat composition — Humic substances (HA, HMA, FA), lipids, trace elements; quality criteria (H6+ humification, >20% HS, <12% ash)
- Skin effects — Transdermal permeation of bioactives; seborrheic dermatitis treatment (82 patients); skin moisture and lipid improvements
- Humic substances — Detailed biochemistry; FA/HMA agonist activity on α2-adrenergic and D2 dopamine receptors; 4–6 hour duration
- Anti-inflammatory mechanisms — Sulfoglycolipids, cytokine modulation, dose-dependent TNF-α response
- TPP (Tolpa Peat Preparation) — Polish immunomodulator drug; interferon stimulation; antitoxic, antimutagenic properties
- Clinical applications — Peat baths, wraps, sauna protocols; indications and contraindications lists
- Estonian peat — highest-quality source identified among deposits studied; ecological purity; heavy metal safety
Significance for Knowledge Graph
This review serves as a secondary source connecting many primary studies already in the graph. Its value lies in the comprehensive contraindications list, the TPP immunomodulator data, and the Estonian-specific peat characterization. The dose-dependent TNF-α finding (Junek et al. 2009) is particularly important for understanding humic acid’s bimodal immune effect.

Review citing Pedrinazzi et al. 2009: 82 patients, peat + mineral water mask effective for facial seborrheic dermatitis
Review: peat applications for hand dermatitis and psoriasis help relieve itching, reduce inflammation, pustules recede faster
Review confirms FA antiallergic effect — inhibits β-hexosaminidase and histamine release, decreases intracellular calcium
HA dose-dependent: 10–80 μg/ml increases TNF-α 3× (pro-inflammatory), >100 μg/ml decreases TNF-α 10× (anti-inflammatory) — Junek et al. 2009 via review
HA blocks virus replication by occupying positively charged glycoprotein regions needed for cell attachment; most HA showed antibacterial activity in vitro (Ansorg, Rochus 1978)
HMA fraction has agonist/partial agonist activity on α2-adrenergic and D2 dopamine receptors (Beer et al. 2000a/b, 2002)
