Yarrow is a very valuable, traditional medicinal herb, with much scientific evidence of use in alternative medicine as an antiseptic, antispasmodic, astringent, carminative, diaphoretic, digestive, emmenagogue, stimulant, and tonics, vasodilator and vulnerary. The main constituents are volatile oils including linalool, camphor, sabinene, and chamazulene, sesquiterpene lctones, flavanoids, alkaloids including achilleine, polyacetylenes, triterpenes, salicylic acid, coumarins, and tannins which prove these uses in alternative medicine to be effective. Extracts of yarrow exhibit antibiotic activity and may also act as anti-neoplastic drugs. Yarrow is used against colds, cramps, fevers, kidney disorders, toothaches, skin irritations, and hemorrhages, and to regulate menses, stimulate the flow of bile, and purify the blood. My clients says this is a highly energetic hydrosol, helpful in spiritual healing work, that it provides mental calmness and helps one find peace. It is also recommended for cleansing the aura and cleansing crystals. It has recently come to my attention that Yarrow hydrosol is almost a miracle cure for any sort of itching skin condition. I use it on my pets, who seem to suffer a variety of itchy pink skin on their under bellies. It almost instantly soothes the itch of insect bites, eczema, poison ivy, sunburn a wonderfully effective skin soother. I've heard that the hydrosol, used as a compress or as the water phase of a lotion is effective in treating both psoriasis and eczema, soothing the itch, and calming inflammation, and assisting the basal cells of the skin in healing. While we make no medical claims, one can look at the phytochemical profile of yarrow hydrosol to understand where the traits emerge.
