Sapidity Birch Sap

The Sap of Birch contains more than 40 minerals, amino-acids, antioxidants and natural electrolytes. It is a delicate tree-water, with a neutral PH (range of 5.5 to 7.5) and a light sweet note due to Xylitol and a hint of Fructose.

Birch Sap also contains Chlorogenic Acid and Methyl Salicylate which contribute to regulate appetite, favour the absorption of fats, and so help with weight loss [1]. Birch Sap is an excellent depurative. “It neutralizes toxins, saturated fats, poly-phosphates and pesticides accumulated in the body. Naturally diuretic, it cleans the body of its uric acid, excess of salt, phosphate, urea, ammoniac and other toxins. It eases congestion in tissues, limits the water retention and fights cellulite.” [a]

Chlorogenic Acid

The Chlorogenic Acid modulates the activity of the immune system and helps to reduce the inflammation of rheumatoid arthritis [2]. The Methyl Salicylate is analgesic.
“Birch Sap has antioxidant properties and slows aging. It stimulates cell growth of dermis and skin and protects the cells of the skin against oxidative stress, ultraviolet rays, pollution and the effects of inflammation.” [a]
Flavonoids contained in Birch Sap strengthen blood vessels, decrease blood pressure and fight water retention. [3] [4] (FDA has disproved claims based on polyphenols benefits)

The Birch (lat. Betula – fam. Betulaceae) gives name to Betulin and its derivate Betulinic Acid. These two phytochemical can also be found in Alder bark (F. Betulaceae) and in Chaga mushrooms (Inonotus obliquus) which grow in symbiosis on birch trees.


By inhibiting the SREBPs (sterol regulatory element-binding protein), Betulin compromises the

biosynthesis of cholesterol and fatty acids. [5]
It is a powerful detox that has only a single problem for the pharmaceutical: Betulin is poorly soluble in water.

Betulin also shows regulating and repair effects for the liver and the skin. The cures of birch sap have centuries of tradition. The science discovers its properties only recently: Anti-sceptic, anti- fungal, anti-bacterial, anti-viral, anti-inflammatory, analgesic. [6] [7]

Betulin is an important candidate in the anti-cancer research today, and proved an efficiency cytotoxic, chemopreventive, anti-proliferative and thus by having little or no toxicity to non- cancerous cells. [8] Being new in the fight, Betulin has a remarkable action on cancer which developed resistances in classic medications.

It is an important complement for any chemotherapy. [9]

Furthermore, Betulin showed very positive results in clinical trial for treatment of hepatic wounds ( chronic HepC). [10]
It is also a complement to be considered against kidney stones, against over weigh, and skin problems (eczema among others).

Betulin and Betulinic acid have anti-retroviral properties, and are studied as a supplement to AZT in the fight and the prevention of HIV. [11] [12]

Betulin and Betulinic acid are both present in birch sap under their natural forms, in small amount easily absorbs by the human body. [13] Birch sap is of course edible (approved all over the world). It contains no common allergen. It can be consumed without moderation!

Though, people allergic to aspirin, pregnant women and people affected by serious illnesses should consult their doctor.

Dr Jean Valnet, founder of modern aromatherapy, recommends for the well-being : A cure of 1/2 to 1 glass of sap per day, on an empty stomach, during 21 days, once the year. [b]

At Sapidity we believe in the bio-balance of birch sap.
The composition of birch sap is of an incredible complexity: trace elements, amino acids, betulosides, antioxidants, xylitol, etc. …
This is the reason why we do not micro-filter our sap!
Our sap undergoes no treatment by heat ( no pasteurization).
No addition, our sap is 100% pure!
We harvest by hand, on mature and healthy wild birches.
So, Sapidity Birch Water is an alive sap, with intact all the probiotics and the enzymes which the tree needs to make its first spring leaves.

Sapidity bewares 90 days in the refrigerator (certified by laboratory). Hepatoprotector, Chemopreventive, Hypolipidemic

For the pleasure of an exceptional & hydrating water Or for a spring cure available all year round

Utilisations courantes du bois de bouleau :

  • 1re transformation : pâte, sciage (bois de grade et bois de palette), déroulage (feuilles de placages), bois de chauffage (3, 20, BB165)
  • Produits à valeur ajoutée : ébénisterie (meubles), nombreux petits articles en bois (cures-dents, abaisses-langues, bâtons de crème glacée, jouets, bobines de fil, etc.), matériaux de construction (parquets, plancher, moulures, panneaux muraux) (2, BB170)
  • Revitalisation des sites fortement perturbés.
  • Extraction de la sève pour la production de sirop (BB165); la teneur en sucre de la sève est néanmoins très inférieure à celle de l’érable à sucre : de 80 à 110 litres de sève pour produire 1 litre de sirop (ratio de l’érable: 40:1)
  • Des substances anticancéreuses et anti-VIH (bétuline, acide bétulinique) dérivées de la sève de bouleau qui contient surtout du fructose (un sucre fragile qui se dénature à > 105 °C).
  • Les peuples amérindiens utilisaient les écorces pour la fabrication de canots, d’abris, de traîneaux et de chaussures de neige de récipients étanches chez (BB165)
