So impressed with the result after just 40 minutes my deep chesty cough which was getting worse by the day, is better by more than 90%. I tried a few other IC's for colds and flu but found this one worked for me. I used the Hummer directly on my chest through clothes. Thank you for this incredible healing aid, I am quite new to this method but feel really encouraged I now have a tool for ultimate healing and I have been in the holistic healing space for 30 years both as a practitioner and recipient.
