Birch leaves contain essential oils, vitamin C and provitamin A as well as resinous and tanning substances, which have beneficial effect on human skin, making it soft and smooth. The particular advantage of a birch whisk is the fact that it helps bronchial tubes to expand, facilitating the passage of sputum and improving the lung ventilation. This is why breathing seems so easy after having hit yourself with a birch whisk in a heated sauna.
Birch whisks are particularly useful for smokers. It has been proved that the air in the birchwood is as clean as in the surgery. Whisk infusion is used for washing hair in order to strengthen it and to get rid of dandruff. Birch whisks alleviate the pain in muscles and joints after physical exercise. A fresh fragrant sauna whisk can charge you with buoyancy and good mood for many days to come.
Oak leaves contain tanning substances, which have anti-inflammatory and antiseptic action. After you relax in a heated steam room, your skin will become matte and elastic. Oak flavour hinders the extreme elevation of arterial blood pressure in the steam room, which is why the people who are prone to hypertension as well as those who do physical exercise are well advised to use oak whisks. Inhaling the oak flavour can calm nerves, relieve stress, and boost spirits.
