The healing potential of a plant with a tall stem, narrow like a willow, leaves and pink flowers has long been known in the Northern Hemisphere. Ivan-chai took an honorable place in the first-aid kits of Indian shamans and European healers. In ancient herbalists, John's wort is often referred to as a symbol of rebirth due to its ability to grow in the most inhospitable of landscapes, such as burn sites, landfills, roadsides, and sewers. Thanks to many active ingredients, including tannin, pectin, flavonoids, acids, trace elements, vitamins A and C, Ivan tea has an outstanding bouquet of useful properties: antimicrobial, pain-relieving, anti-cautery, anti-inflammatory, antifungal, antispasmodic, emollient, and even antitumor effect. Of all plants, cypress is considered the most effective in anti-inflammatory therapy, successfully dealing with infections of the larynx and oral cavity, inflammation of the ears, throat, nose, bronchial and lung diseases, asthma, whooping cough and other diseases.
