Hypericum a must for the first aid kit

E.B. Nash wrote about the remedy:

"Hypericum is the remedy "par excellence" for wounded or 

injured nerves; from simple punctures from nails, splinters,

pins, rat bites, etc., to severe concussions of the spine and 

brain, and especially to parts rich in centient nerves. It is to 

this kind of injuries what Arnica, Hamamelis, Ruta, etc., are

to bruises, and Calendula to lacerated muscular tissue, and,

Staphisagria to cuts with sharp instruments."
