Annique Theron is known as the mother of rooibos.
The housewife who later received an honorary doctorate may not have discovered the leaves but she made the connection between the tea and its medicinal properties.
Adele du Toit, who does the marketing for Annique, a Theron's company, says Theron, who died at the age of 85 last year, made the link when her daughter Lorinda was a rather ill baby back in 1968.
"Her fourth child was 14 months old and wouldn't stop crying. She was also intolerant of her mother's breast milk. To stop the wailing child Theron gave her the tea leaves that were brewing on the stove.
