Thanks for the tip. I'm not a professional and stating this from personal experience from myself and my friends who have contracted the virus, and utilized this method. I personally never got tested for covid but when I felt symptoms for a week, I utilized this remedy and I felt completely healthy. One of my lady friend did confirm to have covid and utilized this method, stated she felt better, but still went to the hospital just as safety. Thankfully she was released after 1 week and is now negative for covid Also, to my knowledge, the covid virus live, reproduce and thrive in lower temperature areas, and the coldest areas in your body is the back of your nose (nasal cavity area), feet, and hands. Other flu viruses also live in this area so I tied 2 and 2 together. I also saw a few videos online spreading information about this remedy, but none are scientifically backed unfortunately. I can guarantee that it will help with cold symptoms like sore throat, runny nose, headache, etc... It's like a sauna on steroid haha. Thanks for the warm welcome also.
