When I ran out of non-caffeinated tea earlier this winter, I took the jar out of hiding, put a teaspoon of the mix in the bottom of a tea mug, and poured boiling hot water over it. Wow - this is powerful warming tea that also cuts mucus. In fact, be careful with it - it doesn't burn your tongue, but will make your body hot. I've had no trouble with acid reflux with this tea, and several of the spices listed are considered digestive aids; in ayurvedic terms, the spices lift your pitta, or fire, and that's what ultimately enables digestion. Turmeric is also an anti-inflamatory, so perhaps it mollifies the more pungent seeds in my system.
Here are the spices - you can find most of them in bulk at Whole Foods, or visit an Indian grocery store.
These are powerful spices, so treat them with the respect you would treat medicine. Manjuali Devi, the master chef and teacher at Kalachandji's told the class that men should be careful with the amounts of these pungent spices that they consume - they can raise body temperature higher than men's sperm can stand and therefore effect potency.
