Hi, Liza! I was hoping you can help answer a question for me! The Materia Medica monograph on Verbascum mentions that it helps to reduce irritation and inflammation for COPD. Then, in the Combinations section, it says “Restoring lung tissue” and has Oat and Horesetail as good herbs to combine. Do you know what part of the oats and perhaps a sample formulation for a daily cup of tea for someone with COPD? Thank you!
