Pelargonium sidoides (EPs 7630) 1X - the main ingredient in Umcka ColdCare - works with the immune system to help support the body's own natural defense mechanisms. That means you're getting a medicine that works safely with your body - not against it. Clinically proven to speed recovery. Umcka goes beyond symptom relief and actually helps you recover faster - which means you can get back to life faster, too. In fact, studies show that adults with acute bronchial irritations were able to return to work nearly two days earlier with EPs 7630. You can feel confident knowing that the EPs 7630 found within Umcka has been widely studied by various clinical organizations in the treatment of the common cold, bronchial irritations and other upper respiratory concerns.
