Key Findings
- Water-soluble fulvic and ulmic acids from peat have partially agonistic effect on α2-adrenergic and D2 dopamine receptors of smooth muscles
- Fulvic and ulmic acid fractions separated by pH and solvent show different effects on spontaneous contractile activity (SCA)
- Aqueous peat extract acts on smooth muscle receptors — first demonstration of specific receptor-level pharmacology for peat substances
- Guinea pig stomach smooth muscle fibers used as bioassay model
- Establishes that peat's biological effects are receptor-mediated, not just physical/chemical
Foundational pharmacology paper — the first to identify specific receptor targets for peat-derived substances. Demonstrated that water-soluble fulvic and ulmic acids act as partial agonists on α2-adrenergic and D2 dopamine receptors in smooth muscle. This paper is referenced by nearly every subsequent peat pharmacology study and establishes that peat’s therapeutic effects are receptor-mediated rather than purely physical. Listed as TIER 1 priority in the CPA-Research papers-to-find list.
