Smooth muscle (SM) tissue contractions are involuntary movements triggered by impulses that travel through the autonomic nervous system. For example, artery walls include smooth muscle that relaxes and contracts to move blood through the body. Former studies have identified a ‘chemical effect’ of peat containing substances, which includes a stimulatory response of the spontaneous contractile activity (SCA) of SM tissue. This study sought to investigate which classes of compounds of peat ingredients could be responsible for this effect. Fulvic and ulmic acids were evaluated, and found to exert similar effects on the receptors as the peat extract. Thus, it was concluded that the agonistic effect on SM resulted from these active components, and thus may support healthy blood circulation.
