🌳 White Willow

Salix alba · Salicaceae

🌳 Temperate Europe🏔️ Mountains🌲 Boreal
🧠 To remember it"Willow heals by the water's edge what aspirin heals at the bottom of the bottle" — the bitter bark of the willow is the direct botanical ancestor of the best-selling drug in the world.
White Willow — Salix alba

🔍 Identify it without mistakes

Large tree found along riverbanks, often leaning towards the water, with gray bark deeply furrowed longitudinally on mature trees. Narrow, lanceolate, finely serrated leaves, silvery-silky underneath (hence the name "white willow"). Upright catkins appearing alongside leaves in spring, with male and female flowers on separate trees.

  1. narrow lanceolate leaves, silvery-silky underneath
  2. growth habit often leaning towards water, rapid growth
  3. gray bark deeply furrowed longitudinally when mature
  4. upright catkins appearing with the leaves (unlike goat willow, which flowers earlier)
  5. almost systematic presence directly along watercourses
Size10-25 m
FloweringApril-May
Habitatriverbanks, wetlands, pond edges, damp to waterlogged soils

⚠️ Not to be confused with

no dangerous confusion reported among willows (the genus Salix includes many species and hybrids, all sharing similar properties in their bark) (Salix spp.)aucun

To tell them apart: precise identification of the willow species matters little for the medicinal use of the bark, as salicin is present in most species of the genus in variable amounts

🍽️ Eating it

Tastevery bitter bark when brewed as a decoction

Preparation : willow is not a food; its primary use in survival is medicinal (bark) and technical (twigs)

💊 Healing with it

bark traditionally used for mild pain, feverish states, and headaches — this is the tree that gave its name to salicin, the direct historical precursor of acetylsalicylic acid (aspirin)

Level of evidence : etudes-solides (well-established use recognized by the EMA/HMPC for lower back pain, based on clinical trials using a standardized salicin extract; traditional use for fever and mild joint pain) — EMA/HMPC, community monograph Salicis cortex

⚠️ contraindicated in case of allergy to salicylates/aspirin, salicylate-sensitive asthma, or active gastric ulcer; avoid in children under 18 years old (risk of Reye's syndrome by analogy with aspirin) and when taking anticoagulant treatment

🪓 Other bushcraft uses

  • flexible twigs used in basketry since antiquity (baskets, living fences, woven structures)
  • inner bark (bast) usable as emergency cordage fiber
  • softwood historically used for artist's charcoal and homemade gunpowder charcoal
