Astragalus is proven to be effective in reducing asthma symptoms, including those that come along with respiratory tract infections and seasonal allergies. The anti-inflammatory effect of the herb reduces inflammation of the upper respiratory tract. It can also help improve narrowed airways that cause shortness of breathing and wheezing in people with asthma. In some studies, treatment with astragalus even prevents asthma recurrence.
