A lot of people are reporting having a good success rate with
LUFFA COMPLEX, it's a herbal remedy made by Vogel (formerly Bioforce). I started using it last week and already i can feel a slight difference, though as with most herbal remedies, they need to build up in your system. But its worth trying as there aren't any contraindications. Check out

Also Plantago for sinuses. You can combine them.
