What is Umckaloabo Plant Extract?

The usable part of Umckaloabo is the root. Active constituents are thought to be coumarins; hydrolysable tannins such as catechin, gallocatechin, gallic acid and other polyphenols; and proanthocyanidins. For bronchitis and other respiratory disorders, Umckaloabo is believed to have antimicrobial and immunostimulatory effects. Umckaloabo is used orally for treating respiratory infections such as bronchitis, pharyngitis, the common cold, tonsilitis, sinusitis, pharyngitis, and tonsillopharyngitis. It is also used for tuberculosis, herpes, gonorrhea, diarrhea, and dysentery.

Diseases and Conditions

Umckaloabo is likely effective for bronchitis, and possibly effective for tonsillopharyngitis. There is insufficient information on the effectiveness of Umckaloabo for the common cold and sinusitis, as well as its other uses.


Umckaloabo is likely safe when used orally in the short term. Not much is known about the safety of Umckaloabo when used orally in the long term.

Children may safely use Umckaloabo orally under the supervision of a physician.

There is insufficient information on the safety of Umckaloabo for pregnant and breastfeeding women, so it is best to avoid.

The correct dosage of any supplement requires a comprehensive analysis of many factors including your age, sex, health conditions, DNA, andlifestyle.

Thirty drops of a specific extract (EPs 7630®, Schwabe GmBh, Germany) three times daily for ten days has also been used for various respiratory tract conditions. For acute bronchitis, thirty drops of EPs 7630® solution (four and one-half milliliters total over three doses) (Umckaloabo, EPs 7630®, Schwabe GmBh, Germany), three times daily for seven to fourteen days has been used.
