I have seen many claims that ecological negative ions can cure asthma. I don't know if it's really useful. What does ecological negative ion mean?

For the treatment of asthma, negative ion therapy is really effective. 32 patients with bronchial asthma in the Affiliated Hospital of Taishan Medical College were selected for clinical observation. The results show that most patients feel fresh air and comfortable when using air negative ions to treat bronchial asthma. Clinical examination shows that asthma is relieved, wheezing is reduced, breathing and heart rate are slowed down, and many lung functions of asthma patients are improved. The title of the literature report is "Observation on the effect of air negative ions on air disinfection and bronchial asthma treatment in respiratory ward".

Ecological negative ions are small particles of negative oxygen ions, also called light ions or small ions. They are equivalent to air negative ions in nature, and some data call them ecological negative ions. It has the characteristics of long migration distance and high activity. Medical research shows that it is small particle size negative ions that have medical and health care effects on human body. Because only negative ions with small particle size can easily penetrate the blood-brain barrier of human body and exert their biological effects. Clinical studies have found that negative oxygen ions can effectively strengthen the ciliary movement of tracheal mucosa, affect the respiratory enzyme activity of epithelial villi, improve alveolar secretion function and lung ventilation and ventilation function, relieve bronchospasm, increase vital capacity, adjust respiratory frequency and relieve cough. Negative ions can also promote the regeneration of nasal mucosa epithelial cells and restore the secretion function of mucosa. It has a good curative effect on asthma, tracheitis, pertussis in children and other diseases.

The technology of artificially generating small particle size negative oxygen ions is two patented technologies: negative ion converter technology and nano fullerene negative ion releaser technology. Negative ion converter technology can produce ecological negative oxygen ions with small particle size, high activity and long migration distance, while nano-fullerene negative ion releaser technology is an electrocatalyst material made of fullerene, which is a superconducting material with almost zero resistance. When ions pass through this material, it will produce strong vibration benefits, which is very conducive to the free precipitation of ions, so there is no need for strong current like ordinary carbon fiber materials. Only a relatively weak current is needed to release large dose, high purity, high activity and small particle size negative oxygen ions.
