What is Juglans cinerea?

Juglans cinerea is a homeopathic remedy. It is a single remedy, not a mix. Its Latin name is Juglans cinerea, and it is also known as Butternut.

It is made from the butternut tree, a walnut tree of eastern North America. Homeopaths use the fresh inner bark. They have used it most often for itchy skin rashes, headache, and a heavy, sore feeling under the right ribs.

The bark is watered down again and again to make the remedy. At the common 30C strength, none of the plant is left. No human trial shows it works better than a dummy pill (placebo), and long use in a tradition is not proof that something works.

How does Juglans cinerea work?

Homeopathy rests on an idea, not on a known body process. The idea is that a plant which causes signs in a well person can ease those same signs when it is watered down a great deal.

Each step of the process mixes one part of the last batch with many parts of water or alcohol, then shakes it. By 30C, the odds of even one atom of butternut being left are close to zero. There is no way we know of for a liquid to hold an effect once the plant is gone.

Low strengths are a different story. The mother tincture and strengths like 1X or 3X still hold real bark. Butternut bark is a harsh laxative (it makes you empty your bowels), so these forms can act on your gut in a real way.

When people feel better after a 30C dose, the likely reasons are the calm of the visit, time passing, and placebo. Those effects are real to the person, but they do not come from the remedy itself.

What forms does Juglans cinerea come in?

You will most often see:

Sugar pellets or tablets, sold at strengths such as 6C, 30C or 200C.

Liquid drops in an alcohol and water base.

Low strengths such as 1X or 3X, and the mother tincture, which still hold real plant matter and act on the bowel.

The raw bark is also sold as a herb outside homeopathy. That is not the same product, and it is far stronger.

Where it comes from:

Butternut bark was a common home laxative among settlers and Native peoples in eastern North America. Army doctors used it during the American Civil War.

American homeopaths took it up in the 1800s. Constantine Hering and later William Boericke listed it as a minor remedy for skin rashes, headache and right-side liver complaints. It has stayed a small, second-line remedy ever since.

What does Juglans cinerea help with?

• Itchy red skin rashes, including eczema-like patches: This is the main use homeopaths give it. Old texts describe rashes that itch more at night and after scratching. No human trial has tested homeopathic Juglans cinerea for any skin problem. If a rash is spreading, weeping or painful, see a doctor rather than treat it yourself.
• Pimple-like spots on the scalp and neck: Homeopathic texts link this remedy to crops of small, sore spots on the scalp, neck and shoulders. This comes from case reports written in the 1800s, not from trials. No published human study supports it.
• Dull headache at the back of the head: Old homeopathic books tie this remedy to a heavy headache at the base of the skull, often with a sick feeling. There is no trial evidence. A sudden, severe or first-ever bad headache needs urgent medical care, not a home remedy.
• Heavy or sore feeling under the right ribs: Homeopaths have long called this a liver remedy, based on the old use of the bark to move the bowels. That is tradition, not proof. Pain under the right ribs can come from the gallbladder or liver, so get it checked.
• Sluggish bowels (the raw bark only, not the high dilutions): The raw bark does have a real laxative effect, and that is how folk medicine used it. It can also cause cramps, watery stools and loss of body salts. Gentler options such as fibre, fluids or a pharmacy laxative are better studied and safer.

Which foods are rich in Juglans cinerea?

1. Butternuts, the oily kernels of the same tree: a food, eaten roasted or in baking
2. Maple-butternut sweets and old-style American baking, which use the kernel

Practical Tips:

Eating butternuts is not the same as taking the remedy; the remedy is made from the bark, not the nut.

What are the side effects of Juglans cinerea?

• No effects at all, which is the usual result at 30C and above
• Loose stools or watery diarrhoea, with the tincture or low strengths
• Belly cramps and wind, with the tincture or low strengths
• Nausea
• Mild stomach upset or wind from the milk sugar in pellets
• Burning or throat irritation from the alcohol in liquid drops
• Skin rash or itching in people allergic to walnuts and tree nuts
• A short flare of symptoms, which homeopaths call an aggravation

Good to know:

At 30C there is nothing in the pellets but sugar, so direct harm is very unlikely. The real risks come from two places: the low strengths and tincture, which can purge the bowel and drain body salts, and the delay that happens when someone uses this instead of care that works. Stop and get advice if diarrhoea lasts more than two days, or if any new rash spreads.

How much Juglans cinerea should you take?

• Recommended daily: There is no dose that has been proven to work, because no human trial has set one. Makers and homeopaths use their own habits, not tested figures. A common label direction for a 30C product is 3 to 5 pellets under the tongue, up to three times a day. Liquid drops are usually 5 drops in water. Follow the label on the pack you bought, or the advice of the homeopath who chose it for you. Low strengths (1X, 3X) and the mother tincture hold real bark and can purge the bowel. Do not self-dose these.
• Best time of day: Any time of day. Many labels suggest keeping it 15 minutes away from food, drink, coffee, mint toothpaste and strong smells, though this is custom rather than a tested rule.
• With or without food: Away from food, by custom. Let pellets melt under the tongue rather than swallowing them with a drink.
• Time to effect: Homeopaths expect a change within a few days for a short-term problem. There is no measured time to effect, because the remedy has not been shown to beat a dummy pill.
• How long to take it: Homeopaths usually suggest stopping once things improve. If nothing has changed after about two weeks, stop and rethink. Do not keep taking it for months for a problem that is not getting better; get it looked at instead.
