What is Ranunculus bulbosus?

Ranunculus bulbosus is a single homeopathic remedy made from the bulbous buttercup, a wild meadow plant. Homeopaths give it most often for sharp, stabbing pain in the chest wall and ribs. It is also a classic homeopathic choice for shingles, a painful blistering rash.

The remedy is made by diluting the plant juice again and again, with shaking at each step. At 30C, the strength most shops sell, no plant matter is left at all. What you take is sugar and water.

Trials have not shown that homeopathic pills work better than a dummy pill. The remedy has a long place in homeopathic books, but long use is not proof that something works. Read the rest of this page with that in mind.

How does Ranunculus bulbosus work?

There is no known body process that explains how this remedy could act. At 30C there is nothing of the plant left to act.

Homeopathy rests on an old idea called 'like cures like'. A substance that causes symptoms in a well person is said to treat those same symptoms once it is heavily diluted. Fresh buttercup sap raises blisters and causes burning, stinging pain.

That is why homeopaths matched it to blistering rashes and stabbing nerve pain. This is a matching rule, not a tested mechanism. Any relief people report is best explained by time, care and the placebo effect.

What forms does Ranunculus bulbosus come in?

Most people take small sugar pellets that melt under the tongue. Liquid drops in alcohol and water are also sold.

Common strengths are 6C, 12C and 30C. The 'C' means each step dilutes the mix 100 times over.

Mother tincture and 1X or 2X strengths are different. They still hold plant material and can burn or blister. Do not treat them as the same thing as a 30C pellet.

Where it comes from:

The bulbous buttercup grows in meadows across Europe and has long been known as a plant that burns the skin. Followers of Samuel Hahnemann tested it in the early 1800s and wrote up what they saw.

It has stayed a standard entry in homeopathic texts since then. It is best known there for rib and chest wall pain and for shingles. Its standing is inside homeopathy only, not in herbal medicine.

What does Ranunculus bulbosus help with?

• Sharp pain in the chest wall and between the ribs: This is the best known homeopathic use. Books describe stitching pain that gets worse when you move, breathe deeply or turn over in bed. No human trial has tested the remedy for this pain. Chest pain always needs a doctor's opinion first, because some causes are dangerous.
• Shingles (a painful blistering rash caused by a virus): Homeopaths pick it for tight clusters of blue-tinged blisters with burning, stinging pain. There is no trial evidence that it helps. Shingles has proven antiviral treatment that works best in the first three days, so see a doctor quickly.
• Blistering skin rashes: The match comes from the way the fresh plant raises blisters on skin. That is a matching rule in homeopathy, not a tested effect. No human studies support this use.
• Rib and back pain that feels worse in cold, damp weather: Homeopathic texts stress pain that flares in cold, wet weather and eases with warmth. This is traditional description only. Lasting back or rib pain should be checked by a doctor.
• Eye strain with sharp, stabbing pain: An older book use, linked to close work in poor light. There is no research behind it. Eye pain with changed vision needs urgent medical care.
• Hard skin and corns on the feet: A minor traditional use in homeopathic texts. No trials exist. Simple foot care and proper shoes are better first steps.

Which foods are rich in Ranunculus bulbosus?

Never eat buttercup leaves, flowers or bulbs, and never add them to a salad or tea.

What are the side effects of Ranunculus bulbosus?

• Nothing expected from 30C pellets beyond the sugar they are made of
• Burning in the mouth or throat from mother tincture or very low strengths
• Blisters and redness if fresh plant sap touches the skin
• Stomach upset from alcohol-based drops in people with a sensitive stomach
• Rare allergic rash in people who react to plants in the buttercup family
• A short flare of symptoms, which homeopaths call an aggravation
• Harm from putting off treatment that works

Good to know:

Side effects from 30C pellets are very unlikely. There is nothing in them but sugar and water.

The real risk sits with the fresh plant and the least diluted forms. Those can burn the mouth and blister the skin.

The biggest risk with any homeopathic remedy is a delay in proper care. Shingles, chest pain and eye pain all need a doctor.

How much Ranunculus bulbosus should you take?

• Recommended daily: There is no proven dose. No trial has set a dose for this remedy, so nothing here is backed by evidence. Packs of 30C pellets often say to take three to five pellets under the tongue, two or three times a day. Homeopaths often give fewer doses than that and stop as soon as symptoms ease. Do not use the mother tincture or 1X drops at home. Those forms can still hold the plant chemical that burns skin and the mouth.
• Best time of day: Any time of day. Homeopaths often suggest keeping it away from strong tastes such as mint, coffee or tobacco, but this is custom and has not been tested.
• With or without food: Usually taken between meals, about 15 minutes before or after food or drink. This is homeopathic custom rather than a tested rule.
• Time to effect: No honest time can be given, because the remedy has not been shown to do anything. Any change you notice is most likely the illness settling on its own.
• How long to take it: Keep any trial short. Three to five days is enough for a short-term problem. If nothing has changed after about three days, stop and see a doctor. Do not keep taking it for weeks for a problem that is not getting better.
