>>>By the way, a few drops of the echinacea on the tongue kind of stung for a bit and then made the entire tongue numb. Is that what it should do?<<<
That's EXACTLY what it should do...the "number" the better!!
A 1" piece of Echinacea root chewed on for 5-10 minutes will "novacaine numb" your entire mouth for around 30 minutes...and that's what Native American's did commonly. There's no WAY we can do that with tincture, so she does NOT have to worry about it being "too much". What she needs to worry about is getting ENOUGH! :)
'Hope she's doing what she should be doing! :) Whatever we do 'naturally' is no where NEARLY as extreme as what they'll do if she has to go back into the horrorspital :(
