Pelargonium sidoides

Though less well-known than some other herbal cold remedies, extracts derived from this plant have been shown to decrease the symptoms of acute bronchitis. One study, published in the journal Phytomedicine in 2003, examined 468 adults with acute bronchitis lasting less than two days who were given either placebo or an extract of the roots of Pelargonium sidoides; those in the latter group were told to take 30 drops three times a day for a week.

The treated patients saw quicker resolution of symptoms including pain during cough and fever, and were able to return to work in an average of 4.7 days (compared to 6.3 days for placebo).
