What is Doryphora decemlineata?
Doryphora decemlineata is a homeopathic remedy made from the Colorado potato beetle. Its Latin name is Leptinotarsa decemlineata. Homeopathy books link it to burning, painful urination.
It is given as a single drug, on its own, not as part of a blend. The beetle is diluted again and again in a set way. At 30C, the usual strength, none of the beetle is left — only the sugar pill, or the water and alcohol in drops.
Trials do not show that it works better than a dummy pill. Its place rests on tradition alone, not on proof. Long use is not proof that a thing works, here or for any remedy on this page.
How does Doryphora decemlineata work?
No one has shown how it could work, and no mechanism is accepted outside homeopathy.
Homeopathy rests on an idea called 'like cures like'. A substance that causes signs in a well person is meant to ease the same signs in a sick one. Handling these beetles was said to irritate skin and the urine tract, so the beetle was chosen for urinary complaints.
The beetle is then diluted far past the point where any of it is left. A 30C pill has been diluted 30 times over, one drop in a hundred each time. Lab tests find nothing of the source in it.
Some say the water keeps a 'memory' of what was once in it. There is no accepted proof of that idea. When trials compare these pills with dummy pills, the two come out the same.
What forms does Doryphora decemlineata come in?
You will most often see small sugar pills or granules that melt under the tongue. Liquid dilutions in water and alcohol are also sold, taken as drops.
Common strengths are 6C, 30C and 200C. The higher the number, the more times it has been diluted, and the less of the source is left. A 30C pill is the usual retail choice.
Mother tinctures and very low strengths such as 1X to 3X are not general retail items for this beetle.
Where it comes from:
The Colorado potato beetle spread fast across North America in the middle of the 1800s as potato farming grew. American homeopaths of that era tested many local plants, animals and insects.
Doryphora decemlineata entered homeopathic reference books in the late 1800s. Writers of the time described stinging, burning urination and a constant urge to pass water.
It has always been a small remedy. It is used far less than staples such as Cantharis, and it belongs to one tradition only.
Who should avoid Doryphora decemlineata?
- Do not use this instead of antibiotics if a doctor has told you that you have a urine infection.
- Never use the mother tincture or any strength weaker than 4C, as these can still contain real beetle matter.
- Do not use it to treat a child under 2 without speaking to a doctor first.
- Never give the alcohol-based liquid drops to a baby or young child; use the pills if a remedy is used at all.
- Do not use the liquid drops if you take disulfiram or metronidazole, or if you are avoiding all alcohol.
- Do not use the pills if you have a known allergy to lactose (milk sugar) or to cane sugar.
- Do not use it if you are pregnant or breastfeeding unless your doctor or midwife says it is fine.
- Do not use it to treat blood in your urine, fever with back pain, or an inability to pass urine — these need a doctor the same day.
- Do not use it alongside a chronic kidney or bladder condition without telling the doctor who treats you.
When should you see a doctor?
See a doctor the same day if you have a fever, chills, pain in your side or lower back, blood in your urine, or vomiting along with urinary pain. Go to an emergency department if you cannot pass urine at all, or if you get swelling of the lips, face or throat, a spreading rash, or trouble breathing after taking any product. Also see a doctor if burning or urgency has not settled within 3 days, if it keeps coming back, or if you are pregnant, have diabetes, or have a known kidney problem.
