Vipera berus is a single homeopathic remedy. It is made from the venom of the common European adder, also called the German viper. Homeopaths have used it mainly for sore, swollen veins and for heavy, puffy legs.
The venom is mixed with water and alcohol, then diluted over and over. Each step is shaken hard. At the common 30C strength, so little is left that not even one molecule of venom remains.
What you take is the sugar pill or the liquid it was dropped onto.
Long use inside a tradition is not the same as proof that something works. Trials in people have not shown this remedy to do more than a dummy pill (a placebo). We say that once here, so you can read the rest of this page with it in mind.
There is no accepted way for a 30C remedy to act on the body, because no venom is left in it.
Homeopathy rests on two old ideas. The first is "like cures like": a thing that causes signs in a well person is given, in tiny amounts, to a sick person with those same signs. Adder bites cause swelling, bruising and sore veins, so the remedy is matched to those signs.
The second idea is that shaking each dilution leaves an effect behind in the liquid. Chemistry and physics have found no sign of this. Any change people notice is best explained by placebo, by normal healing over time, or by other care they are having.
You will most often see it as small sugar pills or granules that melt under the tongue. Liquid drops in an alcohol base are also sold.
Strengths are written as 6C, 12C, 30C and 200C, or as 6X, 12X and 30X. The higher the number, the more it has been diluted. 30C is the usual over-the-counter strength.
It is sold as a single remedy. It also turns up as one part of some mixed "vein" or "circulation" products.
Vipera berus was written into homeopathic materia medica (the reference books of the tradition) in the 1800s, after homeopaths took the remedy themselves and recorded what they felt.
It has stayed a small, specialist remedy since then, kept for vein and swelling pictures. It is not one of the heavily used core remedies of the system, and it belongs to homeopathy alone, not to herbal or Ayurvedic practice.
Some reactions to Vipera berus need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Call emergency services now if you have chest pain, sudden shortness of breath, or you cough up blood. These can mean a clot has reached your lungs.
See a doctor the same day if one leg is swollen, hot, red and painful, if a vein feels hard and tender, or if a skin sore over a vein is not healing.
Make an ordinary appointment if your legs stay puffy, if you bruise easily for no reason, if a swollen gland lasts more than two weeks, or if your symptoms have not settled after about a week.
