What Are Catechins?
All tea comes from the Camellia sinensis plant.
The leaves of Camellia sinensis contain polyphenols that belong to the catechin family.
This helps prevent or delay cell damage and protect against inflammation.
White and green tea contain a higher concentration of catechins than other tea varieties.
Thats because the fermentation process used to make black or oolong tea causes the oxidization of catechins.
A study built upon previous research showed that tea can help lower blood pressure.
The researchers were looking for why tea has this effect.
Activating this protein causes the blood vessels to relax, creating better blood flow, which lowers blood pressure.
Green tea should be avoided or consumed with care during pregnancy and breastfeeding.
Black tea also contains caffeine.
People who are pregnant or breastfeeding should consume less caffeine, in accordance with their healthcare providers recommendations.

More research is needed to confirm its effect on blood pressure.
were effective in lowering both SBP and DBP.
While promising, more studies are needed to confirm this finding.
Hibiscus tea is caffeine free.

More information is needed to determine if this is considered more than a minor concern.

These treatments may not be enough to adequately lower blood pressure.
Medication may be needed as well.
