What is Vipera berus?

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.

How does Vipera berus work?

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.

What forms does Vipera berus come in?

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.

Where it comes from:

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.

What does Vipera berus help with?

• Sore, swollen veins (phlebitis): This is the classic use in homeopathic books. The picture is a vein that feels hot, tender and bursting, and feels worse when the leg hangs down. No human trials of Vipera berus for this have been published. Sore, hot, swollen veins also need a doctor, because they can point to a clot.
• Varicose veins (swollen, twisted veins near the skin): Homeopaths have used it for aching, heavy varicose veins. There is no trial evidence that it shrinks veins or eases the ache better than a dummy pill. Compression stockings, walking and weight care do have real evidence behind them.
• Heavy, puffy legs: The remedy picture includes legs that feel like they must be raised for relief. This is a traditional match of signs, not a tested result. Puffy legs can come from heart, kidney or liver problems, so get new or worsening swelling checked.
• Swollen lymph glands: Some older homeopathic texts list swollen glands with heat and tenderness. No human study has looked at this. Glands that stay swollen for more than two weeks need a doctor's opinion.
• Easy bruising and a feeling of fullness in the limbs: This use comes from what real adder venom does, read back through the "like cures like" rule. It has never been tested in people. New, easy bruising can be a sign of a blood problem and should be checked.

Which foods are rich in Vipera berus?

The pills themselves are made of milk sugar, which matters only if you cannot digest milk sugar.

What are the side effects of Vipera berus?

• Usually nothing at all at 30C, since no venom is left
• Gas, bloating or loose stools from the lactose (milk sugar) in the pills, if you cannot digest milk sugar
• Mouth or throat sting from the alcohol in liquid drops
• A short flare of symptoms, called an "aggravation" by homeopaths, which has not been shown to be real
• With very low dilutions that still hold venom: bruising, bleeding, swelling or pain

Good to know:

Side effects from the 30C pills are rare, and when they happen they usually come from the sugar or alcohol carrier rather than the remedy.

The bigger risk is not a side effect at all. It is using these pills for a hot, swollen leg or a bleeding problem and putting off care that works.

How much Vipera berus should you take?

• Recommended daily: No dose has been set by research, because no trial has shown a dose that works. Pack labels for 30C pills usually say 3 to 5 pills, two or three times a day, melted under the tongue. A homeopath may suggest a different plan. Follow the label on the pack you hold, and do not take more in the hope of a bigger effect.
• Best time of day: Any time of day. Homeopathic labels often say to keep the pills clear of food, drink, coffee and strong mint by about 15 minutes, though this is tradition rather than tested fact.
• With or without food: Usually taken away from food and drink, on an empty mouth. The pills are sugar and cause no stomach upset either way.
• Time to effect: No reliable time can be given. Any change you notice cannot be separated from placebo or from normal healing.
• How long to take it: Keep any self-treatment short. If nothing has changed within about a week, stop and see a doctor. Do not keep taking it for a leg or vein problem that is getting worse. That delay is the main real-world risk with this remedy.
