Medicinal Tree Series: Ash 🌳✨🌿
Ash: The Enchanter (February 18 - March 17)
The third tree in the Celtic Tree Calendar series is Ash, known as "Nion" in Celtic (also spelled Nuin or Nin), symbolises connection, wisdom, strength, and the bridge between the physical and spiritual worlds. In Norse mythology, Yggdrasil, the cosmic world tree, was an Ash, highlighting its significance as a central pillar connecting different realms.
The ash tree has a long history in traditional medicine, with leaves and bark used for their anti-inflammatory, diuretic, and laxative properties. Key medicinal uses include relieving joint pain and arthritis, treating gout, promoting kidney health, and acting as a natural detoxifier, often taken as tea or extract.
Constituents: the bark of ash contains salicylates, other parts contain flavone glycosides, resins, tannins, mannitol and fruit acids.
Key Medicinal Uses and Benefits:
• Arthritis and Rheumatism: Ash bark and leaves are frequently used to relieve pain, swelling, and inflammation associated with joint issues and muscular pain.
• Diuretic and Detoxification: Leaves possess strong diuretic properties, stimulating kidney function and promoting the elimination of toxins and uric acid.
• Gout Relief: The diuretic action aids in reducing uric acid levels, making it useful for managing gout.
• Digestive Health: Historically, the bark and leaves have been used for their mild laxative effects and to treat digestive issues.
• Anti-inflammatory and Antipyretic: Used for fever reduction and reducing inflammation in various tissues.
• Skin Conditions: Historically applied to wounds and sores due to the astringent and, in some cases, anti-inflammatory properties of the bark.
Common Preparations include an infusion of the leaf (tea), a decoction of the bark, and capsules/extracts for a more concentrated effect. ☕️
⚠️ As with all medicinal plants, while ash is generally regarded as safe, it is advised to consult a healthcare provider before using, especially for conditions like chronic arthritis.
