View Our Ingredients Glossary

Elecampane

Inula helenium

A wonderful herb to support healthy respiratory function and clear airways. It also supports elimination of excess mucus for ease of breathing. Elecampane contains compounds with antimicrobial properties, which contribute to its traditional use in supporting respiratory health. The high level of mucilage in this herb is also soothing for the mucosal lining

Menthol Crystals

Mentha arvensis

A key ingredient in our respiratory tonics, menthol crystals are derived from distilling and freezing the oils in peppermint and other mint varieties. It interacts with the cooling receptors in the nasal passages, throat and bronchial tubes to provide the sensation opening of the airways for easy breathing. When ingested, inhaled or applied topically to the skin, it has the sensation of cooling and is often used to cool skin in preparations for the chest and joints.

Licorice

Glycyrrhiza glabra

One of the most widely used and trusted herbs in traditional medicine, licorice is also available in Germany as an over-the-counter medicine. It contains glycyrrhizin, which has been scientifically studied for its benefits in supporting healthy inflammatory response and antimicrobial activity. It is also reported to promote a healthy adrenal response to stress. Used to support healthy respiratory function, digestion and healthy mood.

FAQs

It is a trusted choice for seasonal wellness, offering a fast-acting liquid formula that helps loosen stubborn mucus, soothe tight chests and supports easier breathing*. The formula is based on traditional herbal knowledge, crafted by our founder and Master Herbalist Malcolm Harker, and continues to be a consumer favorite for natural respiratory care.

Deep Lung Support Tonic is made in New Zealand using a blend of locally and globally sourced herbal ingredients. Every batch is produced to strict quality and safety standards.

Deep Lung Support Tonic has a herbal, slightly warming taste with menthol and eucalyptus notes. It contains no artificial sweeteners or flavorings.

While Deep Lung Support Tonic is a natural product, we recommend speaking to a healthcare professional before combining it with any other medications, especially those affecting the respiratory system.

This product is designed for short-term when feeling congested, constrained, and short of breath. For ongoing respiratory wellbeing, consider alternating with or using it alongside other Harker Herbals seasonal support formulas, such as Sinus Ease or Immune + Energy. Consult your healthcare provider if you wish to use it regularly.

Most people find support within a few doses, sometimes immediately, especially when taken at the first sign of congestion*. However, results may vary depending on individual response and the severity of symptoms.
