I had some serrapeptase to fight my fibroids. I had been house bound with a bad cold since xmas. All the lemon and whisky was not helping to fight. Woke this morning with a heavy head, headache, nasal congestion. Well I upped my usual dose to two 30000units capsules before eating. Well within 2 hours the nasal congestion and inflamation is down and am breathing through both nostrils.the pressure and headache is reduced as well. Infact am breathing cold air with no pain as I go for some chicken bones for soup - have not been able to do so for 2 days.
