Herbal syrups combine a concentrated herbal preparation (a decoction or infusion) with a sweetener (sugar, honey, or glycerine) to produce a stable, pleasant-tasting medicine that is one of the most practically useful preparations in the home apothecary. They are easy to take (children usually accept them willingly), shelf-stable for months, appropriate for all ages with appropriate adjustments, and represent a tradition that goes back through every period of herbal practice.
The Basic Method: Simple Syrup Base
Make a strong herbal preparation: for a decoction (appropriate for roots, bark, and berries), combine herb and cold water in a saucepan, bring to a boil, reduce heat and simmer uncovered until the liquid has reduced by half. For an infusion (appropriate for flowers, leaves, and delicate herbs), pour just-off-the-boil water over the herb, cover, and steep for 20 to 30 minutes. Strain and measure the resulting liquid.
For a sugar-based syrup: combine equal volumes of herb liquid and sugar in a clean saucepan. Heat gently, stirring, until the sugar dissolves completely. Do not boil. Add a tablespoon of apple cider vinegar per 500ml of syrup as a natural preservative. Bottle in sterilized dark glass and refrigerate. Keeps for three to six months.
For a honey-based syrup: prepare the herb decoction or infusion, allow to cool to below 40 degrees, then combine with an equal volume of raw honey, stirring until fully dissolved. Never heat honey. Bottle and refrigerate. Keeps for two to three months.
The Best Syrups to Make
Elderberry syrup is the classic winter immune syrup. Thyme and honey syrup is the traditional European cough remedy. Elderflower and honey syrup for upper respiratory infections and sinus congestion. Chamomile and lemon balm syrup for children’s anxiety and sleep. Licorice root and marshmallow root syrup for a deeply soothing respiratory preparation for dry, irritated coughs.
Storing and Dosing
Adult dose for most therapeutic syrups: one to two tablespoons, three times daily during acute illness; one tablespoon daily for tonic use. Children’s doses are adjusted by weight. The Herbalist Codex app has preparation guidance for each of these syrups alongside the individual herb profiles, with specific dosing notes and any important safety considerations.
