South African Herb Rooibosch

What do you about th herb rooibos? Please let me know because my daughter who took this is having blood from her bowels and also her boss who also took it.

I have not heard of any negative effects from rooibosch tea. It is possible that the herb that your daughter and her boss took was contaminated.
Rooibosch tea is sometimes recommended as a substitute for black tea, because it contains no caffeine and it is low in tannins. Medicinally, it has digestive, antispasmodic and anti-histamine actions.
