I don't know if it boosts the immune system because I don't know the amount of Echinacea it contains, but it definitely has a nice taste.

After a contagious mononucleosis, I experienced continuous fatigue and this drink helped me a lot. I avoided continuous fevers.

Tasty. It reminds me a bit of the classic flavor, but with a pleasant variation. It has spicy notes and fills the mouth. I would recommend it.

I would say it is a light aromatic beverage, with a nice taste and sweetness (without added sugar). I might buy it again.

I don't know if the immune system actually helped because the amount of echinacea was small. However, it had a very nice taste... It can be consumed at night since it is caffeine free.
