Quinsy. Um-qala. Gargles are used of hot infusions of Isi-duli, Mimosa, or bitter olive tree, etc.
Diphtheria. I have no record of this disease being recognised by the Kaffir as anything but sorethroat Umqala, if it occur at all.
Dyspepsia and Indigestion. I-dliso.
Believed to be caused by eating poisonous foods, and usually treated by emetics e.g. In-kamamasane (Euphorbia pugniformis) one [[77]]of the class of drugs known amongst the natives as Intsema, acting as a severe emetic and purge. The juice tapped from the living stem of these plants is collected in maize meal and made into a bolus to be swallowed; about half a drachm of the drug being taken at a time. As this is nearly as severe as croton oil, the action is easily to be understood and in a country and nation where at times great overfeeding and gorging is practiced, such a treatment is a valuable asset.
Another favourite purge is Um-gwali (Euclea lanceolata), the bark of the roots being used.
Colic. Uku kunywa or I-honya.
Treatment. a. The Powdered root of In-nyongwane, (Deconia anomala) is administered in cold water.
This plant is also put to a curious use by the Kaffir. When visiting a strange place he eats some of it, believing that if he gets poisoned food he will immediately vomit it.
b. The knobs from the roots of the in-dawa (Cyperus) are used, either chewed as they are or as an infusion of the powdered knob. It has an aromatic pungent taste. [[78]]
c. The powdered root of I-qwili (Alepidea amatymbica) is also used for colic or abdominal pain, a teaspoonful to a dose.
