Excerpt from the May Day holiday e-book:
Sweet woodruff (galium odoratum) is one of my favorite plants. It is a low-lying ground cover with narrow dark-green leaves that grow in whorls around a central stem. It blooms around the first of May: small white flowers with four petals. Woodruff grows best in shade; mine is happy in a part of my garden which is rather moist. In Germany, it is called Waldmeister (master of the forest).
Woodruff does not have a strong fragrance until picked. But once dried, it develops a wonderful sweet aroma, a mixture of hay and vanilla. The scent comes from coumarin, a fragrant chemical also found in melilot and tonka beans. Coumarin is also an anti-coagulant and is used in blood-thinning medication.
Because of the presence of coumarin, the FDA only permits the use of sweet woodruff in alcoholic beverages (does that make sense?). Apparently large quantities have been known to cause vomiting and dizziness. It is probably best not to consume woodruff if pregnant or taking anti-coagulants.
Folk remedies call for the application of woodruff to fresh wounds; Rose speculates this would have kept the blood from clotting and prevent infection. Sweet woodruff was also made into a medicinal tea which soothed the stomach. It was recommended for heart and liver problems. The dried herb is wonderful for scenting potpourris, can be stuffed into sachets and tucked between linens to scent them. It is used to flavor May wine but it also has a reputation for provoking lechery, which may be another reason for its association with May Day.
Woodruff can be grown easily from starts. Mine came from my mentor and friend Helen Farias. Just dig up a little clump, roots and all. Plant it where it will get shade and its roots will stay moist. The plant spreads rapidly but is not invasive.
During my experiments with capturing the scent of plants, I was most successful with sweet woodruff. I let it sit in jojoba oil for about a week and now the oil is delicately flavored with that dry hay/tobacco/vanilla scent that I associate with lying in the grass at midsummer.
