Active Ingredient	Uses based on scientific evidence	Grade*
chamomile (matricaria recutita, chamaemelum nobile)	in early study, inhaling steam with chamomile extract has been reported to help common cold symptoms. further research is needed to confirm these results.	c
green tea (camellia sinensis)	in humans, preliminary date suggests that a specific formulation of green tea may help prevent cold and flu symptoms. further well-designed clinical trials are needed to confirm these results.	c
propolis	there is some evidence that propolis may help prevent infections with the virus that causes the common cold. propolis nasal sprays have been suggested as a treatment for runny nose, congestion, and fever in children with nose or throat infections. however, there is not enough clinical evidence to support this use of propolis.	c
vitamin c (ascorbic acid)	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 climates or under extraordinary conditions, including soldiers in sub-arctic exercises, skiers, and marathon runners, vitamin c significantly reduced the risk of developing colds by approximately 50%. this area merits more study and may be of particular interest to elite athletes or military personnel.	b
vitamin c (ascorbic acid)	numerous studies have examined the effects of starting vitamin c after the onset of cold symptoms. overall, no significant benefits have been observed. initial evidence from one study reports possible benefits with high doses of vitamin c taken at the onset of symptoms, but without additional evidence this remains indeterminate. at this time, the scientific evidence does not support this use of vitamin c.	d
zinc	there are conflicting results regarding the effect of zinc formulations in treating duration and severity of common cold symptoms. although zinc might be beneficial in the treatment of cold symptoms, more studies are needed to clarify which zinc formulations may be most effective, which rhinoviruses are affected by zinc, and if nasal sprays provide a useful alternative application route for zinc treatment. a recent study found no significant differences between zinc nasal spray and	c
