Pelargonium sidoides (Umckaloabo)

Tier 2 — promising · Acute bronchitis · Cold · Respiratory

A South African plant extract with strong Cochrane-level evidence for acute bronchitis. The Timmer et al. 2013 Cochrane review (8 trials) found it significantly reduces symptom severity and duration of acute bronchitis and the common cold compared to placebo. Works best when started within the first 48 hours of symptoms. Generally well tolerated for short-term use of 7 to 10 days. Not for daily prevention, only acute illness.

Dose: EPs 7630 extract: 30 drops × 3 daily or 20 mg tablets × 3 daily for 7–10 days at symptom onset
