Respiratory Health

Several botanical ingredients have documented research support for respiratory health. Astragalus, one of the key ingredients in our Vertigo Comfort formula, has been studied for its immunomodulatory properties and shown in clinical research to strengthen the body's resistance to respiratory infections. Licorice root contains glycyrrhizin, a compound with anti-inflammatory and antiviral properties that has been used in traditional medicine across Asia and Europe for centuries to soothe bronchial passages and reduce mucus viscosity. These ingredients work by supporting immune resilience and reducing inflammatory irritation in the airway rather than suppressing symptoms with pharmaceutical compounds.

Astragalus membranaceus has one of the most extensive research profiles of any immune-supportive botanical. Studies published in the Journal of Ethnopharmacology show that astragalus polysaccharides stimulate the production of T lymphocytes and natural killer cells, the immune cells responsible for identifying and clearing respiratory pathogens. Multiple clinical trials in China, where astragalus has been used medicinally for over 2000 years, show reduced severity and duration of upper respiratory infections in people taking astragalus extract regularly. Its mechanism differs from vitamin C in that it directly modulates cellular immunity rather than acting as a general antioxidant.

Licorice root (Glycyrrhiza glabra) has a well-documented traditional use for respiratory conditions including coughs, bronchitis, and asthmatic irritation. Its active compound glycyrrhizin inhibits phospholipase A2, an enzyme involved in the inflammatory cascade that produces bronchial irritation and mucus overproduction. Research in the journal Phytotherapy Research found licorice extract reduced airway inflammation markers in animal models of bronchial inflammation. In humans, licorice preparations have been used in clinical settings in Japan for liver support and inflammatory conditions for decades. Daily supplementation at moderate doses is generally well-tolerated in healthy adults, though those with high blood pressure should consult a doctor before use.

The botanical ingredients in this collection support respiratory health through immune and anti-inflammatory pathways rather than acting as bronchodilators or respiratory medications. They are not suitable replacements for prescribed inhalers, corticosteroids, or antibiotics for diagnosed respiratory conditions such as asthma or COPD. For general immune maintenance and mild seasonal respiratory support in otherwise healthy adults, these supplements provide a research-backed botanical approach.

If you have a diagnosed respiratory condition or take respiratory medications, consult your pulmonologist or GP before adding any supplement to your routine.
