Taxorest
Taxorest is a profoundly potent Cytomax natural peptide bioregulator, composed of highly targeted extractions from young bronchial mucosa. Regarded as the natural, full-spectrum biological twin to Bronchogen, it is a key component to aggressive respiratory restoration. Clinically favored for violently halting age-related chronic bronchitis, rapidly repairing airway damage from prolonged smoking, and drastically clearing deeply entrenched alveolar mucus.

Scientific Data
Mechanism of Action
Taxorest (A-19) is a Cytomax natural polypeptide extract from the bronchial mucosa of young calves, targeting human bronchial epithelial cells, Clara cells, and type II pneumocytes to restore age-silenced gene expression governing mucociliary clearance, surfactant synthesis, and bronchial anti-inflammatory signaling. The lungs undergo progressive structural aging: mucociliary clearance slows (reducing the ability to expel inhaled particles), alveolar surface area declines by 4 m² per decade after age 30, and type II pneumocyte reserve capacity for surfactant production diminishes, contributing to declining FEV1 and increased respiratory infection susceptibility.
Taxorest delivers short peptide signals (<10 kDa) from bovine bronchial tissue. These peptides penetrate bronchial cell nuclei to reactivate transcription of genes encoding: CFTR (cystic fibrosis transmembrane conductance regulator, critical for airway surface liquid homeostasis), MUC5AC and MUC5B (airway mucins essential for the gel-on-brush mucociliary defense system), surfactant protein D (SP-D, which neutralizes inhaled pathogens), and IL-10 (bronchial anti-inflammatory cytokine). This is a tissue restoration mechanism — not a bronchodilator or anti-inflammatory drug.
In Khavinson's protocols, Taxorest (A-19, bronchial) is often paired with Chelohart (A-14, heart) and Ventfort (A-3, blood vessels) for the cardiovascular-pulmonary system bundle, since pulmonary vascular resistance and gas exchange efficiency are directly coupled to cardiac output demands.
