Sodium ascorbate nasal spray

I read that a few people had success with adding sodium ascorbate to nasal spray for sinusitis. I tried some and it works almost like an antihistamine, it seems this would be a good alternative to cortisone nasal sprays. Apparently much more vitamin c is absorbed into the blood stream through the sinuses. I'm wondering would this be a worthy alternative to liposomal vitamin c?
