Congrats to Simon who correctly named Horsetail as the Mystery Herb. My little herb handbook, Oregano is going out to him or he might want this book if he doesn't already have it.
Horsetail- Simon gathers it and dries it to a powder for some of the best silica locally grown.
I used horsetail in hair rinses and to soak my nails to strengthen them. I have even made a tea from young horsetail gathered before the end of May.
This is the little spore head - this was taken Sunday May 3.
