What studies say about the benefits

1. Cough relief and mucous membrane protection - contains more than 50% mucilage (lichenin and isolichenin), which coat and soothe irritated mucous membranes in the mouth, throat and gastrointestinal tract. It is effective for dry, irritating coughs, bronchitis and whooping cough.

2. Anti-inflammatory and antimicrobial activity - lichen acids, such as usnic acid, have antibacterial, antiviral and antifungal effects. They inhibit the growth of bacteria, including Helicobacter pylori , and have immunostimulating effects.

3. Digestive support - bitter substances (cetrarin) stimulate appetite, regulate the secretion of stomach acid and bile, and relieve digestive disorders.

4. Strengthening the body - due to its content of vitamins (e.g. B12), iodine and iron, it helps with anemia, exhaustion and recovery from illness .
