Bloukanna
Sutherlandia microphylla
Long before it found its way into wellness shops, this small silvery shrub was a household standby for the Khoikhoi and Nama peoples of the arid Northern Cape, who reached for it during almost any serious illness, fever, or long convalescence. Its Afrikaans name, kankerbos, means cancer bush, but it was traditionally given for a whole range of wasting conditions, low appetite, and general depletion, not for cancer specifically. Traveling farmers and missionaries later adopted it too, brewing the bitter leaves into a tonic tea meant to steady the body and lift a person's spirits during hard, dry seasons. Over generations it earned a quiet reputation as the herb you kept in the cupboard for whenever someone in the household was simply not themselves.
