Pepper-Bark Tree
Warburgia salutaris
Among the Zulu, Swazi, Shangaan, and other southern African peoples, the pepper-bark tree has long been considered one of the most important trees in the medicine chest, its fiery, peppery bark chewed or brewed into a tea at the first sign of a cold, flu, sinus trouble, or sore throat. Traditional healers also turned to it for coughs, stomach cramps, and as a general warming tonic through the cold, damp months. Its reputation ran so deep that the tree became one of the most sought after in the region, bartered and carried far from where it grew. That same popularity, sadly, is what pushed it to the edge of survival in the wild, making today's cultivated trees all the more precious.

Traditional preparations.
Traditionally sipped warm at the very first sign of a cold, cough, or scratchy throat, valued for its intensely warming, peppery bite.
Traditionally, a small pinch (about 1/4 teaspoon) of dried, powdered bark is steeped in 250 ml of just-boiled water for 10 minutes, then strained and sipped slowly while warm.
The same mild infusion, cooled to a comfortable temperature, has traditionally been used as a gargle for a raw or irritated throat.
Prepare the tea as above, allow it to cool until comfortable, and gargle a small mouthful for 20 to 30 seconds before spitting out.
Safety.
This tree is critically endangered from overharvesting, so use only cultivated, nursery grown bark, never wild-harvested material. The bark is intensely hot and pungent and can irritate the mouth, throat, and stomach if used beyond small traditional amounts.
