South African Geranium for COPD
A 2013 study found that an extract from the roots of South African geranium (Pelargonium sidoides) may prolong the time to exacerbation for people with chronic obstructive pulmonary disease (COPD). The extract was given daily, in addition to standard medical therapy, for 24 weeks and compared to a placebo group. Other studies found that a similar extract may improve symptoms and reduce duration of symptoms in children and adults with upper respiratory infections. South African geranium may cause digestive or other side effects.
