Benifuuki green tea (Also written sometimes as Benifuki) is a type of green tea that is booming in Japan due to being good for relieving allergies such as seasonal allergies, cedar allergies, hay fever. Study has also shown that benifuki is good for MCAD (Mast Cell Activation Syndrome). Methylated Catechins are generally known for bitterness and astringency; however, the Arahataen research team created a specific type of natural dirt to grow Benifuuki, which allows more Methylated Catechins to remain in the tea yet retain aroma and flavor by reducing the bitterness and astringency.
