1. Direct tumor injection (such as breast tumor): 1-10 injections as required; needle aspiration; liquification increases as the concentration of ozone increases; sometimes the installation of a continuous drain is required, sometimes just a poultice 2. Vagina, uterus: catheter administration with humidification; endometritis requires insertion of catheter into the cervical os. 3. Ear: for infections; 5 minutes per ear with humidification. 4. Direct intravenous injection: into the portal (rectal) vein for cancer (especially liver cancer) and hepatitis; it is suggested to use EDTA type chelation as well. 5. Autohemotherapy: syringe or bottle. 6. Nasal inhalation: 20 ug./ml. through 2" olive oil for 15 minutes twice daily. 7. Rectal insufflation: about 500 ml. in one minute spurts to use retroperistalsis to prevent gas pains. Slow continuous sdministration also satisfactory; humidification required. 8. Hyperbaric: 10 ug./cc. ozone at pressure of 45' of water - 30-35 p.s.i.. 9. The potency of any medicine is greatly increased when taken in conjuction with ozone therapy, eg. aspirin 100 times; chemotherapy 10 times. 10. Hydrogen peroxide injection: mixed results; it is suggested to keep amounts and concentration low - .0375%. 11. Ozonated steam cabinet suggested as a good method of treating lymph system. 12. External limb bagging.
