7 ways to use lye
Choose a treatment
Every treatment draws on the same thing — stabilised Black Sea lye or products made with it. The difference lies in how the lye reaches the skin.

Before you begin
Four rules for every treatment
Heat only in a water bath
Place the container of lye in a larger vessel of warm water until it reaches 38–40 °C. Do not use a microwave oven.
38–40 °CApply to clean skin
After a shower, the pores are open and the minerals from the lye penetrate more easily.
After showerFirst, try on a small area
Lye is highly concentrated. If there is a scratch or a small wound on the skin, it will sting.
The first treatmentIf you are unwell — see a doctor first
If you have high blood pressure, heart disease, are pregnant, or have an acute inflammation or a fever, consult your doctor.
Important01Warm or cold — on the affected area
Lye compresses
The most popular lye procedure to do at home. The compress holds the lye on the painful joint or along the affected nerve long enough to take effect — from 15 minutes to several hours.
- Temperature
- 38–40 °C, in a water bath
- Stay
- 15 min – several hours
- Course
- 12–14 treatments
- Where
- Home
How to make a lye compress
- Warm the lye in a water bath to around 38–40 °C — as warm as bath water.
- Soak a cotton cloth in the warm lye. Gauze, a cotton cloth or an old cotton T-shirt will all do.
- Apply the compress. Wrap the painful joint twice, or lay the cloth along the affected nerve.
- Insulate. Cover with plastic or cling film and then with a towel or a woollen cloth to retain the heat.
- Leave on for 15 minutes to several hours. For lasting results, complete a course of 12–14 procedures.
Cold compress
If you cannot tolerate a warm compress or you have varicose veins, follow the same steps using unheated lye.
Even easier: a lye applicator
The body applicator is a cotton cloth already soaked in lye and sealed in a sachet — you need neither a cloth nor a container for the lye.
- Place the sachet in a bowl of warm water (38–40 °C) for 3–5 minutes.
- Take out the warmed cloth and place it along the nerve or around the painful joint.
- Insulate with plastic and wrap in a towel or a woollen cloth — from 15 minutes to several hours.
Do not heat the applicator in a microwave oven. If you have varicose veins, use it cold.
02Local or full-body
Lye massage
The easiest way to use lye at home — no equipment needed at all. Lye massage gels and oils combine the minerals of the lake with essential oils and herbal extracts.
- Technique
- Rub in with circular movements
- Stay
- 20 min – several hours
- Where
- Home
- Suitable
- After sport, for muscle stiffness
How to give a lye massage
- Apply a lye gel or oil — over the whole body or only on painful and stiff areas.
- Rub in with gentle circular movements until the product is spread evenly.
- Leave it to absorb — from 20 minutes to several hours. Once the water evaporates, only the salt remains on the skin.
What lye adds to a massage
- speeds up the metabolism;
- helps balance the nervous and muscular systems;
- relieves muscle pain;
- protects against cramps;
- nourishes and strengthens the skin, hair and nails.
Do you work at a computer all day?
Pain in the wrist, elbow and back has become a "modern" complaint. Rub lye massage gel into the arm you use for the mouse, from wrist to elbow — and carry on working. Your arm recovers while you use it.
Do you play sport?
More and more sports doctors use lye products in recovery procedures after training and matches. Lye is a concentrate of magnesium — the mineral muscles need after exertion — and massage delivers it exactly where it hurts.
03For the whole body or just the feet
Lye baths
A lye bath relaxes the muscles, remineralises and soothes the whole body. It relieves fatigue and tension and improves tone — and it is done in an ordinary bath at home.
- Quantity
- 0.5–2 l of lye in the bath
- Water
- До 38 °C
- Stay
- 15–20 min
- Caution
- With high blood pressure — consult a doctor
Full-body bath
- Fill the bath with 60–70 litres of water, no warmer than 38 °C.
- Pour in 500–2000 ml of stabilised Black Sea lye and stir.
- Relax in the water for 15–20 minutes.
- Rinse your skin thoroughly with clean water.
Local baths for hands and feet
Dissolve 50–100 ml of lye in 5–10 litres of water and soak your hands or feet for 10–15 minutes.
- Warm bath (around 38 °C) — for colds.
- Cold bath — for swollen legs or varicose veins.
Make your bath even more enjoyable: add a few drops of essential oil — juniper, lavender or another of your choice.
If you have high blood pressure, take lye baths only under medical supervision.
04Sponge or cloth rub-down
Lye frictions
A friction is a rub-down of the body with a sponge or cloth soaked in lye. It is done on clean skin after a shower — the pores are then open and the minerals and trace elements in the lye penetrate more easily.
- Dilution
- От 1:10 до 1:1
- Stay
- 5–6 min
- When
- After shower
- After
- Rinsing with water

How to do lye frictions
- Take a shower so that your skin is clean and your pores are open.
- Soak a sponge or cloth in diluted lye. For the first few times start with a weak solution — 1 part lye to 10 parts water. That is exactly the amount of lye in ANCHIALO shower gel.
- Rub down the whole body and leave the lye to work for 5–6 minutes.
- Rinse thoroughly with water.
- Build up gradually. Increase the concentration with each following procedure — up to 1:1. How strong a solution you use depends on how sensitive your skin is.
What to use
- ANCHIALO shower gel with 10% lye — created especially for frictions;
- stabilised Black Sea lye, diluted with water;
- body applicator — a cotton cloth already soaked in lye;
- massage gel or massage oil with lye.
05Teeth, gums and fresh breath
Lye for oral hygiene
Studies show the beneficial effect of lye on the whole oral cavity: it strengthens tooth enamel, reduces swelling of the gums and maintains the normal acid-alkaline balance in the mouth. You can use it every day.
- Toothpaste
- Instead of the ordinary
- Mouthwash
- With 10% lye
- Rinsing
- Lye 1:1 to 1:10
- How often
- Every day

How to use it
- ANCHIALO toothpaste with Black Sea lye — for daily brushing;
- ANCHIALO mouthwash with 10% Black Sea lye — after brushing;
- ANCHIALO stabilised lye — dilute with water from 1:1 to 1:10 and rinse your mouth.
What lye does in the mouth
- normalises saliva function;
- increases the resistance of tooth enamel and helps strengthen it — protecting against tooth decay;
- maintains the normal acid-alkaline balance in the oral cavity;
- reduces swelling of the gums.
What the research shows
Lye inhibits the growth of the microorganisms Staphylococcus aureus, Staphylococcus haemolyticus, Lactobacterium casei and Candida albicans sufficiently to maintain a normal oral microflora.
Preclinical studies
- good local tolerance;
- no allergenic or toxic properties;
- no irritant effect.
Clinical studies
- 59% lower likelihood of new caries;
- cleansing action on dental plaque — 60%; the plaque index (Green–Vermillion) falls by 31.5%;
- rapid effect in gingivitis, stops bleeding gums;
- 71% milder manifestations of periodontal disease.
Expert opinion
"Pharmacological studies of medicinal lye show that it has good biological tolerance, a stimulating effect on the enzyme activity of saliva and protects the tissue surface of the oral cavity, i.e. it activates the natural immune defence mechanisms in the mouth."

06For inflammation of the upper respiratory tract
Lye inhalations
A solution of lye and distilled water is inhaled using a nebuliser, so it reaches the airways and lungs directly. It helps with chronic bronchitis and various respiratory problems.
- Solution
- 2–5% lye in distilled water
- Device
- Inhaler (nebuliser)
- Where
- At home or in the clinic
How to prepare the solution
| Solution | Lye | Distilled water |
|---|---|---|
| 2% | 2 ml | 98 ml |
| 5% | 5 ml | 95 ml |
- Mix the lye with distilled water in the ratio given in the table. Start with the weaker, 2% solution.
- Pour the solution into the nebuliser following the device's instructions.
- Breathe calmly through the mask or mouthpiece.
Use distilled water only, not tap water. If you have a chronic condition, or for children, consult a doctor first.
07Phonophoresis with lye
Ultrasound therapy with lye
Ultrasound helps lye penetrate deeper into the skin, significantly enhancing its beneficial effect. The procedure is carried out by a physiotherapist and takes around 10 minutes.
- Duration
- Approx. 10 min
- Where
- Physiotherapy Practice
- Other name
- Phonophoresis
What it helps with
- peripheral nervous system problems;
- after-effects of central nervous system damage;
- musculoskeletal injuries;
- gastrointestinal problems;
- chronic inflammatory processes in various organs and tissues;

1:10Frequently Asked Questions
Questions about lye treatments
How many lye treatments are needed?
For compresses we recommend a course of 12–14 treatments. Massage with gel or oil, baths and oral hygiene products are suitable for regular use.
Should lye be diluted?
It depends on the procedure. For a compress, undiluted lye is used, while the gel and the massage oil are ready to use. For rubs — from 1:10 to 1:1; for mouth rinsing — from 1:1 to 1:10; for gargling — from 1:5 to 1:10; for inhalations — a 2–5% solution with distilled water. For a bath, pour in between 0.5 and 2 litres.
How do I warm the lye?
Only in a water bath: place the bottle or container of lye in a larger vessel of warm water until it reaches 38–40 °C. Do not heat it in a microwave oven.
Should I use a warm or a cold compress?
The warm compress is the classic option. Choose a cold one — with unheated lye — if you cannot tolerate heat or have varicose veins.
Do I need to rinse off after the treatment?
After a bath or a friction rub — yes, rinse thoroughly with clean water. After a massage you can leave the gel or the oil to absorb: once the water evaporates, only the salt remains on the skin.
Why does lye sting?
Lye is a highly concentrated saline solution. If your skin has a scratch, a small wound or any irritation, you will feel a stinging sensation. That is why, for your first treatment, you should try it on a small area, and when doing rubs, start with a weak 1:10 solution.
Can I use lye treatments if I have high blood pressure?
Lye baths for hypertension should only be taken under medical supervision. If you have a chronic or cardiac condition, are pregnant, or have an acute inflammation, consult your doctor before every treatment.
How does lye differ from liman mud?
Lye is the liquid concentrate left behind in the salt pans once the seawater has evaporated and the salt has crystallised. Liman mud is the silt from the bottom of Lake Pomorie. The two are used together in mud therapy — see What is lye? and Pomorie liman mud.
