No its not about use inside nasal. I take the drops regularly and stop my sinus symptoms.
I was with sinus for a long time every winter, and take the regular medicine to inflammatory and antibiotics.
I got contact with this homeopathy but never used seriously. Then I was living in Germany for some months,
and get a really strong pain with sinus. Well, I go to a Doctor, and again prescribe the same.
Oh, antibiotics make me down, I was living alone with a great pain, but I didn't want get down by antibiotics.
Then I give a try to Homeopathy that was with me, take with regularity prescribe for crises and when get better
take 3 times a day. I take for one and a half year, since that I never more get sinus problem for more than a decade.
Works for me. May be because my will and my mind my body reacts.
I stay with results!
If could give you one and you could make a experiment with someone else.
I told, after this good results, with this specific product, from a specific source, with many friends
that use their self and with his/her sons and daughters, I confirm that until now are working.
