It is noteworthy that Hildegard von Bingen (the famed German mystic and healer) mentioned 900 over years ago in her herb book Physica that anyone going under knife need to be protected by the herb yarrow.
Yarrow is an ‘anti-inflammatory’ herb and both cool and move the blood for wound healing. I often give either as a tea or a tincture to take prior and after a surgery to aid in wound healing. As the study shows, yarrow may be protective as it is a mild anti-inflammatory and possess wound healing properties not found in any drugs.
