Hi @alexgoldman2 the tea is called Shifa Tea which can be purchased through amazon. I followed the member’s directions to make a concentrated tea. I did that the first couple of times but have decided now to try the directions on the bag for a hot cup of tea. For the concentrated version: Add 1/2 the bag of tea to a quart of boiling water. Let steep for an hour. Save the tea in the refrigerator. Put a few ounces in a cup and add hot water for a hot cup of tea to sip on. Since I only needed 1-2 cups per month, I chose to freeze it instead in an ice cube tray. To make iced tea I would take out a couple of pieces and add a little water to sip on slowly. When I sipped on the tea as soon as I felt the headache coming on I had better luck. The headache would go away. The tea seemed to decrease the intensity of the headache the longer I waited. I will be happy to answer more questions. Best of luck. I hope it works just as well for you or even better.Toni
