The use of phytopreparations in the treatment of bronchopulmonary diseases: evidence base and practical experience

Abstract

Respiratory diseases take the lead in the infectious pathology pattern of various organs and systems and are the most common. Acute bronchitis is inflammation of the bronchi due to a viral infection and is characterized by a persistent cough that can be productive or dry. The authors consider the use of herbal preparations as an effective symptomatic product for the treatment of cough of various origins. Medicinal herbs are widely used in medicine due to many useful properties and do not have any serious side effects. Ivy leaf (Hedera helix) extract preparations are common cough medicines available over the counter that are approved by the European Medicines Agency (EMA). Ivy (Hedera helix) leaves contain various biologically active components, but saponins are the main substance. Saponins are natural compounds that have a variety of biological effects. According to literature data, the action of saponins is determined not only by their bronchodilator and mucolytic properties: among additional therapeutic options of saponins are high anti-inflammatory activity, as well as antimicrobial, antifungal and antiviral effects. The article shows the potential for use of ivy saponins as carriers of pharmaceutical substances, which can significantly reduce the effective doses of certain drugs. Preparations containing ivy leaf extract are safe and approved for use even in new-borns. Also, herbal preparations with antiviral, immunomodulatory and anti-inflammatory potential become the object of study as a new strategy for treating COVID-19.
