Aude origin (Occitania)

Harvested with respect from wild trees in the Pyrenees, the pure birch juice is combined with an extract of blackcurrant buds (grown and produced on-site by La Sève Cathare), and then preserved as is for several months until stabilized. The naturally occurring sugars will initiate fermentation, which will give the birch sap a slightly acidic taste. This lactic fermentation allows the sap to be preserved for several years without any addition or thermal transformation, and greatly enhances its benefits.

Birch juice has been used since ancient times for its draining and remineralizing properties. Forgotten for some time, it has made a comeback in our routines to the great benefit of our bodies.
This Elixir of Life is harvested from February to April, at the start of spring, when the sap rises in the tree to awaken the buds. A nutritious liquid, it flows through the tree's vessels, transporting water and nutrients to the branches, providing the energy required for the growth of new leaves and flowers.

🌳 Why ferment the sap?

Bio-fermentation is the preservation method that best retains nutrients, enhances nutritional value, and ensures better digestibility of its vital elements. This fermentation enriches the birch juice with vitamins and trace elements, whereas pasteurization or sterilization depletes it. The precious elixir remains alive, rich in enzymes, vitamins, minerals, and bioavailable trace elements. Probiosève (probiosap) naturally preserves at room temperature (no need to refrigerate) without any preservatives or pasteurization.

🌳 When and how to take it?

Fermented birch sap is ideal for seasonal change treatment; it pairs well with a mono-diet or a fast for a deep cleansing of the body. Its high bioavailable mineralization and richness in antioxidants provide vitality and dynamism, the blackcurrant bud extract provides flexibility and joint well-being for a true rejuvenation.

It is recommended to take 15cL (a small glass) every morning for 3 weeks.
The 3L BIB format corresponds to a 3-week cure for one person.

🌳 Blackcurrant bud extract

It is made from the blackcurrants that grow alongside birches in the Pyrenees. This is the same extract used in gemmotherapy: the buds and young shoots carry all the information of the plant, representing the plant's power in concentrated form.
The buds are left to macerate immediately after harvest in spring water, alcohol, and organic vegetable glycerin derived from Karanja oil; these three ingredients extract the various active principles from the blackcurrant buds.
Added to the birch sap, it reveals its anti-inflammatory and anti-rheumatic effects and gives it a nice hint of red fruit flavor.

bienfaits sève de bouleau fermentée 


The blackcurrant bud extract is known for its soothing effect on inflammatory pains, improving joint comfort, and strengthening the immune system. It is also a powerful drainer that pairs perfectly with birch water. It also aids the body in resisting bacterial and viral infections as well as reducing allergic inflammations.

The birch sap cure:

It will allow you to "cleanse" your body and prepare your system for the seasonal change. A "reset" due to its draining effect on the emunctories.

Assimilation: the lactic acid created during the fermentation of the sap contributes to the regulation of gastric and pancreatic juices, thus allowing better protein assimilation. Among all organic acids, lactic acid proves to be the most effective against pathogenic bacteria.

Detoxifies: the emunctories (liver, kidneys, colon, skin, and lungs) process our organic waste and expel it, so it is essential to assist them in their task and not to overburden them. A birch water cure will stimulate these organs, thus enhancing toxin elimination. It might alleviate painful joints, rheumatism, gout, and skin issues.

Drains: the most well-known effect of birch sap is its diuretic action. It increases urine production and elimination. Combined with a healthy and suitable diet, it will be your ally against cellulite and water retention. It's the right time if you're looking to "deflate"!

Remineralizes: this sap contains alkalizing minerals (especially calcium, potassium, magnesium, and silicon) and many vitamins and amino acids. Thus, it has a unique advantage: cure is not draining because it replaces some of the minerals it causes the body to lose. It also contains copper which, along with silicon, contributes to the maintenance of cartilage and bones. Additionally, it has manganese, a powerful antioxidant.

Use in cosmetics: less known for direct skin application, yet it might reduce dandruff and scalp itching due to its anti-inflammatory properties. Similarly, to combat acne or eczema, by combining both internal and external application.

After a cure, your body will be all the more receptive to the power of the foods and care you provide it with afterward!

It is not recommended for people with kidney issues. In any case, it's always best to consult a healthcare professional.
