The product contains four components: young cedar cones, sugar, water, and concentrated lemon juice. No additional preservatives, colors, artificial flavors, or thickeners are listed. The cones are the defining ingredient — they're harvested young, while still soft and resinous, which allows them to infuse the syrup during cooking.
For dietary considerations: it is vegetarian. Whether it's vegan depends on the sugar refining method; some white sugar is processed with bone char, so strict vegans may want to contact the manufacturer for clarification. It is not sugar-free or low-sugar — this is a sweet preserve where sugar is a primary ingredient by weight, so it's not suitable for diabetic or low-carb diets without careful portion control.
Allergen-wise: the lemon juice means it contains citrus. The cedar cones are from a conifer (Siberian cedar / Pinus sibirica), so anyone with known sensitivity to pine, cedar, or other conifer resins or pollen should avoid it. Cross-contamination with nuts, gluten, or dairy isn't mentioned in the source, but if you have severe allergies, check the label for a "may contain" statement or contact the producer.
As with any sweet preserve, moderation is sensible. The "Good to know" note advises avoiding it if you're sensitive to any ingredient and stopping use if an allergic reaction appears.
