Samuel (11 years old) has suffered with ongoing sinus for the last year. The doctors say that it is the area we live in, it has a high pollen count and that it will just have to be managed with anti histamines. I have not been comfortable with continuously giving my child medication to keep the sinus under control. It was recommended that he take Winter Formula, which only has natural ingredients in it. Wow! after using the product for five months there has been a remarkable improvement. He no longer wakes up with a blocked nose and breathes so much better at night. This fabulous product has made such a difference to Samuel’s quality of life.
