Sage: Sage mouthwashes and gargles have been approved for use against sore throat in Germany by the German Commission E. Additional study is needed comparing sage to standard therapies for acute pharyngitis (inflammation of the pharnyx). Avoid if allergic or hypersensitive to sage, its constituents, or to members of the Lamiaceae family. Use cautiously with hypertension (high blood pressure). Use the essential oil or tinctures cautiously in patients with epilepsy. Avoid with previous anaphylactic reactions to sage species, their constituents, or to members of the Lamiaceae family. Avoid if pregnant or breastfeeding.
Vitamin C: Vitamin C, or ascorbic acid, is a water-soluble vitamin, which is necessary in the body to form collagen in bones, cartilage, muscle, and blood vessels, and aids in the absorption of iron. Dietary sources of vitamin C include fruits and vegetables, particularly citrus fruits, such as oranges. Scientific studies generally suggest that vitamin C does not prevent the onset of cold symptoms. However, in a subset of studies in people living in extreme circumstances, including soldiers in sub-arctic exercises, skiers, and marathon runners, significant reductions in the risk of developing colds by approximately 50% have been reported. Additional study is needed to better determine the effectiveness of vitamin C for common cold prevention in extreme environments. Avoid if allergic or sensitive to vitamin C product ingredients. Vitamin C is generally considered safe in amounts found in foods. Vitamin C supplements are also generally considered safe in most individuals if taken in recommended doses. Large doses (greater than 2 grams) may cause diarrhea and gastrointestinal upset. Avoid high doses of vitamin C with glucose 6-phosphate dehydrogenase deficiency, kidney disorders or stones, cirrhosis (inflammation of the liver), gout, or paroxysmal nocturnal hemoglobinuria (bleeding disorder). Vitamin C intake from food is generally considered safe if pregnant or breastfeeding. It is not clear if vitamin C supplements in doses higher than Dietary Reference Intake recommendations are safe for pregnant or breastfeeding women. Vitamin C is naturally found in breast milk.
