Hello, Radko, yes, it is possible. If we want to apply Streptokill to the nose, we recommend diluting it first, because the application of undiluted Streptokill to the nose is too burning for most people. First, spray 1 part of Streptokill (20 sprays = approx. 2 ml) into a small glass, then add 6 parts of water (teaspoon = approx. 12 ml). Lie on your back and pour the diluted Streptokill into the nostrils (the easiest way is to use a syringe or if you pour the diluted Streptokill into an empty bottle from the already used Streptokill and apply it to the nose using an oral applicator. If you tolerate the diluted Streptokill well in the nose, you can for the next application, try injecting less diluted or undiluted Streptokill directly into the nostril using an applicator. Especially undiluted Streptokill can cause a very strong burning sensation, which, however, subsides after a while. I wish you a speedy recovery, Pavel Soukup STREPTOkill.cz
