When my sinus are inflamed I find this product does a nice job or keeping the inflammation down. Plus I'm a firm user of essential oils and this one uses those that are great for the sinuses. These oils are know to open up the sinuses and also have antimicrobial properties, win win.
This is a really good addition to my neti pot rinse. I add around a teaspoon of pure sea salt to boiled water and allow it to cool down. I then add two droppers of neti wash plus and it really helps when my nose is a bit stuffy or runny. I can't say if it is doing anything specifically but the ingredients are beneficial so I will keep using it.
