Umckaloabo is most often used for


Pelargonium sidoides, commonly known as African geranium, is a medicinal herb. It is also sold under the brand names Kaloban and Umckaloabo as a plant-derived pharmaceutical.

Pelargonium sidoides is very effective for treating acute bronchitis. It increases the body’s natural healing rate. Studies have found that 40-60% of patients suffering from acute bronchitis fully resolve their symptoms within a week of Pelargonium sidoides supplementation. Some people reported experiencing benefits after just two to three days. People that are not cured after a week still experience benefits from Pelargonium sidoides supplementation, since it can treat the symptoms associated with bronchitis, including headache, fever, fatigue, cough, chest pain while coughing, sputum in the lungs, rhonchi, and nasal dripping.

Preliminary evidence suggests Pelargonium sidoides can reduce the duration of the common cold, while treating symptoms. It may also provide benefits for people suffering from lung disorders, by alleviating flare-ups in symptoms.

Pelargonium sidoides has anti-infective properties. It prevents bacteria from adhering to cells, helps fight viruses and stimulates the immune system to hunt down invaders.

Pelargonium sidoides may be able to fight Helicobacter pylori infection, which is the stomach bacteria that causes stomach ulcers. Pelargonium sidoides may also reduce the replication of the herpes simplex virus.

Dosage information

To supplement Pelargonium sidoides, take the patented extract EPS7630, which is an 11% ethanolic root extract.

The extract is concentrated to 1:8-10, so there is some variability with the recommended dosages. To supplement the extract, take 4.5mL of the tincture (30 drops) or 30 mg of the capsules. Dosages vary by age:

• 10 drops (1.5mL) or 10mg of EPs7630 is taken thrice daily before meals for those under six years of age • 20 drops (3.0mL) or 20mg of EPs7630 is taken thrice daily before meals for those between six and twelve • 30 drops (4.5mL) or 30mg of EPs7630 is taken thrice daily before meals for those above twelve years of age

While the vast majority of studies have used EPs7630 specifically, any hydroalcoholic (water and ethanol) extraction equal to 800mg of the plant can be used as an alternative.
