Nature’s Sunshine Products: When in an unfriendly environment, I take Silver Shield. Silver Shield comes in liquid (Silver Shield w/ Aqua Sol) that I can add to water or healthful beverage. In unhealthy breathing environments, to protect my respiratory system, I use Silver Shield Rescue Gel within my nostrils. I find it a great opportunity to protect what comes through the nasal system to better protect the body.
