Rooibos For Type O?


Rooibos tea is a herbal tea well known in South Africa. Can it be used by type O blood?


Yes, I though so highly of its health properties for type O that I included it in the 'Sip Right 4 Your Type' tea formulas for type O that we developed with The Republic of Tea. In particular I find Rooibos effective in 'tempering' the slightly over-enthusiastic type O immune system, leading to diminished allergies and autoiimmune problems.

Rooibos has significant anti-HIV activity (1) and appears to be somewhat protective against UV damage,(2) probably because of its anti-oxidant activity. The anti-oxidant activity in the plant also seems to suppress the age-related accumulation of lipid peroxides in th brain, at least in test animals. (3)

Rooibos has no caffiene, so it appears to be a good substitute in situations where the caffiene contain in green tea may prohibit its use. Like green tea, rooibos inhbits polyamine formation by blocking the enzyme ornithine decarboxlase. (4)

The Ask Dr. D'Adamo internet advice column ran from 1996 to 2009, at which time Dr. D'Adamo's teaching and programming responsibilities no longer allowed him to devote time and resources to directly answering visitor questions. However we've recently reorganized this treasure-trove of material and made it again available to his readership. He occasionally posts new entries. These are marked with a NEW tag.
