Ivan chai is made from environmentally friendly raw materials collected by residents of the Tomsk region. Blooming sally contains vitamin C and B, polysarahid, carotene and pectin, organic acids, macro-and micronutrients.

Ingredients: fermented leaf of black-headed fireweed,  lingonberry leaves.

Lingonberry has not only an original taste with a slight bitterness, but also stores a lot of elements and compounds that are simply necessary for the human body: organic acids, vitamins, pectin substances and tannins.

Lingonberry CONTAINS:

vitamins A, B, C, E, K1
potassium, copper, calcium, iron, phosphorus, manganese, zinc
pectin and tannins, flavonoids (catechins)
organic acids (about 2%): citric, acetic, malic, formic, oxalic, benzoic, glyoxylic, pyruvic, oxypyruvic, oxoglutaric
sugar (up to 10%): glucose, fructose.
The copper found in the berries and leaves of lingonberries makes them useful for treating diabetes.
Manganese has a positive effect on the function of the hematopoietic organs, takes part in carbohydrate metabolism (necessary for the secretion of insulin – a hormone of the pancreas), participates in lipid metabolism (prevents the deposition of fat in the liver) and cholesterol synthesis.
Benzoic acid is a natural antioxidant that strengthens the cell membranes in the body. The presence of tartaric and salicylic acids in lingonberry berries allows them to be used as an antirheumatic agent. Lingonberry skins contain ursolic acid. This acid has a hormonal effect, similar in nature to the action of hormones in the adrenal cortex. These hormones have anti-stress effects.

avitaminosis
