This is a really good write up on stinging nettles, by a herbalist named Christina Stapley. Found here, it addresses food and drink uses, as well as some interesting folklore and historical data. I have personally used nettle tea for bladder and kidney health – it is very soothing to an irritated bladder. It is also recommended for arthritis and other bone-related maladies. As I have been drinking it I have noticed my hair seems thicker and healthier as well. Pretty impressive results for a “weed”. Christina’s website is www.heartsease-herb-books.com.
