What is Serum anguillae?

Serum anguillae is a homeopathic remedy. It is made from the blood serum of the eel. Serum is the clear liquid part of blood.

It is a single drug in homeopathy. The Latin name is Anguilla anguilla (blood serum). Many people know it as eel serum.

Homeopaths have used it for kidney trouble and for a build-up of water in the body. It was also used for swollen legs and for low urine output. These uses come from old practice, and old practice is not proof that something works.

The remedy is diluted over and over again. At 30C no eel serum is left at all. Trials do not show it doing more than a dummy pill (placebo).

How does Serum anguillae work?

There is no known way this remedy could act on the body. That is the honest answer, and it comes first.

Homeopathy rests on an idea called 'like cures like'. Raw eel blood harms red blood cells and the kidneys. So homeopaths give a tiny, diluted dose for kidney and water problems.

The maker mixes one part eel serum with 99 parts liquid. Then they shake the mix hard. This shaking step is called succussion.

The step is then repeated many times. A 30C remedy has been through 30 such steps. By that point no eel serum remains in the bottle.

What you swallow is sugar, or water and alcohol. Homeopaths say the liquid keeps a 'memory' of the eel serum. Chemists and doctors have found no sign of such a memory.

When these remedies are tested against a dummy pill, they match it. So any change you feel is likely due to time, care, or your own hopes.

What forms does Serum anguillae come in?

You will mostly find it as small sugar pills. They melt under the tongue.

Other common forms are:

Sugar pellets in a tube, often 6C, 30C or 200C. Liquid drops in water and alcohol. Larger tablets that dissolve in the mouth.

It is a rare remedy. Most shops do not stock it, so it is often ordered from a homeopathic pharmacy.

There is no injection form for home use. Raw eel serum is not sold as a supplement, and it should never be taken raw.

Where it comes from:

Eel serum came into homeopathy from French lab work, not from folk medicine.

Around 1900, French scientists showed that eel blood was toxic. It damaged red blood cells and harmed the kidneys in animals.

French homeopaths then turned it into a remedy. They gave it for kidney trouble and for water held in the body. This followed the 'like cures like' rule.

It has stayed a small, rarely used remedy. It sits in some homeopathic reference books. You will not find it in most home kits.

So its traditional standing is real but narrow. It belongs to one tradition, and only to a small corner of it.

What does Serum anguillae help with?

• Kidney inflammation (nephritis): This is the classic use in homeopathic books. It was chosen because raw eel serum harms the kidneys. No human trial has tested the remedy for kidney disease. Kidney inflammation needs a doctor and real tests, such as blood and urine checks.
• Water held in the body (oedema): Homeopaths used it when fluid gathered in the legs or belly. There is no trial evidence for this. Fluid build-up can be a sign of heart, kidney or liver trouble, so it needs a proper check.
• Swollen ankles and legs: Old texts describe puffy, heavy legs as a guiding sign for this remedy. That is a traditional picture, not a tested result. New or one-sided swelling can mean a blood clot and needs same-day care.
• Low urine output: Books list scanty, dark urine as a key sign. No study has looked at whether the remedy changes urine output in people. Passing very little urine can be a sign the kidneys are failing.
• High blood pressure (hypertension): Some homeopathic sources link this remedy to raised blood pressure with kidney strain. There is no human trial support. High blood pressure is silent and needs measuring and proven treatment.
• Shortness of breath linked to heart strain: A few texts mention breathlessness with swelling. This is traditional guidance only. Breathlessness is a warning sign and should be checked by a doctor, not self-treated.

Which foods are rich in Serum anguillae?

1. Cooked eel: the meat is a normal food, and heat destroys the toxin found in raw eel blood

Practical Tips:

Never eat or drink raw eel blood or raw eel serum; it is poisonous. Cooked eel is a food, not a remedy.

What are the side effects of Serum anguillae?

• No effect at all, which is the usual outcome
• A short flare of symptoms soon after starting (homeopaths call this an aggravation)
• Upset stomach in people who react to milk sugar (lactose) in the pellets
• Mouth or throat stinging from the alcohol in liquid drops
• Rash, itching or swelling in people allergic to fish
• Harm from delay, if it is used in place of needed treatment

Good to know:

Direct side effects are very unlikely. At 30C there is nothing in the pill but sugar.

The real risk is delay. Kidney disease, heart strain and fluid build-up get worse without proper care.

Allergy is only a worry with very low potencies, which may still hold traces of eel protein. If you are allergic to fish, avoid these.

How much Serum anguillae should you take?

• Recommended daily: No dose has been shown to work. There is no proven daily amount. In common homeopathic practice, people take 3 to 5 pellets of a 30C potency. Some take it once a day. Others take it only now and then. Let the pellets melt under the tongue. Do not chew them. Because a 30C pellet holds no eel serum, the amount you take does not change what is in it. A bigger dose is still sugar.
• Best time of day: There is no set time of day. Homeopaths often suggest taking it in the morning, away from meals.
• With or without food: Usually taken on its own, about 15 to 30 minutes before or after food and drink. Homeopaths also suggest avoiding strong tastes like mint or coffee near the dose. This is custom, not a tested rule.
• Time to effect: No reliable time frame exists, because no trial has measured one. Homeopaths often say days to weeks. Any change you notice may simply be the illness running its course.
• How long to take it: Keep any trial short. Two to four weeks is enough to judge it. Stop and rethink if nothing has changed. Do not keep going for months. See a doctor at once if your symptoms get worse at any point. Swelling, breathlessness and kidney symptoms should never be left to a remedy alone.
