    Overview

    Dosage information

    Formulation

    Umckaloabo is most studied as an oral preparation (liquid drops, tablets, and syrups) of Pelargonium sidoides root extract. Liquid and tablet forms are typically cited in the current clinical evidence with dosage, frequency, and timing adjusted according to age and indication for use.[1][2][3][4][5][6][7][8][9]

    EPs7630 is a commonly studied standardized extract, which contains an ethanol (11% w/w) extract at a ratio of 1:8–10.[2][7][8][9]

    Range of dosages studied

    Dosages vary across studies and populations and depend on age and formulation. For adults, total daily doses ranged from 90 mg to 7.2 grams, and children’s dosages tended to range from 30 mg to 3.6 grams per day. The most typical regimen for drops, regardless of age, was 10 to 30 drops per dose, three times per day (equating to about 120–240 mg per day). Tablets were more often dosed between 30 and 90 mg per day. Duration of treatment and follow-up after the study lasted anywhere from 5 to 21 days, with 7 to 10 days being the most frequent duration.[1][2][3][4][5][6][7][8][9]

    Other Considerations

    The most consistently used formulation in research is the standardized extract of EPs7630.[2][7][8][9]
