DESCRIPTION:
Sweet Woodruff is a low-growing perennial herb reaching 15–30 cm in height. It features whorled leaves—narrow and lance-shaped—arranged in circles around the stem. In spring, it produces small, star-shaped white flowers. When dried, the leaves develop a characteristic sweet, hay-like scent due to the compound coumarin, which intensifies upon wilting or drying.

USABLE PARTS: Leaf

MEDICINAL PROPERTIES:
Traditionally used for its mild diuretic, anti-inflammatory, and sedative effects. Employed in herbal medicine for kidney support, insomnia, nervous tension, and minor inflammation.

UNDESIRED EFFECTS:
Contains coumarin, which can be toxic in large doses. Avoid high intake and long-term use. Not recommended during pregnancy or in those on blood-thinning medications.

COMBINING WITH OTHER MEDICINES:
Often combined with lemon balm or chamomile for calming herbal teas or with lavender in aromatic sachets.


PREPARATION:
Leaves are dried and used in herbal teas, potpourri, infused vinegars, or as a flavoring in beverages (e.g., traditional German Maibowle).

HARVEST TIME:
Late spring to early summer, just before or during early flowering when the scent is strongest.

HARVEST METHOD:
Cut stems gently in the morning after dew dries. Use scissors to avoid uprooting the shallow-rooted plant. Dry immediately to preserve aroma.

CONSERVATION (STORAGE):
Hang dry in bunches away from light and moisture. Store dried leaves in sealed containers in a dark, cool location. Best used within 6–12 months.
