Elecampane is a tall yellow-flowered perennial whose thick, aromatic root has been dug, dried and grated in European kitchens and herb gardens for centuries. This page is for anyone who has a root, a bag of dried slices or a plant in the garden and wants to know which part to use, how to prepare it, what it tastes like, and who should leave it alone.

What it is credited with

  • Chesty, rattly coughs. This is elecampane’s oldest reputation: European herbalism has long used the root as a warming expectorant for damp winter coughs, and herbalists still reach for it in cough syrups and blends.
  • Sluggish digestion. The bitter aromatic root is traditionally taken before meals as a stomachic, and naturopathy credits it with waking up a slow appetite.
  • Bile and heavy meals. Old herbals class it as a cholagogue and choleretic, and it has a reputation for helping the stomach settle after rich food.
  • Worming remedies. In traditional European herbalism the root was one of the classic vermifuge plants, used to expel intestinal worms.
  • Itchy, irritated skin. Folk practice used a cooled decoction of the root as an external wash on itchy patches of skin.
  • Tiredness and convalescence. Herbalists have traditionally placed elecampane among the warming, invigorating roots for someone run down after a long winter.
  • Sweating it out. It is described in old texts as diaphoretic, taken hot to encourage perspiration.

Every one of these is a traditional or naturopathic reputation, not a promise. Elecampane is a flavouring and a tonic root, nothing more.

How to use it

The root is the part that matters. Use it dried and sliced, or freshly grated. Because the taste is strong and bitter, start light and blend it.

Decoction of the root (the standard preparation)

  • Put a rounded teaspoon of dried, chopped root per cup into cold water.
  • Bring slowly to the boil, then simmer gently, covered, for about ten minutes.
  • Take off the heat and leave covered for another five minutes before straining.
  • Traditionally taken as one small cup before a meal, for a short course of a week or two rather than continuously.
  • Bitter and camphorous: honey, liquorice root or a slice of fresh ginger make it far easier to drink.

Infusion of the leaves

  • A small handful of chopped dried leaves per pot of just-boiled water.
  • Cover and steep about a quarter of an hour, then strain.
  • Milder and less resinous than the root decoction; a gentler way to meet the plant.

Cough syrup and candied root

  • Simmer sliced root in water until the liquid is well flavoured, strain, then thicken with honey or sugar over low heat.
  • Keep the syrup in a sealed bottle in the fridge and use it within a few weeks, a spoonful at a time.
  • For candied root, simmer thin slices in sugar syrup until translucent, then dry them on a rack. Chopped fine, they are the classic sweetmeat taken after a heavy meal.

External wash

  • Make a strong decoction of dried root, let it cool completely and strain it well.
  • Soak a compress and wipe the itchy area, two or three times a day.
  • Test on a small patch of skin first: contact allergy to this family is not rare.

In the kitchen

  • Grated fresh root perfumes cakes, baked fruit, fruit salads and homemade liqueurs — use it as you would a spice, in pinches.
  • The yellow flowers, which look like slender dandelions, can be scattered over salads and cooked dishes as a garnish.
  • Young leaves can be cooked like a coarse green, though they are rough-textured and best chopped small.

Frequently Asked Questions

The one thing to remember: use the dried root as a short-course bitter decoction or a honey syrup, sweetened and blended, and keep the amounts small.

Which part of elecampane do I actually use?

The root and rhizome, above all — that is where the aroma and the inulin sit. The leaves make a milder infusion, and the yellow flowers are used as an edible garnish. Roots are lifted in mid to late autumn from plants at least two years old.

What does it taste like?

Strongly aromatic and bitter, with a camphor or resin note and a faintly sweet, starchy background from the inulin. Most people find it too bitter on its own. Honey, liquorice root, thyme or ginger make it pleasant, and candying the sliced root in sugar syrup is the classic solution.

Is it safe to drink every day?

Tradition treats it as a short-course root rather than a daily habit: a week or two, then a break. Excessive amounts may cause contact allergy, allergic dermatitis, cramps, diarrhoea, vomiting and even paralysis. Stop at once if a rash or stomach upset appears.

Can I take it while pregnant or breastfeeding?

No. Elecampane has a long-standing reputation for stimulating uterine contractions, so it is avoided in pregnancy and while nursing. It is also not for young children beyond a trace of grated root as a flavouring in food.

What is elecampane traditionally used for?

Its oldest reputation in European herbalism is as a warming expectorant for damp, rattly winter coughs. It is also traditionally taken as a bitter before meals for sluggish digestion, was one of the classic worming plants, and was applied cooled as a wash on itchy skin.
