I find dragons blood to be the most potent antimicrobial substance I have ever come across, I have cured stomach bugs 3 times with it already. I'm highly allergic to cats so when I stay in a house with cats, my sinuses get blocked and I get nasal infections and those Vicks First Defense sprays don't work very well at all so I got an idea. I filled a nasal spray with dilute dragons blood tincture.
I should warn you against making what in retrospect was a ridiculously silly mistake. I decide to dropper some pure tincture into my sinuses. I knew it was sting initially but for the whole night I had a sore throat and sinuses, the kinda sore throat where it hurts to swallow. I should have known a pure alcohol tincture would severely irritate the inner nasal cavity and throat lol. It worked though, the extreme itching I had stopped.
I should also mention though that every time I blow my nose, black stuff (dried dragons blood) comes out. I don't know if thats a problem or not (i.e. having a foreign substance remain in your nasal cavity for a long period of time) but it should be to a much lesser extent when the dragons blood is diluted.
