I wanna ask for the best cure for sinus and what if there is natural cure & the artificial one?

Natural sinus: sinus irrigation, netti pot, nasal rinse with saline can help as well. Many herbal remedies can assit in drainage and immune boosting

Xylitol: Xylitol is a natural sugar and breaks up biofilm in the body. That's where germs mulitply. It is found in a nasal spray called xlear (pronounced "clear") and in chewing gum called spry. Pleasant tasting too! Check w/doctor first to make sure you don't have a medical condition.
