What is Menyanthes trifoliata?
Menyanthes trifoliata is a single homeopathic remedy. It is made from bogbean, also called buckbean, a marsh plant with leaves in sets of three. Homeopaths have used it most often for face pain, pressing headache and aching joints.
The remedy is made by diluting the plant again and again, with hard shaking at each step. At 30C, no atoms of the plant are left in the pill or the drops. Only the sugar pellet or the water and alcohol remain.
Tests in people do not show that it works better than a placebo (a dummy pill). It has a long place in homeopathic books, but that record on its own is not proof that it acts on the body. That is true for every claim on this page, so we say it here once.
How does Menyanthes trifoliata work?
There is no known way for a 30C dilution to act on the body, because nothing of the plant is left in it.
Homeopathy rests on the idea that a very small dose can ease the same symptoms that a large dose would cause. Homeopaths say the water keeps a trace of the plant after shaking. Chemists and physicists have found no sign of that trace, and no test has shown it.
What people notice is best explained by the placebo effect, by the calm of a long talk with a practitioner, and by the fact that many aches settle on their own with time.
Low potencies and the mother tincture are different. They still hold real plant matter, and bogbean is a strong bitter. Bitters can make you salivate and can stir up the stomach, which is why large doses cause vomiting.
What forms does Menyanthes trifoliata come in?
You will find Menyanthes trifoliata sold as:
Sugar pellets or tiny globules that melt under the tongue.
Liquid drops in water and alcohol.
Mother tincture, marked Q or MT, which is the strong plant extract before dilution. This one still holds real bogbean.
Common strengths are 6C, 30C and 200C, and sometimes 6X or 12X. The higher the number, the more it has been diluted. From 12C upward, no plant matter is left.
Where it comes from:
Bogbean grows in bogs and pond edges across Europe, northern Asia and North America. Country healers in Britain, Ireland and Scandinavia made a bitter tea from the leaf for poor appetite, weak digestion, scurvy and aching joints. Brewers once used it in place of hops.
Homeopaths proved the plant in the 1800s, early in the life of homeopathy. It became a small remedy, kept for pressing pain in the face and head that eases with hard pressure. It has never been a leading homeopathic medicine.
Who should avoid Menyanthes trifoliata?
- Do not use if you are allergic to bogbean, buckbean or other plants in the bogbean family.
- Do not take bogbean mother tincture, strong extract or bogbean tea if you are pregnant or breastfeeding.
- Do not take the mother tincture if you have a peptic ulcer (a sore in the stomach lining), gastritis (an inflamed stomach), or diarrhoea that will not settle.
- Do not take any bogbean extract if you use warfarin or another blood thinner, unless your doctor says it is fine.
- Do not use alcohol-based drops if you avoid alcohol, are in recovery, or take a medicine that must not be mixed with alcohol.
- Never replace a medicine your doctor prescribed with this remedy, and never delay urgent care to try it first.
- Do not give pellets to a child under 3 years old without asking a doctor, because small pills are a choking risk.
- Do not use it for a new, severe or one-sided face pain until a doctor has looked at it.
When should you see a doctor?
See a doctor if your face pain is new, severe, or comes with a droopy face, blurred vision or numbness. Get help straight away for a headache that hits suddenly and is the worst you have had, or one that comes with fever, a stiff neck, a rash or confusion.
Also book an appointment if a joint is hot, red and swollen, if you have fever or weight loss you cannot explain, or if your symptom is no better after one to two weeks.
If you have taken bogbean tincture and cannot stop vomiting, or you have bad stomach pain, call your doctor or a poison line.
