Safety & Contraindications
Class 2d. Fermented black tea not recommended for excess or long-term use. In excess can cause GI distress and nervous irritability. Caffeine syndrome in overindulgence, as with coffee, etc.. All things in moderation. One woman who consumed the equivalent of 65 g tea leaves/day for 5 years exhibited liver dysfunction. Ascites and splenomegaly resolved after tea was discontinued. Pedersen, who does not cover conventional tea, says that peppermint leaf contains much astringent tannin, which can damage the liver and intestine with prolonged use. Since the more widely used tea often contains twice as much tannin as peppermint, this recommendation should be doubly pertinent under tea, or maybe we should call these tannins by the more attractive names “OPCs, polyphenols, and pycnogenols” and declare them useful antioxidant good guys instead of hepatotoxic bad guys. Regarding caffeine, “Pregnant women should under no circumstances exceed a dosage of 300 mg/day. Infants whose nursing mothers consume beverage containing caffeine could suffer from sleep disorders”.
