The Graedon's are far from shamans...a PhD pharmacologist and a medical anthropologist. I enjoyed a special talk they gave as part of an Herbfest. Thyme is good for colds too.....add to chicken broth or make a tea. Ginger, elderberry flower or mint tea too. Can use those herbs any day of the lunar cycle

And as crazy as they sound, perfectly normal people in my neighborhood say the Vicks on the feet for cough and the bar of soap under the sheet for muscle cramps really works. Why they are called home remedies
