"Thank you," the doctor said. "Once the chronic mucus is scrubbed away from the lung surfaces, then we can treat the membranes directly. There is membrane damage in your lungs, of course, deep cellular damage, but we cannot get to the damaged surfaces until the mucus is removed." He looked at Alex seriously, over his glasses. "Your chronic mucus is full of many contaminations, you know! Years of bad gases and particles you have inhaled. Environmental pollutions, allergic pollens, smoke particles, virus, and bacteria. They have all adhered to the chronic mucus. When your lungs are scrubbed clean with the enema, the lungs will be as the lungs of a newborn child!" He smiled.
