Just like to kick in here Yarrow is amazing. It is a styptic, a muscle relaxant, sedative, anti-inflammatory, anti-microbial, and aids in digestion.

A trick we use where I come from is making Woodsman Tea by harvesting a bunch of it and putting it in one of your canteens. At the end of the day the heat and motion from walking in the sun causes it to infuse the water. When you drink it your tired aching muscles relax and you can get a good night's sleep.
