Cancer Bush
Sutherlandia frutescens
For generations, Khoikhoi and San healers turned to this silvery-leaved shrub as an all-purpose tonic, brewing its leaves into a bitter tea for fevers, coughs, and the aches of a hard season. Cape Dutch settlers adopted the plant too, giving it the Afrikaans name kankerbos, or cancer bush, a term that in old colonial usage referred broadly to internal wasting complaints and stubborn sores rather than cancer as we define it today. Across Zulu, Xhosa, and Sotho traditions alike, it has long been valued as a restorative for those recovering from illness or exhaustion, taken to steady the nerves, settle the stomach, and help the body find its footing again. It remains one of the most widely used traditional tonics in South Africa, still gathered and shared as a bitter, bracing cup of comfort.

Traditional preparations.
A bitter, grassy infusion traditionally sipped as a fortifying tonic during times of stress, fatigue, or seasonal illness.
Traditionally, a tea is made by steeping 1 teaspoon of the dried leaf in 250 ml of just-boiled water for 8 to 10 minutes, then straining. A little honey softens the bitterness. This was traditionally taken once daily, not as a regular, long-term habit.
Safety.
Cancer bush is traditionally avoided during pregnancy and breastfeeding, and may interact with immunosuppressant medications or antiretroviral therapy. It isn't meant for large doses or long uninterrupted use.
