Our Philosophy
Common Sense Medicine is built on the belief that supporting the body's own defenses — rather than overriding them — leads to better outcomes, lower costs, and healthier communities. Read the foundational essay →
The nose is the gateway to respiratory health. Xylitol-based nasal sprays assist the body's natural nasopharyngeal washing, reduce bacterial colonization, and help prevent allergies, asthma, sinus infections, and ear infections.
Prevention is dramatically less expensive than treatment. Empowering patients with simple, evidence-based tools — like regular nasal hygiene — reduces healthcare costs while placing responsibility for daily health back in patients' hands.
Modern medicine often suppresses the very defenses that protect us. Defense Medicine honors symptoms as the body's adaptive responses and supports physiological systems — rather than hobbling them with drugs that treat effects, not causes.

About
Dr. Lon Jones is a board-certified osteopathic family physician with over four decades of experience practicing in rural New Mexico. He is the founder of Common Sense Medicine, a 501(c)(3) nonprofit foundation dedicated to research on foods with drug-like effects and the paradigm of defense medicine.
After reading about Finnish research showing xylitol chewing gum could prevent recurrent ear infections, Dr. Jones developed a xylitol-based nasal spray to help his granddaughter — an experiment that grew into clinical practice results showing over 95% reduction in infections, and ultimately the creation of Xlear nasal spray.
Together with his colleague and wife, Jerry Bozeman, Dr. Jones continues to promote defense medicine, fund research, and educate patients and physicians on the power of supporting — rather than suppressing — the body's natural defenses.
