I have used Sinus buster, along with a "Thieves" type blend and other essential oils combined with jojoba on sinus areas, feet, neck, chest, etc. in a roller ball daily, since the early reports of Covid.
It worked very well, never got sick. Until tested positive and had bad cold and sore throat type symptoms in October of 2022, along with total lack of energy. Had excessive pain in cheekbone area of my face. My sister made me a roller ball of AIRWAY and carrier oil to try. Used it on all bones of my face, many times a day. Also, used on chest and back and inhaled, as recommended in Camp Wander's description of the product. For some reason, the ingredients in AIRWAY was what my body needed. Within moments, the pain in my cheekbones, especially near my nose - WAS GONE! Thank you so very much Camp Wander! I have now added it to my regimen.
