Yew - Guardian of the Threshold
The yew tree (Taxus baccata) stands as one of the most paradoxical plants in Norse tradition - simultaneously the wood of life (bows, rune staves) and the harbinger of death (deadly poison). Sacred to Ullr the archer-god and Odin the death-walker, the yew bridges the worlds of the living and the dead, embodying transformation, protection, and the eternal cycle of death and rebirth.
Norse Name: Ýr (Old Norse) | Rune Association: Eihwaz (ᛇ) - Yew rune
Botanical: Taxus baccata (European Yew), Taxus brevifolia (Pacific Yew)

Traditional Preparation Methods
CRITICAL WARNING
The preparation methods below are listed for HISTORICAL and ACADEMIC purposes ONLY. NEVER attempt to prepare yew for internal use. Even external preparations can be absorbed through skin and cause poisoning. Modern practice focuses on non-toxic uses only.
Rune Stave Preparation (Safe)
Materials: Yew branch, saw, knife, sandpaper, natural oil
Safety: Wear gloves when cutting. Do not inhale sawdust. Wash hands thoroughly.
- Select straight-grained branch 1-2 inches diameter
- Cut to desired length with saw (outdoors, upwind of sawdust)
- Remove bark (bark is highly toxic - dispose safely)
- Season wood in dry place for 4-12 weeks
- Sand smooth (wear dust mask)
- Carve runes with sharp tool
- Seal with linseed oil or beeswax
Historical Toxic Preparations (DO NOT ATTEMPT)
Listed for academic knowledge only - these are LETHAL:
- Arrow Poison: Historical sources mention yew sap used to poison arrows (Germanic tribes)
- "Death Brew": Yew needles steeped in mead - used for ritual suicide or execution (Julius Caesar documented this among Gauls)
- Shamanic Trance: Some sources suggest micro-dosing yew for altered states - EXTREMELY dangerous and often fatal
- Ordeal Poison: Trial by yew - accused would drink yew tea; survival indicated innocence (most died)
Modern Understanding: There are NO safe doses of yew for internal use. Historical "survivors" were likely given placebos or different plants.
Modern Pharmaceutical Use
ONLY by medical professionals in controlled settings:
- Taxol/Paclitaxel: Chemotherapy drug derived from Pacific Yew (Taxus brevifolia)
- Cancer Treatment: Used for ovarian, breast, lung, and other cancers
- Professional Only: Requires precise dosing, medical supervision
- Side Effects: Even medicinal use has severe side effects
- Never DIY: Attempting to extract or use yew for cancer is suicide
