Mezereon (Daphne mezereum)

Botanical Information

  • Family: Thymelaeaceae
  • Common Names: Mezereon, Spurge Olive, February Daphne
  • Parts Used: Bark, berries (toxic—used with extreme caution)

Description

Daphne mezereum is a deciduous shrub native to Europe and parts of Asia, known for its fragrant pink-purple flowers and bright red berries. Though historically used in traditional medicine, all parts of the plant contain toxic compounds that can cause severe irritation and poisoning if not handled properly. Traditionally, it was used in external applications for rheumatic pain and skin diseases.

Historical and Traditional Uses

  • Used in European herbal medicine as an external remedy for joint and muscle pain.
  • Traditionally employed for treating stubborn skin conditions like psoriasis and eczema.
  • Historically considered a purgative and emetic in small, controlled doses.

Constituents

  • Daphnetoxin (highly toxic)
  • Mezerein (irritant)
  • Flavonoids
  • Coumarins
  • Resinous compounds

Actions

  • Counterirritant (external use)
  • Vesicant (blistering agent)
  • Analgesic (topical application)
  • Purgative (historically internal, but highly toxic)
  • Anti-inflammatory (external use)

Medicinal Uses

⚠ Use of Daphne mezereum internally is strongly discouraged due to its toxic effects. Topical use should only be conducted under expert supervision.

1. Pain Relief for Rheumatism and Arthritis:
A poultice or infusion of the bark was historically applied to affected areas to relieve joint and muscle pain.

2. Skin Conditions (External Use Only):
Traditionally applied in diluted form to stimulate blood flow and treat chronic skin ailments such as eczema and psoriasis.

3. Vesicant and Counterirritant:
Used in medieval medicine to create blisters as a means of drawing out toxins—a now outdated practice.

Preparation and Dosage

⚠ Due to its high toxicity, Daphne mezereum should NOT be taken internally.

Topical Use (Traditional Applications):

  • A weak decoction was sometimes applied to the skin for rheumatic pain relief, but this practice is now discouraged due to the risk of severe skin irritation.

Poultice:

  • Used historically for joint pain, but extreme caution is required to avoid blistering and burns.

Precautions and Contraindications

  • Toxicity Warning: All parts of the plant are toxic and can cause severe irritation, burning, vomiting, and convulsions if ingested.
  • Pregnancy and Lactation: Strictly contraindicated.
  • Skin Sensitivity: Can cause blistering, severe irritation, and chemical burns on direct contact.
  • Ingestion Risk: Even small amounts of berries or bark can cause fatal poisoning—DO NOT CONSUME.

Energetics (Traditional Medicine Perspectives)

  • Traditional Western Herbalism: Considered highly stimulating and irritating; used externally to promote circulation in stagnant conditions.
  • Traditional European Medicine: Used sparingly as a counterirritant, though largely abandoned due to its risks.

Combinations

  • For Rheumatic Pain (Historical Use): Combined with mustard or cayenne in topical applications.
  • For Skin Conditions (Historical Use): Used with diluted vinegar or herbal oils, but modern alternatives are preferred.

Harvesting and Storage

  • Harvesting: Bark was historically collected in spring; berries ripen in late summer but are highly toxic.
  • Drying: Dried bark retains its irritating properties and should be handled with gloves.
  • Storage: Store in a clearly labeled container away from children and pets.

Modern Research

Research highlights Daphne mezereum’s strong irritant and toxic effects, reinforcing its historical use as an external-only remedy and its avoidance in modern herbal practice.

Mezereon remains a historically significant but highly toxic plant, once valued for its counterirritant properties but now largely avoided due to safety concerns.
