Science
Mechanism of Action
PELARGONIUM SIDOIDES ADVENTITIOUS ROOT EXTRACT is rich in beneficial phytocompounds, including coumarins and various polyphenols like proanthocyanidins, gallic acid, catechin, and taxifolin. For the skin, its action is primarily through bacterial-balancing and potent antioxidant effects, preventing oxidation and deterioration of other ingredients. It provides comprehensive antimicrobial (both antibacterial and antifungal) properties, which can be bacteriostatic or bactericidal, and also exhibits an antiadhesive effect, hindering bacterial attachment to human cells. Furthermore, it modulates the immune response by influencing gene expression, leading to increased cytokine production (IL-1, IL-2, IL-6, IL-10, TNF-α, and IFN) and boosting cellular defense mechanisms like phagocytosis. This extract also supports tissue integrity and strengthens the epithelial barrier function.

Key findings
- 01 Clinical trials for an internal proprietary extract (EPs 7630) have demonstrated significant efficacy in treating acute respiratory tract infections. For instance, a 60 mg daily dose showed a 90.0% success rate in children with acute tonsillopharyngitis compared to 44.7% with placebo (p<0.001).
- 02 In adults with acute bronchitis, 30 drops three times daily of EPs 7630 for 7 days significantly reduced symptom severity and shortened the duration of working inability (p < 0.0001 for Bronchitis Severity Score decrease on day 7).
- 03 EPs 7630 was also found effective for the common cold, with 51% of patients showing 'major improvement' versus 12% with placebo. It is crucial to note that these studies pertain to internal consumption, and specific topical clinical efficacy data for skin applications is not provided.

Safety
Safety Profile
A proprietary extract of Pelargonium sidoides (EPs 7630) has been extensively studied in clinical trials, predominantly for internal use, and is generally considered safe and well-tolerated. Reported adverse events are rare and typically mild, including gastrointestinal discomfort, mild bleeding, and allergic reactions (primarily for internal consumption). The European Medicines Agency (EMA) has approved EPs® 7630. Allergic skin reactions have been rarely noted, indicating a low risk for topical applications.
