I so wish I could send you a couple of my favorites. One is a houseplant and nobody knows it's real name. I got a slip from someone and they called it a vicks plant. I boil the leaves and it's wonderful with the start to recovery being the next morning. The other is an indian remedy and no known name as well. The Blackfoot call it rat root and it is the root of some tree found near bever dams. It's a natural throat treatment. Very foul tasting and not to be eaten, only chewed or held in the mouth for as long as you can. The truly tough can chew a piece the size of a grain of barley for only a second or two but it's never in my life failed me. If there was any possible way that I could have gotten them across the border, I'd have gladly done it for her but without no known identities, it would never make it across. Failing that, I'd recomend tea and natural honey and as much water as she can drink.
