I've been drinking rhodiola rosea tea recently. It smells like roses and tastes a bit astringent. I'm addicted to it. This was when I was traveling in the Tibetan plateau last time and had altitude sickness. My Tibetan landlord gave it to me and it helped me get better. I'm in love with it. Rhodiola rosea grows on the snowy mountains at an altitude of 4,000-5,000 meters. It's also very good for the body.
