Medical expert of the article
Last reviewed: 03.07.2025

This plant is quite common in the fields of Ukraine. Another thing is that not everyone knows what it looks like and what useful properties it has.
St. John's wort does not have pronounced expectorant properties, but it has good antimicrobial and anti-inflammatory effects, and also strengthens the immune system and improves the condition of the respiratory tract mucosa. All this helps reduce irritation of the inner surface of the bronchi and reduces the severity of cough.
