81 Yellow Mountain-Avens
Names
Common name – Yellow Mountain-Avens
Scientific name – Dryas drummondii
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. 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. Indigenous peoples of mountainous regions have traditionally utilized these plants for various medicinal purposes, particularly for cardiovascular, urinary, and inflammatory conditions. 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. 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. Its root smells like clove.
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. It was also used as a medicine for the kidneys and bladder, its cleansing properties helping to clear infections.
A mild infusion from the leaves or whole plant brought calm to the belly and restored appetite. 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. 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. Fresh plant material could be made into poultices or washes to help wounds heal more quickly and to treat skin irritations, rashes, or infections.
Yellow Mountain-Avens was respected as a general tonic. It was said to “wake up the body” after long sickness and to bring a cooling peace to those burning with fever.

Relevant Biochemical Pathways
Anti-inflammatory Pathway
Eugenol/Flavonoids → COX-1/COX-2 inhibition → ↓ Prostaglandin synthesis → ↓ Inflammation
Antimicrobial Action
Eugenol → Bacterial cell membrane → Membrane disruption → Cell lysis → Death
Tannin Astringent Effect
Tannins + Proteins → Tannin-protein complexes → Tissue contraction → Hemostasis
Antioxidant Mechanism
Flavonoids + ROS → Flavonoid radicals + H₂O (neutralized radicals)
