HEART STRENGTH
Three plants. One heart.
FIRRO combines three biologically active botanicals with complementary actions across the heart, circulation and nervous system.
CAYENNE
Capsicum frutescens
HEAT · CIRCULATION · AWARENESS
Capsaicin, the potent compound that gives cayenne its heat, activates TRPV1 receptors involved in vascular signalling and blood flow.
-
TRPV1 activation triggers nitric oxide and CGRP signalling, helping blood vessels dilate and supporting increased local blood flow.
-
Human studies have shown capsaicin can significantly increase skin blood flow, flow velocity and tissue oxygenation. Better circulation means more efficient delivery of oxygen and nutrients to tissues, while supporting the removal of metabolic by-products.
-
Capsaicin also activates heat-sensitive sensory nerves, producing the immediate warmth and physical sensation cayenne is known for.
-
Cayenne is the circulatory and sensory driver of FIRRO.
DAMASK ROSE
Rosa damascena
AUTONOMIC + NERVOUS SYSTEM
Damask rose contains volatile compounds, flavonoids and phenolics with measurable neurological activity.
-
Across randomized human trials, Rosa damascena preparations have been shown to reduce anxiety and stress, with studies also reporting improvements in sleep quality and reductions in mean arterial pressure.
-
A meta-analysis of 32 randomized trials found significant reductions in state anxiety, stress and depression.
-
Research points toward effects on autonomic nervous system activity and neurotransmitter signalling, giving rose a clear role in the nervous-system side of FIRRO.
HAWTHORN
Crataegus spp.
CARDIAC + VASCULAR FUNCTION
Hawthorn is one of the most extensively studied European botanicals for the cardiovascular system.
-
Its flavonoids and oligomeric procyanidins stimulate endothelial nitric oxide signalling, helping blood vessels relax and support vascular function.
-
Clinical trials and meta-analyses of standardised hawthorn extracts have shown improvements in exercise tolerance, cardiac workload and symptoms such as fatigue and shortness of breath.
-
Research also shows positive effects on endothelial function, cardiac contractility and protection of heart tissue from oxidative and ischaemic stress.
-
Hawthorn is the cardiovascular foundation of FIRRO.
THE HEART DOES NOT WORK ALONE
Heart function, circulation and nervous-system state are deeply connected. FIRRO brings all three into one formula, combining immediate sensation with longer-term daily support.
