Lan adds that blending is sometimes essential. Every Morning Green Tea, a bottled tea beverage that claims to promote health and weight loss, was removed from store shelves after it was found to have insufficient tannins (polyphenols purported to have astringent, anti-inflammatory, and detoxifying effects, and to promote digestion).
藍芳仁指出，拼配有時還是必須的，如強調健康瘦身的市售瓶裝茶「每朝健康綠茶」，曾因被驗出「茶單寧」（即茶多酚，具收斂、消炎、解毒、幫助消化等功能）不足，被要求下架。
