I learned about this tea a few months ago and I have become fascinated with it since I suffer from allergies a LOT, and I absolutely hate taking medicine for it. Normally I see it in powdered form but this was my first time seeing it in full leaf form. The tea is pretty normal tasting for a green tea, but it is quite expensive for what you get. I think I prefer the powder because I can control the amount and it’s easier to carry in my purse. I almost think it’s better to take the powder since you’d be ingesting the whole leaf, and isn’t that what you want to do if you want to fight allergies? Either way, this is a good alternative if you’re not a fan of powder or prefer loose leaf.
I can’t really comment on the allergy relief because it’s not really an instant thing. You have to take it several months ahead of time before hay fever season starts. I plan to do that next year to see if it helps. Apparently it’s a big thing in Japan.
