In two double-blind, placebo-controlled studies enrolling a total of about 300 young men, this standardized combination proved more effective than placebo in resolving sinus symptoms.1 After two weeks of treatment, about 2/3 of the participants using the herb described their infection as cured, while only about 1/3 of those taking placebo described themselves as cured. This herbal combination is hypothesized to work by thinning mucous and perhaps also by enhancing the immune response to infection.
