There is no reliable human evidence evaluating sorrel monotherapy as a treatment for bronchitis. However, it is an ingredient in the combination herbal product Sinupret, which also contains cowslip flower, European elderflower, gentian root and verbena. This proprietary formula has been used historically in Europe for the treatment of acute bronchitis and sinusitis. Although no studies have been conducted comparing the combination product to placebo, there is initial evidence from a comparison trial of various expectorants vs. Sinupret in the treatment of acute bronchitis. Additional evidence is necessary before a firm conclusion can be drawn regarding the use of sorrel or Sinupret in the management of bronchitis.Copyright 2007 Natural Standard, Inc. |
