General Information:

Yellow Mountain-Avens represents a group of alpine plants that include both Geum montanum (Alpine Avens) and Dryas drummondii (Yellow Mountain Avens), both belonging to the Rosaceae family. ^[4] These hardy perennial herbs thrive in mountainous and arctic regions across North America and Europe, adapting to harsh alpine conditions with their low-growing, mat-forming habit. ^{[4, 5]} Indigenous peoples of mountainous regions have traditionally utilized these plants for various medicinal purposes, particularly for cardiovascular, urinary, and inflammatory conditions. ^{[1, 5]} The plants’ distinctive yellow flowers and their ability to survive in extreme alpine environments have made them culturally significant as symbols of resilience and healing. ^[5] The medicinal properties of these species are attributed to their rich content of tannins, phenolic compounds, and essential oils, which contribute to their astringent, anti-inflammatory, and antimicrobial therapeutic effects. ^{[2, 3, 6]} Its root smells like clove. ^[3]

Traditional Indigenous Uses

Its roots and leaves could be made into a tea or decoction to help those suffering from heart weakness or poor circulation. ^[1] It was also used as a medicine for the kidneys and bladder, its cleansing properties helping to clear infections. ^[1]

A mild infusion from the leaves or whole plant brought calm to the belly and restored appetite. ^[1] For coughs, chest congestion, and inflammation in the lungs, the leaves and flowers were boiled into teas or used as steam inhalations to clear the airways. ^[1] Its roots, when prepared as a stronger decoction, were taken to ease the aches of rheumatism and arthritis or applied to sore joints and muscles to reduce swelling. ^{[1, 5]} Fresh plant material could be made into poultices or washes to help wounds heal more quickly and to treat skin irritations, rashes, or infections. ^{[1, 5]}

Yellow Mountain-Avens was respected as a general tonic. ^[1] It was said to “wake up the body” after long sickness and to bring a cooling peace to those burning with fever. ^[1]

Mechanism of Action

Cardiovascular Support

• Vasodilation by flavonoids and phenolic compounds
• Antioxidant protection prevents cardiovascular damage
• Anti-inflammatory effects in vascular tissues
• Cardiotonic effects by specific glycosides ^[2]

Anti-inflammatory Properties

• Cyclooxygenase (COX) inhibition by flavonoids and eugenol
• Lipoxygenase inhibition by phenolic compounds
• Nuclear factor-κB (NF-κB) pathway modulation
• Cytokine production reduction (TNF-α, IL-1β, IL-6) ^{[2, 6]}

Antimicrobial Activity

• Cell membrane disruption by eugenol and essential oils
• Protein binding by tannins
• DNA/RNA synthesis inhibition by phenolic compounds
• Biofilm formation inhibition ^{[2, 3]}

Astringent and Wound Healing

• Protein precipitation by tannins
• Tissue contraction and bleeding control
• Antimicrobial barrier formation
• Collagen synthesis stimulation ^[2]

Urinary Tract Support

• Diuretic effects by flavonoids
• Anti-inflammatory action in urinary tissues
• Antimicrobial activity against urinary pathogens
• Tissue healing support ^[2]

Relevant Biochemical Pathways

Anti-inflammatory Pathway

Eugenol/Flavonoids → COX-1/COX-2 inhibition → ↓ Prostaglandin synthesis → ↓ Inflammation ^{[2, 6]}

Antimicrobial Action

Eugenol → Bacterial cell membrane → Membrane disruption → Cell lysis → Death ^[3]

Tannin Astringent Effect Tannins + Proteins → Tannin-protein complexes → Tissue contraction → Hemostasis ^[2] Antioxidant Mechanism

Flavonoids + ROS → Flavonoid radicals + H₂O (neutralized radicals) ^[2]
