Making salve and tincture from Herbalist Lisa Zahn's site,http://herbalistlisazahn.blogspot.com/2008/07/yarrow-oil-salve-and-tincture-how-to.html
Harvest the herb just as in tincture-making but dry it for a day or so out of sunlight. Tear or cut the herb into one inch pieces and pack tightly into a jar, to the top. Fill the jar to the top with oil (cold pressed, organic olive, coconut or other oil). In a couple days, fill again to the top if some oil has soaked in. Keep a lid on the jar and let it sit on a plate in the sun for six weeks, no more. Some oil will seep out. Check for mold and scrape off as needed. After six weeks, decant the oil into a jar and squeeze any oil out of the herb material through cheesecloth. Thank the plant and compost it.
To make a salve, take a bit of beeswax (1/2 to 1 t.) and melt it on the stove. Take it off the heat, stir in the herbal oil and pour immediately into your salve container. It will set. Adjust beeswax amount to desired consistency and re-do if needed.
Edible use: Used to manufacture beer in Europe. Used in salads.
