Vaccination can help protect you from the flu, as can frequent handwashing. And over-the-counter products can soothe cold and flu symptoms. But natural products can also help. ‘A combination of zinc and vitamin C can be helpful with cold and flu symptoms if you take them as soon as you start feeling ill,’ says Marianne Trevorrow, a naturopathic physician in Victoria, and director of the British Columbia Naturopathic Association. Some types of ginseng safely boost immunity for a preventive effect, as do vitamin C and echinacea. Saline irrigation’e.g., HydraSense Congestion Relief’helps decongest nasal passages.
Examples: A. Vogel Echinaforce Sore Throat Spray; Cold-Fx; HydraSense Congestion Relief; Jamieson Flu-Shield; Nature’s Harmony Zinc Lozenges with Vitamin C and Echinacea; Sisu Cold & Flu Rescue with Ester-C
