A scratchy throat? You may want to dilute the tea down some more and see if that helps. I know the Memory formula of Dr. Christopher's gave me a scratchy throat the first time I drank it. I diluted it more and didn't have the same problem next time. With all herbs you always want to beaware of throat reactions. There is a muscle in the throat that will contract if it feels threatened by a bad food or one it does not recognise as a friendly. If this happens you wnat to stop that food or herb and if consumed again just try a little amount and make sure there is no reaction.
The red clover tera combination known as a blood cleansing formula used by Sitting Bull, Hary Hoxey, and Dr. John R. Christopher was at one time considered this nations number 1 anti cancer formula, so YES, this is an extremely powerful herbal formula and maybe you only want to take teaspoons full at one time, it is not a tea that can be drank like a can of pop. I myself do like one of the herbs in it because of the strong taste, but others such as the Amish LOVE this taste.
You have to remember Dr. Christopher used about 200 very friendly herbs in his practice that he considered safe even in high doses, but these are still very powerful herbs, especially to people that have not been grown up on herbal teas.
I do get behind, like I am now, the factory is working 6 days per week 10 and 12 hour shifts and that makes a mess of trying to keep up with the herbal hobby. I do miss many questions and glad to see others answer these for me.
